Introduction

Avian medicine is a rapidly growing field, with an increasing number of exotic bird species being kept as pets. However, the unique anatomy, physiology, and behaviour of these birds present several challenges as well as new opportunities for veterinarians and researchers.Now a day’s birds are gaining popularity over dogs and cats because of various reasons listed below:

a. They are more suited in present life style as can be suited well in small spaces.

b. They require low maintenance with relative low cost of maintenance and live longer life.

c. They form very strong bonds with their owners.

Birds can be classified into different families, such as Psittaciformes, Passeriformes, Columbiformes, Piciformes, Anseriformes, Galliformes etc. containing numerous species (>10,000). The first documentation of parrot as a pet was found in Rig Veda, written more than 3000 years ago. Evidence of bird keeping is observed in ancient civilizations of Greece, Rome, China and Egypt. In Greek mythology, Raven (a crow) was mentioned as a symbol of good luck and was associated with God Apollo (God of prophecy). Crows are also considered as ancestors in Hindu mythology and food (pinda) is offered to crows during ritual of paying homage to dead persons. In most of the countries psittacine and passerine birds are preferred as pet birds.

Introduction

Canine epilepsy, a prevalent neurological disorder, significantly impacts the quality of life for both dogs and their owners. Traditional anticonvulsant therapies often yield inconsistent outcomes, necessitating the exploration of alternative treatments such as homeopathy [1][2]. Homeopathy’s individualized approach aligns with the principles of unicism, focusing on holistic care tailored to each patient’s unique symptom profile [3]. However, the subjective nature of remedy selection and response assessment poses challenges for practitioners.

The integration of Artificial Intelligence (AI) and Machine Learning (ML) offers a promising avenue to address these challenges [4]. Predictive models can analyze complex datasets to uncover patterns that guide remedy selection and treatment strategies. This study evaluates the comparative performance of Logistic Regression, Random Forest, and XGBoost in predicting treatment outcomes for canine epilepsy managed with homeopathic remedies.

Introduction

Wound is a disruption to the epithelial integrity of the skin, extended in-depth to subcutaneous tissue and other body parts such as ligaments, muscles, blood vessels, nerves, and bone (Robson et al. 2001). An appropriate wound healing is essential for the restoration of disrupted anatomical continuity (Begum, 2000). We have observed increasing interest in research based on traditional medicines of the world in the recent era (Medina-Franco et al. 2013). Traditional and complementary medicine regains popularity not only in developing countries but also in developed countries. Common and known practices across the globe of traditional medicines include Herbal, Ayurveda, Siddha, Unani, Iranian, Islamic, Vietnamese, Chinese, Acupuncture, African and other pseudo-medical knowledge (Dorai 2012). According to World Health Organization (WHO), traditional medicine ‘the health practices, approaches, knowledge and beliefs incorporating plant, animal and mineral-based medicines, spiritual therapies, manual techniques and exercises, applied singularly or in combination to treat, diagnose and prevent illnesses or maintain well-being’. Saxena et al. (2013) reported that phytochemicals present in plants are liable for preventing disease and promoting health. Antibiotics used in the treatment of wound infections are now proved to have adverse effects in the human body and in pathogens where resistance is emerging. Attention has, therefore, turned towards extracting biologically active compounds from plant species having wound healing property (Pattanayak and Sunita, 2008).

Introduction

As India is the leading global economy with livestock contributing 4.66% in total GVA to Indian Economy (PIB, 2024) and ranks 1st in Milk Production, 2nd in Egg production, 5th in meat production (BAHS, 2024). Being the largest exporter of milk and meat in the world , this has led to the intensification of animal production due to the increasing demand of major livestock products (MLPs), which has led to an increasing overall use of antimicrobials. Antimicrobials are invariably used to preserve animal and public health, but also as growth promoters at a sub-therapeutic level. The overuse and misuse of antibiotics can contribute to antimicrobial resistance. The growing resistance to antimicrobial drugs could reverse the therapeutic benefits; animals’ resistance to antimicrobial drugs, reduces productivity and leads to economic losses. Unwanted antimicrobials residues may be present in products of animal origins, in animal waste contaminating soil and water and the environment. Seventy-five to ninety percent of antimicrobials used in livestock are excreted, mostly unmetabolized. AMR poses a serious threat to the safety and quality of animal origin food, food security and livelihoods. Unhealthy and unproductive animals are no longer able to generate food products of acceptable safety and quality for human consumption and can no longer contribute to income generation. Insufficient standards for residues in animal food products, reduces the livestock sectors potential of access to trade and increases public health risks (https://www.fao.org/antimicrobial-resistance/key-sectors/animal-production/ en/).

By 2050, the global population is projected to reach approximately 9.8 billion, requiring a 70% increase in food production to meet the growing dietary demands. The livestock sector will play a crucial role in addressing this rising need through sustainable animal production, contributing to food security, poverty alleviation, public health, and food safety. To tackle the challenges posed by population growth and to achieve the United Nations Sustainable Development Goals (SDGs), technological advancements and innovations will be essential in transforming the food and agriculture sectors.

In light of these challenges, Veterinary Services are more critical than ever. They are essential for enhancing livestock health and productivity, ensuring high-quality food that meets safety standards, and mitigating risks associated with animal diseases and public health. Additionally, Veterinary Services must contribute to global efforts in addressing issues such as food security, antimicrobial resistance, climate change, and the depletion of natural resources.

