Introduction

Knowledge of the avian respiratory system is essential for developing a health monitoring plan for a poultry flock, recognizing problems that may occur, and taking action to correct them. The avian respiratory system begins with nostril includes trachea, bronchi (bronchus) and ends with lungs and air sacs. Respiratory diseases are the most common cause of death in a poultry flock.

The avian respiratory system is involved in the following functions:

• Absorption of oxygen (O2)

• Release of carbon dioxide (CO2)

• Release of heat (temperature regulation)

• Detoxification of certain chemicals

• Rapid adjustments of acid/base balance

• Vocalization

Introduction

The digestive system of the birds has modifications to facilitate the easy flight. Length of intestine in birds is relatively shorter compared to mammals. Also, they lack teeth and jaw muscles which are replaced with light weight beak. Food grains are swallowed as whole and ground in the gizzard with the help of powerful muscles. In the mouth, tongue is used to manipulate the food and also aids in swallowing the food. Chickens have as many as 300 taste buds. The elementary system in birds consists of gastro intestinal tract and the accessory glands, the course of the elementary starts with Mouth, oesophagus, crop, proventriculus (glandular/true stomach), gizzard (mascular stomach), small intestine (duodenum, Jejenum, ileum), large intestine (colon and caeca) which lastly opens into cloaca. For fast growing poultry species elementary system is very important. It plays vital role in digestion, absorption and also provides protective immunity. Poultry intestines harbours diversified microflora which aids in enhanced availability of nutrients to the bird. Intestinal wall contains four layers: mucosal, submucosal, muscle tunic, and the serosal layer. As intestine is involved in important functions like digestion & immunity, any change in intestinal integrity / microflora balance impacts the bird performance in terms of body weight gain in broilers and egg number in layers. Some bacteria, viruses and also fungi produce different diseases / conditions in poultry birds. The ban on the use of antimicrobial growth promoters has pushed poultry producers from use of AGP’s to alternatives to AGP’s such as prebiotics, probiotics, essential oils and some herbals. Maintaining good gut health in the absence of AGP’s and anticoccidial drugs is a challenging situation for the poultry farmers across the globe. Poultry gut contains diverse community of bacteria, fungi, protozoa and viruses. The recent data suggests that gastrointestinal tract of a broiler chicken colonizes by an estimated 600 – 800 species of bacteria. The abundance and diversity of microbiota varies along the GI tract. After the hatch GI tract colonizes within 3-4 days. Small intestine of broilers mainly contains lactobacilli although enterococci, E.coli, eubacteria, clostridia, propionibacteria and fusobacteria can be found.

Introduction

In simple terms, business refers to buying and selling of products. Business would define itself as an organized effort through companies aimed at supplying consumers with products and services in a return for monetary compensation. However, this simplistic definition is insufficient to assess the impact of the environment on modern international business operations. For easy understanding, modern business can be explained as a complex field of industry and commerce involving activities associated with both production and distribution. These activities cater to the wants and desires of society at one extreme and provide profit for business firms at the other.

Indian leaders, particularly the first Prime Minister Dr. Jawaharlal Nehru, who had conceived the theory of five year plans, had regarded high economic growth and higher income among poor population as the foremost objectives before the newly independent nation. To achieve these objectives, government was made to play a very important role, and since 1951, a series of five year plans have been the driving forces behind the economic prosperity of the country. Despite of experiencing growth in 1950s, it was still lower than that of many Asian countries. Between 1951-79, the Indian economy had grown at an average rate of 3.1 percent a year at constant prices. Growth in the industrial sector had been about 4.5 percent a year, while for the agriculture sector, growth was 3.0 percent over that period. Many of the political leaders associated with the movement were also in support of a socialistic development pattern. They favored state interference in the economy. They encouraged state ownership of core industries.