Fruits are an important supplement to the human diet, as they provide minerals, vitamins and fiber required for maintaining good health. Fruits are also rich in phytochemicals (7, xanthophylls, polyphenols, flavonoids, phenolic acids, organic acids etc.) which possess good antioxidant properties. India’s diverse climatic conditions ensure availability of almost all the varieties of fresh fruits and vegetables. According to FAO (2021), the country ranks first in the production of bananas (26.45%), mangoes (including mangosteens and guavas) (43.80%) and papayas (39.30%). The scenario of horticulture crops in India has become very encouraging. The percentage share of horticulture output in agriculture has become 33 per cent (Anonymous 2021). India has witnessed increase in horticulture production over the last few years. Significant progress has been made in area expansion resulting in higher production. Over the last decade, the area under horticulture grew by 2.1 per cent per annum and annual production increased by 3.9 per cent. During 2020-21, the production of horticulture crops was 334.60 million tonnes from an area of 27.74 million hectares. The production of fruits has increased from 76.42 million tonnes in 2011-12 to 108.34 million tonnes in 2022-23 (Agricultural Statistics at a Glance 2022). The area under cultivation of fruits stood at 7.05 million hectares. The total production of fruits in the year 2020-21 was highest in case of Andhra Pradesh (17.70 million tonnes) followed by Maharashtra (11.73 million tonnes) and Uttar Pradesh (11.23 million tonnes) (Anonymous 2021). India now is the second largest producer of vegetables and fruits in the world. The country ranks at first position in the production of banana, mango, lime and lemon, papaya and okra. The area and production of fruits in India is presented in Table 1. The fruits namely banana, mango, citrus, papaya, guava, grapes, apple, pineapple and sapota account for more than 85 per cent of the total production of fruits. The other fruits which are produced in India are almond, walnut, jackfruit, bael, ber, custard apple, kiwi, passion fruit, peach, pear, plum, strawberry etc.

Horticulture crops contribute significantly for the total agricultural production and productivity. World production of fruits accounted for the total volume of 933 million tonnes (FAO, 2023). India being second largest producer for majority of fruit commodities had a production total reaching 108.34 million tonnes in 2022-2023 from an area of 7.15 million hectares. It accounts for 33 per cent to the agriculture GVA (Gross Value Added) and plays an important role in the Indian economy. India is second largest producer of majority of fruits and vegetables. Diverse agro-climatic zones in the country make it possible to grow almost all varieties of fruits in India. Produced fruits are used for domestic consumption, processing and export purposes. During 2022 23, fresh fruits exports was valued at 6219.46 crores (APEDA, 2023). The fruits grown in India includes domestic fruits and nuts along with the exotic fruits contributing for the food and nutritional security. The growth of these economically important fruits provides scope for maintaining rich germplasm, enhance bio-diversity and maintain ecological balance.

Fruits represent a vital component of global agriculture, serving as not only a significant source of essential nutrients but also a lucrative sector of the economy. However, from the moment of their inception on the tree to their arrival on consumers’ tables, fruits undergo a complex journey influenced by a myriad of factors. Among these, pre-harvest practices wield a profound impact on fruit quality, enzymatic activities, texture, ripening, and ultimately, post-harvest transportation losses. Each pre-harvest practice, from mineral nutrition to harvesting methods, plays a distinct role in shaping the biochemical composition and physical attributes of fruits, ultimately affecting their marketability and shelf life. Mineral nutrition stands as one of the foundational pillars of fruit production, with essential minerals serving as building blocks for various biochemical processes. Irrigation practices represent another critical aspect of pre-harvest management, as water availability profoundly impacts fruit development and composition. Different irrigation regimes can influence enzymatic activities, fruit texture, and the timing of ripening, necessitating strategic water management to achieve desired fruit quality while minimizing post-harvest losses. Canopy regulation, achieved through training and pruning techniques, offers growers a means to manipulate light penetration and airflow within the orchard. Moreover, the application of plant growth regulators (PGRs) emerges as a tool for fine-tuning fruit development and ripening processes. By modulating hormonal signals, PGRs can alter enzymatic activities, influence fruit texture, and mitigate transportation losses. However, judicious application is paramount to avoid adverse effects on fruit quality and safety. Harvesting decisions, including the determination of optimal maturity and the timing and method of harvest, profoundly impact fruit quality and post-harvest losses.

Horticulture sector, comprising fruits, vegetables, floriculture, medicinal and aromatic crops, mushroom, spices and plantation crops, had witnessed phenomenal growth in production and productivity during the last two decades. Resultantly, horticulture in India is recognised as one of the fastest growing sectors in the world. The production has reached to 351.92 million tonnes in 2022-23 as compared to 231 million tonnnes in 2010. Progressive urbanization, increased spendable income and awareness for balanced and nutritious food have contributed towards increasing demand of horticulture produce. The increasing demand coupled with higher income returns per unit area has triggered this growth pattern, which has been largely possible due to policy environment to support horticulture both for research and development.

Introduction

Fresh fruit journey from the farm to the consumer’s table is an intricate process which needs a lot of attention. The way that the produce is harvested and handled is of supreme importance in relation to its quality shelf life and general market attractiveness. Improper handling practices during these critical stages can bring both quantitative and qualitative loses hence the perishable produce will lose its commercial value and appeal to the consumers (Kader, 2005). No doubt the significance of successful harvesting and post-harvest handling practices is crucial and has an impact on quality features and safety in case of fresh fruits. Poor management can cause physical assault ripening speed and more susceptibility to the growth of micro-organisms which makes the produce unsuitable for consumption or processing.

The production of fruit crops is largely dependent on the environmental conditions and nutritional status of the plants. Any alteration in the environmental conditions and nutritional status may results in different physiological disorders which affect the growth of the plants and also the quantity as well as quality of the fruits. The precise and early recognition of physiological disorders is important for the timely adaptation of remedial strategies to reduce the crop loss. Physiological disorders in fruits crops may be due to single factors or multiple factors may be involved in the appearance of physiological disorders. A sound knowledge about the cause of physiological disorder is useful to adopt suitable remedy for the disorder.

Introduction

The abnormal growth behavior or unusual external and/or internal conditions of fruits which results due to adverse environmental conditions and nutritional imbalances are considered as physiological disorders. Physiological disorder is best defined as external or internal malfunctioning resulting from improper environmental or cultural conditions before and/or after harvest. Variation from normal temperature, light, moisture, nutrient, harmful gases, insufficient supply of growth regulators, deficiencies or excesses of nutrient etc. are some of the important environmental and cultural factors of physiological disorders (Fig. 1). Physiological disorders affect the quality as well as quantity of the fruit crops. Detection of precise physiological disorders is not easy and requires a strong knowledge regarding them.

India is the second largest producer of fruits However, the export potential of fruits and vegetables is very negligible. This is because of improper knowledge to the farmer about proper post-harvest infrastructure facilities. Fruits have a high-water content ranging from 70-95 per cent. They dry quickly under any normal atmospheric condition. These causes loss of rigidity and shrinkage of the cells cause wilting and shrivelling. Appropriate packaging ensures prolonged the shelf life of fruits and vegetables by preventing moisture loss and thereby wilting. Transportation is a critical phase in the fruit supply chain that can significantly affect the quality of fruits. Several factors during transportation can lead to quality degradation such as temperature/humidity fluctuations, mechanical damage, transit time etc. To mitigate the adverse effects of transportation on fruit quality, best practices ie, real-time monitoring, temperature and humidity control, loading/unloading techniques can be employed. Quality evaluation is a critical component in the fruit industry, encompassing a range of assessments to ensure fruits meet the desired standards for consumer satisfaction, shelf life, regulatory compliance, and market competitiveness. It involves a comprehensive approach that includes physical, chemical, and sensory assessments, supported by advanced technological tools, to maintain and enhance the quality of fruits throughout the supply chain. This book chapter deals with the effective packaging, transportation, and quality evaluation of fruits, ensuring that consumers receive fresh, high-quality produce.

Introduction

India is bestowed with huge production of fruits, vegetables, cereals, millets, sugarcane along with meat production, milk production, fish production and poultry. Despite such a huge production in India, owing to perishable nature of these produce around 25-30 per cent of the produce is being lost as post harvest loss. The one important reason for this may be the production of the crops are season specific and during the peak season the production is more while demand for consumption is less. It may be possible to cut down losses to great extent, if these produces may be transported from the produce states to those who are not producing due to agro-climatic reasons. So for making transportation of the perishable a successful venture in decreasing post harvest loss, there must be proper storage facilities both at producing site as well as marketing place. The aim of the storages must be to keep the produce in saleable condition during entire storage periods. Some products are stored for short period whereas fresh fruits, vegetables require cold storage. Foods before keeping into the storage room need some pre-storage treatments for better results.

Introduction

Agricultural production is necessary to fulfil nutritional requirements for human populations and global food security. The agricultural sector also forms the economic backbone of many low-income countries in which millions of farmers are employed (Anushka et al, 2022). However, managing agricultural production to achieve multiple objectives of providing food, supporting livelihoods and protecting biodiversity and forests is a challenge especially in tropical, low-income countries (Anushka et al, 2022). Usually, the growth in global agricultural production is largely driven by commercial and export oriented commodities. One such agricultural commodity that has high global demand is cashew (Anacardium occidentale L.). Cashew is presently cultivated in 33 countries including India in the world. Global land area for cashew cultivation between 1980 and 2018 has seen an eleven-fold increase from 526,250 ha to 5,972,724 ha (Anushka et al, 2022).

Coconut, arecanut and palmyrah, which hold significant cultural and historical importance in India, have been the primary focus of cultivation efforts. Cocoa, a relatively recent addition to India, serves as a companion crop to coconut and arecanut, contributing to the economic well-being of farmers nationwide. However, the current situation emphasizes the crucial role of value addition and product diversification in stabilizing prices. Despite the initial stages of value addition in India’s palm crops, recent innovations and established value chains have the potential to empower farmers as entrepreneurs, thereby augmenting their income. Moreover, the value-added products from these palms have enormous export potential. This chapter explores the advancements in value-added products and the diversification of coconut, arecanut, palmyrah, and cocoa, providing insights into opportunities for cottage or small-scale industries.

Oil palm is a major source of edible oil globally and plays a crucial role in meeting the dietary needs of millions of people. India has been focusing on expanding oil palm cultivation to reduce its dependence on imported edible oils. Oil palm can yield high oil compared to other vegetable oils. Palm oil production rate depends on post-harvest handling, and milling and extraction processes. After harvesting, some quality changes occur in oil palm fresh fruit bunches which leads to reduce the oil quantity and quality. With proper handling of post-harvest bunches and adapting best extraction methods can increase the oil yield and quality. Palm oil alone has the potential to make India sustainable in edible oil production.

Introduction

Oil palm (Elaesis guineensis Jacq.) originated in the tropical rain forest of western Africa and is now being cultivated in more than 45 countries around the world especially tropical regions i.e., Malaysia, Indonesia, Thailand, Nigeria, Columbia, and Ghana. This crop was introduced in India during the early 1990s, to meet the demand and to attain sustainable edible oil production in India due to its high oil-yielding capacity compared to other vegetable oil crops. It produces two distinct oils, i.e., palm oil and palm kernel oil. Palm oil is derived from fleshy mesocarp of the fruit and palm kernel oil obtained from the kernel of stony seed.

Foot and Mouth disease

Foot and mouth disease is a contagious viral disease of cloven footed animals caused by a picorna virus and characterized by presence of vesicles in oral mucosa and foot (Fig.1.1).

Etiology

• RNA virus of picornaviridae family

• Picorna virus

• Serotypes A,O,C, SAT-1, SAT-2, SAT-3, Asia-1, serotype ‘O’ is most common in India.

Pathogenesis

Inhalation is the main route of infection in ruminants; however, ingestion of contaminated feed and water, inoculation of contaminated vaccines, insemination with contaminated semen and contact with fomites such as clothing, instruments etc. may also transmit the infection. When animal gets infected through respiratory tract, viral replication starts in pharynx followed by viraemic spread to other tissues and organs like epithelium of mouth. Viral excretion commences about 24 hours prior to the onset of clinical form of disease and continues for several days. The aerosols of infected animals contain large amount of virus particularly of swine. Large amount of virus is excreted in milk. In cattle and sheep, virus may be detectable up to 2 years and 6 months of exposure, respectively.

Tuberculosis

Tuberculosis is a chronic bacterial disease of cattle, buffaloes, sheep, goat and pigs caused by Mycobacterium sp. and characterized by presence of tubercle nodules in lungs, spleen and lymph nodes (Fig.2.1).

Etiology

• Mycobacterium tuberculosis

• M. bovis

Pathogenesis

Disease spreads through contact with infected animals or their discharges or morbid tissues. The infected animals release the organisms through sputum at coughing and contact animals get infection through droplet inhalation.Besides sputum, faeces, urine, vaginal discharges, semen, milk, lymph and wound discharges may act source of infection. It is also transmitted through contaminated instruments, utensils and beddings. After entry through inhalation or ingestion, bacilli localizes at the point of entry and produce typical tubercle in associated lymph nodes. Mostly pharyngeal and mesenteric lymph nodes are affected. From lymph nodes, infection may extend across body cavities, blood vessels and lymph vessels. The inhaled organism enter in the bronchial tree after lodging in bronchi a tissue reaction takes place. Neutrophilic infiltration is there and when neutrophils are necrosed, macrophages come to destroy the organism but they fail then many macrophages becomes elongated to form epithelioid cells, the hall mark of granulomatous inflammation. Some macrophages are joint together to form giant cells to destroy the acid fast bacilli. As a consequence of this some bacilli are phagocytosed and are destroyed. A zone of lymphocytes, macrophages, epithelioid cells, giant cells and fibrous connective tissues are formed around the central necrosed area.