Concept of Entrepreneurship

Entrepreneurship can be defined as the propensity of mind to take calculated risks with confidence to achieve a pre-determined business or industrial objectives. That points out the risk-taking ability coupled with decision making. The word ‘entrepreneurship’ typically means to undertake. It owes its origin to the western societies. But even in the west, it has undergone changes from time to time. In the early 16th century, the term was used to denote army leaders. In the 18th century, it was used to denote a dealer who buys and sells goods at uncertain prices. Towards 1961, Schumpeter, used the term innovator, for an entrepreneur. Two centuries before, the concept of entrepreneurship was shady. It is only in the recent years that entrepreneurship has been recognized widely all over the world like in USA, Germany, Japan and in the developing countries like ours. Gunnar Myrdal rightly pointed out that Asian societies lack entrepreneurship not because they lack money or raw materials but because of their attitudes. Till recently, in the west, the entrepreneurship is mainly an attribute of an efficient manager. But the success achieved by entrepreneurs in developing countries demolishes the contention that entrepreneur is a rare animal and an elusive character. In India the definition of an entrepreneur being the one who undertakes to organize, own and run a business has been accepted in a National Seminar on entrepreneurship organized in Delhi in 1975. Still there has been no consensus on the definition of entrepreneurship and qualities of entrepreneurship.

Plant diseases have been documented since ancient times. Fossil data suggests that plants were impacted by illness 250 million years ago. The Indian Vedic text and Bible refer to diseases like rusts, mildews, and blights that have led to famine and significant economic impacts throughout history. Plant pathology or Phytopathology (Greek Phyto-plant pathos- suffering or ailment; logos- knowledge/study/discourse) is a division of agricultural sciences focused on the examination of plant diseases. It encompasses the recognition, comprehension, prevention, and management of plant diseases caused by different pathogens as fungi, bacteria, viruses, nematodes, and other microbes. Plant pathology is the nature, cause and prevention of plant diseases. Plant disease refers to the physiological functioning of the plants that are irritated by prolonged, phytopathogenic organisms biotic or infectious disease causing agents and abiotic or non-infectious causes such as edaphic, environmental, plant nutrition etc. covered under disorders. Plant disease can also be defined as it is a malfunctioning process in plant body caused by continuous irritation induced by some causal agent that alters the physiology of the plants and results in some suffering or symptom production. It may be other way stated that it is a sum total of the altered and induced biochemical reactions in plant system or part brought about by any biotic, mesobiotic agents or abiotic factor leading to malfunctioning of biological processes and ultimately manifesting at cellular and/or morphological level.

In India, about 46 per cent of the milk produced is either consumed at the producer level or sold to non-producers in the rural area, the balance 54 per cent of the milk is available for sale to organized and unorganized players. The organized sector comprises of Government, Producers’ Owned Institutions (Milk Cooperatives & Producer Companies), and Private players which provides a fair and transparent system of milk collection round the year at the village level. The unorganized/informal sector involves local milkmen, dudhias, contractors, etc. and they are mostly found to be opportunistic, as there is no uniformity of milk price paid to producers and it varies depending upon the situation. The possibility of adulteration of milk is higher among these unorganized groups. In the areas where competition is high and the presence of the formal sector is strong, the unorganized sector generally gives higher prices and at the same time, the unorganized sector doesn’t offer remunerative prices to the producers where the organized sector is not present.

Introduction

Millets, which are small-seeded grasses belonging to the Poaceae family, have a rich historical and cultural significance as they have been cultivated for thousands of years (Goron and Raizada, 2015; Wen et al., 2014; Cheng, 2018). They remain an important crop in various regions worldwide, particularly in developing countries where they serve as a staple food for millions, especially in rural areas. Millets offer several advantages as they are gluten free and provide valuable protein, fiber, and minerals, making them highly nutritious for both human consumption and animal feed. The diverse range of millets includes pearl millet (Cenchrus americanus (L.) Morrone), foxtail millet (Setaria italica (L.) P.Beauv.), proso millet (Panicum dichotomiflorum Michx.; syn. Panicum miliaceum Walter), finger millet (Eleusine coracana (L.) Gaertn.), barnyard millet (Echinochloa frumentacea Link), kodo millet (Paspalum scrobiculatum L.), little millet (Panicum sumatrense Roth), and more (Ahmad et al., 2018; Bora et al., 2019). These grains have a significant historical presence globally, with evidence of cultivation in ancient China, Greece, and Rome (Li et al., 2020a; Huan et al., 2022). In India, millets have maintained their importance as a vital crop for thousands of years and continue to be an integral part of the diet in many regions of the country today (Padulosi et al., 2015; Li et al., 2020b).