Chlamydiosis

Chlamydiosis is an infectious disease of animals caused by Chlamydia sp. and characterized by encephalitis, polyarthritis and pneumonia in calves and abortions in cows and sheep.

Etiology

• Chlamydia psittacii

Pathogenesis

Chlamydial infection spreads through inhalation of contaminated dust from infected birds. Organism multiplies in lungs and through blood it spreads to liver, spleen, kidneys, brain, joints and placenta to cause pathology.

Characteristic symptoms

Calves

• Fever, dyspnoea

• Nasal discharge, hypersalivation

• Swelling of joints

Anaplasmosis

Anaplasmosis is an infectious disease of animals caused by a rickettsia and characterized by icterus, enlargement of spleen, pale tissues, thin watery blood and petechiae over serous membranes (Fig.4.1).

Etiology

• Anaplasma centrate

• A. marginale

• A. ovis

Pathogenesis

The disease is transmitted through bite of tick (Boophilus), biting flies (Tabanus) and also in some cases due to mosquitoes. It is intra cellular organism and multiplies inside the erythrocytes by binary fission. The infected erythrocytes are engulfed by the cells of reticuloendothelial system (spleen, bone marrow). The process of erythrophagocytosis cause extra vascular haemolysis leading to anemia. It also causes autoimmune reaction leading to lysis of erythrocytes.

Contagious

Bovine Pleuropneumonia (CBPP) Contagious bovine pleuropneumonia (CBPP) is an infectious disease of cattle caused by Mycoplasma sp. and characterized by cuprous pneumonia, pleurisy and dilation of lymph vessels (Fig.5.1).

Etiology

• Mycoplasma mycoides

Pathogenesis

The infection spreads through inhalation of droplets from infected animals. The recovered animals act as source of infection at least for a period of 3 years. After entering through respiratory tract the organism reaches to bronchioles. It may remain in retropharyngeal gland from where it may spread in whole body. The organism from bronchioles enter into interlobular septa and causes inflammation followed by edema which causes dilation and subsequent thrombosis of lymph and blood vessels prior to development of pneumonic lesions. Death occurs due to anoxia and toxaemia.

Leptospirosis

Leptospirosis is an infectious disease of animals caused by spirocheate Leptospria sp. and characterized by widespread haemorrhage in visceral organs, nephritis, icterus, hepatitis and anemia (Fig.6.1).

Etiology

• Leptospira ictehaemorrhagae

• L. pomona

Pathogenesis

The organism is transmitted through direct contact with urine of infected animals or ingestion of urine contaminated feed or water. It can also be transmitted through aborted fetuses and infected uterine discharges. The organism enters through abraded skin and mucous membrane and reaches in blood and multiplies rapidly in blood producing septicemia and high rise in body temperature. Thereafter the organism localizes in the kidneys leading to acute or chronic nephritis. In kidneys, it multiplies in proximal convoluted tubules (PCT) and is excreted in urine which acts as source of infection.

Spongiform encephalopathy

Spongiform encephalopathy is an infectious disease of animals caused by prion proteins and characterized by presence of vacuoles in brain.

Etiology

• Prion proteins

• Sheep – Scrapie or Ovine spongiform encephalopathy

• Cattle - Bovine spongiform encephalopathy (Mad cow disease)

• Feline encephalopathy

Pathogenesis

Scrapie is also known as ovine spongiform encephalopathy. The principle means of transmission of disease is from infected mother to their lambs early in life; placental transmission has also been reported. The incubation period of disease is very long (2-5 year). The clinical form is restricted in adults. The prion proteins (PrP) occur normally in the central nervous system of all domestic animals and man bounded with neuronal surface. Animal susceptible to prion disease have a gene (PrP gene) which encodes for normal “Prion protein (PrP)” or “cellular prion protein (PrPc). In scrapie prion protein (PrPsc)/ scrapie associated fibril protein (SAI) is generated which are resistant for protease digestion. Accumulation of PrPsc in neural tissues appears to be the cause of the pathology in prion disease. When prion protein contaminated meat and bone meal are fed to the cattle as part of their concentration, the agent (prion) got introduced into cattle. Prion protein (PrP) on reaching brain slowly and progressively converted into and abnormal form (PrP sc) and this abnormal protein causes development of lesions including vacuolation in nerve cells.

Ringworm

Ringworm is a fungal disease of skin affecting animals characterized by popular skin lesions in circular form discharging serus exudate.

Etiology

• Microsporum canis- dogs

• M. gypseum- dogs, horse, pig

• Trichophyton verrucosum- bovines

• T. equinum- horses

Pathogenesis

The fungi enter in skin through abrasion and the hyphae appear in stratum corneum after germination and invade the hair follicles. The hyphae growth and spore formation in stratum corneum leads to hyperkeratosis and the fungus spreads centrifugally from the point of primary invasion leading to ring shaped lesion (Fig.8.1).

Trypanosomosis

Trypanosomosis is an infectious disease of animals caused by protozoan parasite and characterized by emaciation, enlargement of spleen and lymph nodes, petechiae on serous membranes, ulceration on tongue and gastric mucosa and gelatinous exudate in subcutaneous region.

Etiology

• Trypanosoma evansi

Pathogenesis

The disease is mainly transmitted through bite of flies like Tabanus, Stomoxys, Haematopota etc. The carrier animals remain as potential source of infection. The pathogenesis of disease is not completely known. After entering in mammalian host, trypanosomes multiply in blood stream by binary fission leading to parasitaenia. The parasites has variable surface glycoproteins which cause continuous exposure of immune system leading to hyperplasia of spleen and lymph nodes. In chronic cases, due to formation of antigen- antibody complexes glomerulonephritis and vasculitis is seen.

Equine Rhabdomyolysis

It is also known as Azoturia or Monday Morning Disease. The disease occurs in well fed horse after a spell of inactivity. Suddenly after walking a few steps, the horse is unable to move further and feels pain with intense sweating and hardening of muscles.

Etiology

• Accumulation of lactic acid in muscles.

• High glycogen storage.

• Lack of oxygen supply.

Cyanide poisoning

Cyanide poisoning occurs in animals due to sorghum and/or other chemicals and characterized by ataxia, incoordination, cystitis, paralysis, and death.

Etiology • Sorghum – drought resistant varieties.

• Fumigants, fertilizers,

• Pesticides.

• Industrial leakage/waste, electroplating.

• Photographic processes.

Tyzzer’s disease

Tyzzer’s disease is an acute infectious disease of laboratory animals including rats caused by Clostridium spp and Characterized by watery diarrhoea, necrotic hepatitis and death

Etiology

• Clostridium piliforme

• Gram positive, Spore forming, Anaerobe

• Bacteria in gut causing enteritis

Feline Leukemia

Feline leukemia is an infectious viral disease of cats, lion, tiger etc. caused by oncorna virus and characterized by malignant lymphoma, lymphocytosis and immunosuppression. It is also known as feline lymphoma or feline lymphosarcoma.

Etiology

• Oncorna virus of retroviridae family

• Type C oncorna virus, RNA virus has reverse transcriptase

Pathogenesis

The virus is transmitted horizontally through salivary and nasal secretions of sick cats. It affects lymphocytes causing their proliferation leading to production of neoplastic growth.

Characteristic symptoms

• Enlargement of superficial lymph nodes

• Lymphocytosis

• Chronic diarrhoea

• Abortion

1. Introduction

The agricultural sector plays a pivotal role in driving economic development in India, a nation with a population of 1.39 billion, making it the world’s second most populous country according to the United Nations’ World Population Prospects 2019. With 54.6 percent of the workforce engaged in agriculture as per the 2011 Census, and contributing 18.6 percent to the Gross Value Added (GVA) in 2021-22, its significance cannot be overstated. Notably, women play a substantial role in this sector, with rural females exhibiting a higher workforce participation rate of 41.8 percent compared to 35.31 percent for urban women (MoSPI, 2017). In rural communities, agriculture and allied sector is the primary source of livelihood that includes 80 percent of all economically active women, out of which 33 percent constitute agricultural labour force and 48 percent are self-employed farmers. Rural women are engaged at all levels of the agricultural value chain; i.e., production- pre-harvest, post-harvest, processing, packaging, marketing to increase productivity in agriculture (Nilam Patel etal, 2022). As per Pingali et al. (2019), the ratio of women to men working in the agricultural sector has increased over the time and made a greater amount of contribution to GDP per capita. They are the momentous demographic group for a sustainable food system (FAO, 2011). Empowering women in agriculture through reforms aimed at ensuring equal access to resources, skill development, and opportunities is projected to increase agricultural output in developing countries by 2.5 to 4 percent (FAO, 2011).

1. Introduction

Fish forms an integral component of the Indian food basket and it is more so for the population living in the eastern and north eastern States of India. The eastern states of India include States such as West Bengal, Bihar, Jharkhand and Odisha. As per a current estimate of 2023 (https://www.indiacensus.net), approximately a population of 31.66 crore, i.e. 22.15% of the country’s total, live in these four States. Due to the suitable geographical terrain, these states have been bestowed upon a large number of riverine stretches, a large number of natural reservoirs of varied sizes, beels and floodplain wetlands, and a huge plain terrain supporting ponds and tank resources. Due to the very nature of the land and the popularity of fish among the populace, these eastern Indian states have also served as the main stage for the development of fisheries and aquaculture during the last centuries in the country. Further, many of the epoch making technologies for the development of fisheries in the inland waters as well as aquaculture in the ponds have originated from this region.

1. Introduction

India has 536.76 million livestock as per 20th Livestock Census 2019. Livestock plays a vital role in improving the socio-economic conditions of rural masses especially for landless and marginal farmers; as well as an important role in the national economy. Livestock production and agriculture are closely related and vital for the overall food security. Agriculture diversification through animal husbandry is one of the primary factors of growth in rural incomes. A higher public investment in livestock sector is the need of the hour for doubling farmers’ income. Future economic growth would have to come from improvements in animal productivity. India is bestowed with a great degree of livestock biodiversity which can be elucidated in hosting more than 200 breeds across all the species. Along with producing A2 milk, desi cattle are renowned for withstanding heat, illness resistance, immunity to ticks and parasites and low maintenance requirements. The various indigenous breeds of agricultural animals are mostly the consequence of evolutionary processes. They were improved through field progeny testing & selection. Conservation and propagation of most precious high producing elite buffalo germplasm though the cloning technique is the contribution of the scientists to the buffalo rearing farmers of the country. The Indian Jamunapari goat is one of the ancestors of the American Nubian. Goat milk is an excellent source of vitamin A, is high in digestible protein, contains significantly lower levels of alpha-S1-casein, contains slightly less lactose, and has more non-digestible carbohydrates than cows’ milk.

1. Introduction

Cattle are one of the important livestock species of the country which forms an integral part of Indian agriculture since ages. Human progress depends on the utilisation of animals and natural resources in a balanced way. Cow, in particular, is considered as a part of the family in India. Cattle have been of the utmost importance for the sustenance of agriculture, nutrition supply and religious practices in India. Frequent references on cattle farming are found in Indian mythological books and historical writings regarding their utilization in agriculture as draught power, milk production and source of manure. Approximately 200 million Indians are involved in livestock farming, including around 100 million dairy farmers. Roughly 80% of bovines in the country are low on productivity and are reared by small and marginal farmers. Most of the local cows are managed on a low input and low output system for production of milk for the household nutritional requirement and sale surplus milk to dairy co-operatives or local milk sellers. Poor genetic makeup of Indian livestock is the main reason for their lower productivity as compared to the recorded potential of animals in temperate climate. With the change in food consumption pattern due to urbanization, increase in health awareness, reduced requirement of draught animal power due to mechanisation, etc., the demand for milk and milk products have increased many folds.