Management of Other Avian Species

Duck

Overview

• Asia: The homeland of ducks.

• Global Rankings: China holds the first position in duck population, followed by India.

• Significance in India: Ducks are the second most important poultry species, constituting about 10% of the total poultry population (851.82 million) and contributing 6-7% of the total egg production (138.38 billion) in the country (BAHS, 2024).

BERSEEM CLOVER (Trifolium alexandrinum)
Fungal diseases
i) Damping-off
Symptoms
Pre-emergence damping-off: Seeds decay inside the soil.
Post-emergence damping-off: Sometimes after germination water-soaked blighted seedlings develop. Seedlings collapse and wilt. Stem and root tissues rot below the soil surface.
Causal organism
i) Pythium spinosum var. spinosum
ii) Rhizoctonia solani
Favourable condition
i) Promoted by high humidity
ii) Poor air circulation.

Macaroni: Thick hollow tubes of pasta which are usually short and curved.
Macaroons: Small chewy cakes or cookies made from ground almonds/almond paste or coconut, sugar and egg whites. It is ften baked on rice paper.
Maceration: Softening or breaking up of foods by soaking in a liquid, or the soaking of foods (usually fruits) in a liquid in order to absorb the flavour. Spirits or liqueurs are often used as the macerating liquid.
Machine vision: Inspection systems in which samples are examined using a camera, the image from which is analysed by computer using image processing algorithms. Operations which can be performed include defect detection, dimensions measurement, orientation detection, grading, sorting and counting.
Magnesium (Mg): One of the essential mineral nutrients which is widely distributed in plant and animal foods, good sources including fruits, vegetables and dairy products. Standard Western diets generally contain adequate levels of magnesium, so fortification is largely unnecessary. Absorption of dietary magnesium may be affected by other dietary nutrients such as calcium, phosphate and vitamin D, and also by some clinical conditions, including alcoholism and diabetes. Magnesium is an important bone constituent and intracellular inorganic cation acting as an essential cofactor in many enzymic reactions. Magnesium deficiency can cause calcification of soft tissues, electrolyte imbalances, gastrointestinal symptoms and personality changes. If taken in excess, magnesium toxicity symptoms can include nausea, vomiting, hypotension and neurological changes.

India is known as the land of spices, while Kerala is often referred to as the spice bowl of the country. Out of the 109 spices acknowledged by the International Organization for Standardization (ISO), India cultivates around 63 spices. The Spices Board of India actively encourages the cultivation and trade of 52 spices. This remarkable diversity in spice cultivation is made possible by India’s varied geographical conditions, encompassing all 15 agroclimatic zones, ranging from tropical and subtropical to temperate regions. These diverse conditions enable the cultivation of almost all kinds of spices.
Definition
Spices are defined as “spices are those plants, the plant products of which are made use as food adjuncts to add aroma and flavour”. Spices are also defined as per the Internal Organization for Standardization (ISO) as “Spices are Vegetable products, or mixtures thereof, free from extraneous matter, used for flavouring, seasoning and imparting aroma to foods”.
Condiments are defined as “condiments are also spices, products of which are used as food adjuncts to add taste only.” Mainly used for seasoning purpose. Herbs are defined as “dried leaves of aromatic plants used for flavouring food”. Both spices and condiments consist of essential oils which enhance the flavour and taste.