1. Introduction

Poultry industry in India stands out as a major success story. It’s phenomenal that India’s poultry production whichstarted justas a backyard venture before 1960s, has shaped up into a proven agribusiness, where its annual turnover exceeds Rs 30,000 crores. Current global ranking of India is that of number three, in terms of egg production (behind China [1st] and USA [2nd]), and of18th position in Broiler production. Today, Poultry is one of the fastest growing industries of the agricultural sector in India at present. The annual growth of broilers and egg production is 8-10% compared to 1-2% for production of agricultural crops [3].

Poultry production forms an important Agrarian Avenue providing valuable animal proteins for the fast-growing human population of the developing India, with promises of additional income to small and marginal farmers.Rural and backyard poultry farming is very common among landless and marginal farmer families in India and is a rewarding source of additional income. It involves low investment with high returns which can be easily operated by women, children and elder members of the farm families. Poor households generate good income through backyard poultry farming which provides meat and egg rich in protein and energy. Agriculture including animal husbandry provides 30-40% employment in terms of man/woman days in a year. Scarcity of land holdings, land fragmentation and seasonal agriculture aresome of the reasons that crop production only is unable to provide cent percent employment to the rural youths (men and women).

Women Folk: A Precious Resource

India’s ancient history ascribes a divine status to women. Laxmi, Durga and Saraswati are the three great goddesses of Prosperity, Power and Wisdom respectively. The ancient scriptures declared that ‘God lives where women are worshipped’. However, a multitude of derogatory attributes have been ascribed to women in the post-vedic period. According to Manu, “a woman must never be independent. In childhood, she must be subject to her father, in youth to her husband, and when her lord is dead, to her sons”. The passive role of women, unfortunately thus visualized, later guided the future course of action leading to their present status of backwardness in general and neglect in the streams of development and scientific arena in particular.

The term ‘gender’ was first used by Ann Oakley and others in 1970s to describe the characteristics of men and women which are socially determined in contrast to biological differences. The term ‘gender’ further explains, a neutral term meaning either men or women or both in a particular context. The goal is to improve the status of disadvantaged class and get rid of socially created and approved discriminations. The green revolution in India changed the face of agriculture but apparently it contributed to two general trends (FAO, 1996) where wealthy have benefited more from technological change in agriculture than the less well off andsecondly men have benefited more than women.

Introduction

Challenges in agriculture and natural resource management in the past have prompted changes in agricultural education, research, and extension globally. The sustainable development of agriculture in a country largely depends on the effectiveness of its agricultural extension strategies, encompassing approaches, service delivery, methodology, and processes. The desired outcome of agricultural development is farmers’ outcomes, achievable through engagement, learning, and participation in research and extension processes. Agricultural extension played a significant role in the green revolution by providing farming communities with appropriate technologies and optimal cropping practices. This helped countries transition from being food deficit to food exporting (Ratnakar, 2016). Additionally, extension services play a crucial role in expanding knowledge, skills, and attitudes about the management of socio-economic-agricultural practices by understanding the existing techno political ecosystem and exploring a basket of technology alternatives for making informed decisions.

India is a land of great diversities in terms of people, culture, languages and the style of living, among many other varied characteristics in the country. Based on the climatic, geographical, and cultural features, the country is broadly divided into six zones - the Northern, Southern, Eastern, Western zone, Central and the North-Eastern zone. Eastern zone comprises Bihar, Jharkhand, West Bengal, Odisha, Chhattisgarh, Assam and eastern UP (27districts of UP). This document exclusively focuses on the four states namely Bihar, Jharkhand, Odisha and West Bengal in the Eastern Zone with an attempt to look into the bottlenecks inhibiting the rural development of the zone.The f inancial institutions for agriculture in India was developed with the purpose of financing the needy farmers and providing them the facilities to increase the efficiency of agriculture. As a result, NABARD was formed in 1982. Thus, it was developed as an apex bank to help and support the agriculture section in India.This chapter seeks to evaluate the role of various financial institutions which play a major role in raising the standard of living of nearly one-fourth of India’s population in the eastern region of our vast country.

The National Agroforestry Policy of India is a comprehensive policy framework designed to improve agricultural livelihoods by maximizing agricultural productivity including animal productivity along with tree cover and mitigating climate change. The Government of India launched the policy in February 2014 during the World Congress on Agroforestry, held in Delhi. The focus of the policy is to address Agroforestry, which is an integrated system of practicing agriculture, livestock farming and forest activities on the same unit of land, storing high carbon, there by mitigating climate change. Agroforestry systems have the potential to be more beneficial than traditional agriculture and forest production practices. They may be able to give enhanced productivity, as well as social, economic, and environmental advantages, as well as a broader variety of ecological products and services. It’s important to remember that these advantages are contingent on appropriate farm management. In 2014 India became the first nation in the world to adopt an inter-sectoral policy on agroforestry, which seeks to identify the bottlenecks in expansion on agroforestry in the country and pathways to remove the constraints in a systematic manner.

India’s horticulture sector stands as a beacon of promise and potential within the agricultural landscape, showcasing a rich diversity of fruits, vegetables, tubers, spices, flowers, medicinal and ornamental plants as well as herbs. This sector provides livelihoods for millions of farmers and plays a crucial role in ensuring food security and nutritional well-being. Amidst the challenges posed by climate change and environmental degradation, the resilience of horticultural crops becomes increasingly significant. Diversifying towards resilient crops and sustainable practices not only mitigates risks but also enhances the sector’s adaptability to changing climatic conditions. Investment in research and development to breed climate-resilient varieties and promote agroecological approaches is imperative. Furthermore, promoting organic and niche horticulture products presents exciting opportunities for Indian farmers to capture premium markets both domestically and internationally. With growing consumer awareness and demand for healthy and nutritionally rich food, India’s horticulture sector is well-positioned to become a global leader in organic and exotic produce.The recent trend of exploring new crops within Indian horticulture promises to diversify farmers’ income sources and address emerging challenges such as climate change and shifting consumer preferences.

The land is one of the basic natural resources for agricultural growth and development of a country. Investment on agricultural land improvement by way of land leveling, contour bunding, sinking of well for irrigation and resorting to other measures like treating the soil to reduce acidity etc. have been continuous effort of agriculturists for increasing productivity.In addition, new variety of seeds which are high yielding and pest resistant are sought after by farmers for increasing production. Efficient land management encompassing soil and water conservation is the building block for sustainable agricultural development.

Land tenure rules define the ways in which property rights to land are allocated, transferred, used, or managed in a particular society. Ownership of land plays a significant role for improvement of land and its management. If the land is tenanted,the tiller of the land has less stake on long term measures on land.For centuries, the land tenure system in India was based on intermediaries known as Zamindary system.In Odisha, the tenurial system has based on the Bengal Rents Act, the Bengal Tenancy Act, the Bihar & Orissa Tenancy Act and finally, the Orissa Tenancy Act.In addition, theCentral Province Tenancy Act and the Central Province Land Revenue Act were in vogue in the Sambalpur district when the Orissa province was formed. Further, theGanjam district was under the Madras Estates Land Act(MELA). All these laws defined and classified the tenurial system.If one examines the OT Act one would find series of intermediaries between the proprietor and actual tiller of land.Tenure-holders had under-tenure holders. Raiyats had under-Raiyats. Tenants also inducted sub-tenants.

Introduction

Agriculture has been the cornerstone of human civilisation for millennia, providing sustenance and livelihoods to communities around the world. As the global population continues to grow, reaching an estimated 9.7 billion by 2050, the need to ensure food security becomes increasingly urgent. However, this burgeoning demand for food coincides with numerous challenges such as climate change, dwindling natural resources, and the pressures of sustainable farming practices. To address these complex issues and meet the world's food requirements sustainably, modern agriculture must embrace innovative technologies. One such game-changing technology that has emerged in recent years is Artificial Intelligence (AI), which is revolutionising various industries, including crop production. AI is the simulation of human intelligence processes by machines, particularly computer systems. It encompasses a range of capabilities, including learning, reasoning, problem-solving, perception, and language understanding. When applied to agriculture, AI holds immense promise to transform how we grow crops, optimise resource utilisation, and enhance overall productivity (Fan et al., 2012). By leveraging AI's power, farmers can make data-driven decisions, improve efficiency, and implement precision farming techniques tailored to specific field conditions. By employing AI technologies, it is possible to mitigate the impact on natural ecosystems and enhance worker safety. This, in turn, can contribute to keeping food prices down and ensuring that food production remains in step with the growing global population (Ranjan et al., 2023).

Introduction

Biofortification, also known as biological fortification, involves enhancing the nutritional content of food crops to improve bioavailability for the human population. This is achieved through the use of modern biotechnological techniques, conventional plant breeding, and agronomic practices. Unlike our current agricultural system, which primarily focuses on increasing grain yield and crop productivity, biofortification addresses the nutritional needs of the human population. The prevailing approach has led to a rapid increase in micronutrient deficiency in food grains, contributing to higher rates of micronutrient malnutrition among consumers. Biofortification presents a one-time investment that offers a cost-effective, long-term, and sustainable solution to combat hidden hunger (Sow and Ranjan, 2021a). Once biofortified crops are developed, there are no ongoing costs associated with purchasing fortificants and adding them to the food supply during processing. Agronomic biofortification methods involve the physical application of nutrients to temporarily enhance the nutritional and health status of crops. The consumption of such crops subsequently improves human nutritional status. Successful implementation of the biofortification initiative requires farmers to receive support for using micronutrient fertilisers on fortified cultivars and marketing assistance. Despite challenges, the biofortification of millets holds a promising future in addressing the issue of malnutrition.

Introduction

Crop modeling in agriculture involves utilising quantitative data on eco physiological processes to forecast plant growth and development, leveraging environmental conditions and management inputs. These models simulate how crops respond whether in terms of growth, yield, or other factors to a dynamic interplay of elements like management practices, water, weather, and soil parameters throughout a growing season. They serve as computational tools emulating the intricate growth patterns of crops by mathematically representing various facets within the cropping system (Nath et al., 2023). The roots of crop modeling trace back to the 1960s, when researchers began integrating physical and biological principles to model agricultural systems. These models heavily rely on measurable inputs, obtained via sensors, machinery, or manual measurements, to predict desired outputs such as plant growth, crop yield, soil nitrogen levels, or crop staging.

Crop Modeling

Crop modeling involves the creation of mathematical or computational models that represent the growth, development, and yield of crops. These models are based on scientific principles and empirical data, aiming to simulate and predict various aspects of crop behaviour under specific conditions. The primary purpose of crop modeling is to provide a theoretical framework for understanding and predicting crop responses to environmental factors, management practices, and genetic variations.

Introduction

Sustainable agriculture focuses on practices that ensure the long-term well being of the environment, society, and economy. In India, the government has instituted various policies and initiatives to encourage sustainable farming practices and enhance farmers' income. Embracing sustainability is crucial for making agriculture both profitable and environmentally friendly for future generations, and technology emerges as the key enabler for achieving this goal. Technological advancements empower farmers to make informed decisions regarding optimal planting and harvesting times, as well as the judicious use of water and fertilisers. This leads to reduced waste, increased crop yields, and ultimately higher profits for farmers. Additionally, technology plays a significant role in mechanisation, encompassing the use of modern agricultural implements that multitask while minimising soil impact (McFadden et al., 2023). Addressing major challenges such as crop residue management through environmentally friendly technological methods not only enhances efficiency and productivity but also reduces the physical labor required, transforming farming into a less strenuous occupation.

Introduction

The managemment of pests and diseases in agriculture is challenging for farmers. Antibiotics and chemical pesticides are commonly used in traditional methods, which can be harmful to human health, the environment, and the long-term sustainability of agricultural practices. This article explores innovative approaches to pest and disease management in agriculture that are changing the game (Lykogianni et al., 2021). Techniques for controlling diseases and pests in field crops are necessary to keep agricultural systems healthy and productive. Farmers and agricultural professionals can prevent, monitor, and control pests and diseases that can significantly affect crop yields in a variety of ways. These administrators are practicing strategies to find a balance between restricting the use of chemical inputs, promoting sustainable agriculture, and maintaining financial viability.

Principle of Integrated Pests and Disease Management (IPDM)

• Suppression and Prevention: The elimination and prevention of pests are the first tenets of IPM. IPM aims to prevent a single pest from dominating a cropping system or causing damage, not eliminate all pests (Barzman et al., 2015). Three distinct sub-principles are combined in this principle: crop rotation and management, ecology, and a multi-pest strategy in combination The papers in this Special Issue discuss each of these guiding principles. A genuine illustration of the mix of strategies and multi-pest approaches is crafted by Poggi et al. (2021), who discussed ways to control wireworms in field crops. A risk assessment based on the production context (such as crop, climate, soil characteristics, and landscape) and monitoring of adult and/or larval populations should be the first steps in any new agro-ecological strategy.