Abstract
India faces a shortfall of 10 million tonnes in vegetable production against a demand of 135 million tonnes, exacerbated by extreme temperatures (5-48°C) that hinder year-round cultivation. Protected cultivation, including greenhouses, polyhouses, and shade nets, offers a solution by enabling off-season vegetable production, enhancing yield, quality, and input efficiency. In regions like Bundelkhand, where agriculture dominates the economy, low-cost protected structures have shown promise in cultivating high-value crops like tomatoes and capsicum, despite challenges such as farmer unawareness, limited capital, and poor infrastructure. Government initiatives, like those by Banda University of Agriculture and Technology, promote low-cost protected cultivation through training and infrastructure development, fostering agripreneurship and improving rural livelihoods by increasing yields and market prices.

1. No Tillage (No Ploughing or Turning of the Soil)
• The principle of No Tillage in natural farming refers to the practice of avoiding the mechanical disturbance of the soil, such as ploughing, turning, or tilling. This approach is central to natural farming because it allows the soil to maintain its natural structure, preserves its biodiversity, and enhances its ability to support plant growth sustainably.
• Tillage disrupts the natural layers of the soil. When the soil is left undisturbed, its structure remains intact, allowing for better water infiltration, root penetration, and nutrient availability. A well-structured soil is more resilient to erosion and compaction.
• Soil is home to a vast network of microorganisms, including bacteria, fungi, and earthworms, that play crucial roles in nutrient cycling and plant health. Tilling can destroy these delicate ecosystems, reducing the soil’s fertility. No tillage preserves these beneficial organisms, promoting natural soil regeneration.
• In natural farming, organic matter (like dead plants, mulch, and crop residues) is left on the surface of the soil. As it decomposes, it contributes to the formation of humus, a rich organic material that improves soil fertility and helps retain moisture. Tillage disrupts this process, speeding up the decomposition of organic matter and reducing its long-termbenefits.
• No tillage improves the soil’s ability to absorb and retain water, which reduces the need for irrigation and helps crops withstand drought conditions. Additionally, undisturbed soil is more resistant to erosion because plant roots and soil structure act as a barrier against wind and water erosion.

Introduction
Management of abiotic stresses in fruit orchards are essential and key issue for sustaining productivity. Worldwide fruit consumption has increased significantly because of the new recognitions of its broad relevance for health, nutrition and livelihood (Lansky and Newman, 2007). Fruits like pomegranate, grapes, dragon fruit, mango and sapota are being grown in tropical humid to dry as well as arid and semi-arid climates of India, especially in states like Maharashtra, Karnataka, Tamil Nadu, Andhra Pradesh, and Gujarat. Significant cultivars such as Bhagwa of pomegranate, Hapus, Kesar, Langra, Banganpalli, Totapuri of mango and Kallipati, Cricket ball of Sapota are being dominantly grown in these areas. Area under pomegranate was 2.62 lakh ha in 2018-19, producing 30.04 lakh MT at a productivity of 11.58  ha-1 with an export of 80.5 thousand MT during 2019-20 (Maity et al., 2020). The estimated area under grapes, mango, pomegranate and sapota in India is 0.14, 2.29, 0.26, 0.08 million ha, respectively whereas production estimates are reported to be 31.25, 204. 44, 23.15 and 10.03 million MT, respectively (NHB 2019-20 2nd estimate). Besides area of dragon fruit in India is rapidly expanding due to its high nutritional content, antioxidant properties, and market opportunities, covering around 20 thousand ha with annual production of 0.3 million MT. Despite the fact that >15 species of Hylocereus have been reported; only 3 to 4 are under cultivation. Among these, white flesh (H. undatus) occupied more than half of the area. However, the current premium pricing and consumer demand for pink flesh may shift cultivation to H. polyrhizus. Furthermore, species with yellow peel and white flesh (H. megalanthus) is now being cultivated. In this context, the issuances of agro-advisory services to farmers are essential for adopting time bound management protocols (Adak et al.,2018a). The importance of this scientific management is significantly linked with the fruit business both in domestic market and foreign export. Therefore, it is of great importance for advisory, training, farmers-scientific interaction and other human resource management programmes to sensitize and develop trained man power sufficiently which contributes to the horticultural growth and development. In this backdrop, fruit orchards and their scientific management is discussed in this chapter with special reference to abiotic and biotic stress management in Pune region of Maharashtra.