Introduction

The realm of agricultural policies and environmental policies stands as two critical pillars influencing the sustainability and equilibrium of our ecosystem. Agricultural policies primarily focus on regulations and measures instituted by governments or institutions to manage agricultural practices, production, distribution, and rural development. Conversely, environmental policies aim to safeguard and conserve natural resources, biodiversity, and ecosystems while mitigating the adverse impacts of human activities on the environment.

Overview of Agricultural and Environmental Policies

Agricultural policies often encompass subsidies, price controls, land use regulations, and trade agreements aimed at bolstering agricultural productivity, ensuring food security, and supporting rural economies (Fischer & Edmeades, 2010). Conversely, environmental policies encompass a broad spectrum of regulations, such as pollution control measures, wildlife protection, habitat conservation, and climate change mitigation strategies (Boyd & Banzhaf, 2007).

Importance of Understanding Their Interactions

Understanding the interactions between agricultural and environmental policies is crucial due to their interconnectedness and potential trade-offs. Agricultural activities significantly impact the environment through deforestation, water pollution from agricultural runoff, greenhouse gas emissions, and loss of biodiversity (Pretty et al., 2008). Conversely, environmental conditions greatly influence agricultural productivity and sustainability, including soil quality, water availability, and climate patterns. Recognition of these interdependencies is vital for devising coherent policies that foster sustainable agricultural practices without compromising environmental integrity (Tilman et al., 2011). The challenge lies in formulating policies that strike a balance between agricultural production goals and environmental conservation imperatives.

Introduction

Throughout their existence on this planet, human beings have adapted to the diverse environments they inhabit. Depending on the topography and prevailing natural conditions, individuals have successfully navigated the challenges posed by nature and their surroundings. As life has progressed, humans have gained insights into nature, its resources, and the prudent utilisation thereof. This understanding encompasses various natural phenomena, the associated challenges, and the methods to mitigate them. Over time, humans have evolved into repositories of such knowledge, collectively known as 'indigenous knowledge' or 'traditional wisdom,' passed down from one generation to the next. Each specific region possesses its unique set of indigenous knowledge reflecting the harmonious coexistence of humans with their environment.

Indigenous agricultural knowledge (IAK) stands as a crucial force in the realm of agricultural development. It represents a systematic and collective body of knowledge, practices, and beliefs that evolve through adaptation processes and are transmitted across generations through cultural channels, elucidating the intricate relationship between living beings and their environment. With this collective wisdom, farmers have adeptly cultivated food crops in diverse environmental conditions and seasonal variations, relying on indigenous techniques in the absence of external inputs, resources, and scientific knowledge. This includes refraining from the use of synthetic agrochemicals and instead embracing practices like crop rotations and soil fertility restoration through closed nutrient cycles (Melash et al., 2023).

Introduction

Embarking on the journey of legume cultivation in India reveals a nuanced landscape marked by both challenges and promising horizons. The agricultural scenario is akin to orchestrating a symphony, where legumes play a vital role, contributing melodies of resilience and significance. Unveiling this leguminous symphony in India is an exploration into the intricate interplay of obstacles and potential triumphs within the agricultural sector. As we delve into an overview of legumes, commonly known as pulse crops, their significance in Indian agriculture becomes apparent. Belonging to the Fabaceae family, these plants possess a distinctive feature - the ability to harness nitrogen from the atmosphere. This unique characteristic renders them pivotal components in sustainable agricultural systems, impacting not only food and nutritional security but also influencing the broader scope of soil fertility enhancement and economic prosperity. The journey through legume cultivation in India unfolds as a harmonious narrative, weaving together the challenges faced and the promising prospects that lie ahead in this agricultural symphony (Sow and Ranjan, 2021).

Introduction

Millet is a small grain cereal grass bearing coarse seeds, and since ancient times has been considered a valuable and nutritious grain. It includes jowar, bajra, ragi and small millets. Small millets include Barnyard millet, proso millet, kodo millet, little millet and foxtail millet. It is rich in fiber, protein, iron, calcium, magnesium, zinc, vitamin B, has a low glycemic index and has antioxidant, anti-inflammatory and anti-allergic properties (Ranjan et al., 2023). These have been added to the modern lifestyle as healthy foods because they are beneficial for human health due to the presence of nutritional ingredients. The nutritional quality of food is the most important parameter for maintaining human health and comprehensive physical health. Good nutrition is the driving force for growth and maximisation of human genetic potential (Radhila et al, 2011). Food quality in the diet must be considered to maintain optimal human health and fitness to address the deep-seated problem of malnutrition. Diversification of food production at both the national and household levels should be encouraged, in addition to increasing domestic productivity and technology (Singh and Raghuvanshi, 2016). Some agricultural foods are not used by humans as staple foods due to human ignorance. Millet is one of them. Millet is used as food for animals and birds. Millet has many nutritional and medical functions (Yang et al, 2012).

Introduction

Plant Parasitic Nematodes (PPN) belonging to the kingdom Animalia are considered the most serious threat to agriculture and horticulture crops worldwide. The estimated yield loss on average is about 173 billion USD (12.3%), among which developing countries are more prone to nematode infestation (14.46%) than developed countries (8.8%). Nevertheless, these PPN aggravate the loss by forming disease complexes with other soil-borne pathogens (Jones et al., 2013). PPN gain entry onto the host roots through their secretome which secretes various kinds of proteins that are mandatory for the expression of disease symptoms in host plants. These proteins are generally called Nematode-Associated Molecular Patterns (NAMPs). The management of nematodes through synthetic nematicides paves the way for the production of commodities with toxic residues that may have severe ill effects after consumption. However, the use of resistant plants is another strategy to combat major PPN and suppress their population in soil and roots. Recent research progress has revealed the various defence mechanisms exhibited by plants against the invasion of PPN. Here we will discuss in brief about the various mechanisms followed by the host plants to recognise the invading PPNs and the resulting host immune response in response to recognition of various effector proteins of PPN.