Introduction
Spices have been considered significant in the culinary art from time immemorial. India, “The Homeland of Spices” is one among the largest producers, consumers and exporters of spices as well as spice products. Spices comprise different plant components such as floral parts or fruits or berries or seeds or rhizomes or roots or leaves or kernel or aril or bark or bulbs. The recorded history of the use of spices dates back to 5000 years or so from the Egyptian or at the most from the Indus valley civilization. Spices are used for flavouring, seasoning and imparting aroma in various cuisines. Besides these inherent qualities, some of them are known to be fungistatic, antimicrobial or antibiotic. They are also processed into numerous ‘value added’ products such as oleoresins, essential oils, curry powder etc. Black pepper, cardamom and turmeric are the major spice crops and its production and marketing are the main economy stays of lakhs of people of the country. Billions of rupees are involved in domestic trading and foreign export. Therefore, it is highly imperative for farmers to adopt the advanced practices to sustain spices productivity. Even, additional income could be generated from the intercropping of spices from the interspaces in mango orchards (Shukla and Adak, 2020). Thus the present chapter included all aspects of production to protection and value addition for  the benefits of growers.

The perennial nature of fruit crops coupled with high heterozygosity, protracted juvenility, and lack of information on inheritance patterns of important traits of economic significance is responsible for slow progress in breeding of fruit crops. Citrus is one of the most popular fruit crops cultivated in around 140 countries of the world mainly in the Asia-Pacific region. In Asia, citrus fruits are a major crop for the local people in meeting their nutritional requirements and livelihood. Citrus is cultivated as an indispensable cash crop both for domestic consumption and the export market. Recently, the citrus production has shown an increasing trend mainly attributed to its increased demand as a nutritious and healthy drink owing to the possession of many medicinal and antioxidant properties in its fruits.
The clonal selection has been used primarily as one of traditional breeding methods because bud sport mutations arise frequently in Citrus (Iwamasa et al., 1981; Uzun et al., 2004). This method of breeding generally offers many advantages to select clones suitable for their identified uses. Yield and fruit quality are the major targets of breeding and both these can be enhanced through clonal selection of natural mutants or seedlings. The major aim of the clonal selection studies is the selection of clones bearing regularly for many years, improved fruit appearance and tolerance to biotic and abiotic stresses. In general, identifying the elite clones, testing them under different climatic conditions, and freeing them from the virus and virus-like pathogens carried by the mother plants are major steps involved in clonal selection (Ulubelde et al., 1986) for the improvement of fruit crops.

Brinjal is the fifth most economically important Solanaceous crop after potato, tomato, chilli, and tobacco. Apart from the well-known brinjal species (Solanum melongena L.), two other under-utilized species, the scarlet eggplant (S. aethiopicum L.) and the gboma eggplant S. macrocarpon are also cultivated. Brinjal, also known as aubergine or eggplant, under the family Solanaceae (Chromosome No.: 2n = 2x =24) is one of th important vegetables of the tropical countries particularly India, Bangladesh, Pakistan, China, Japan, Indonesia, Thiland, Malaysia and the Philippines. Brinjal is the most common, popular and principal vegetable crop grown widely in India for its various shape, size and colour of fruits. Brinjals are rich sources of potential antioxidants: anthocyanin and phenolic compounds.
Origin, domestication and adaptation in India
Brinjal (Solanum melongena) is believed to have been originated in Indo-Burma region and perhaps China is the secondary centre of origin of this crop. Various data indicate, that from the several species that evolved in Africa, one (S. insanum), gave rise to a distinct species which spread to South-East Asia as the wild ancestor of S. melongena (Lester 1998; Ranil et al., 2017). This wild progenitor of the cultivated species has wide distribution in at least 10 habitats in India which amply suggests India being the centre of origin of brinjal.

Brinjal (Solanum melongena), also known as eggplant or aubergine, is a major solanaceous vegetable crop grown in India and other parts of the world. It is affected by several insect pests throughout its growth period, significantly reducing both yield and quality.
Introduction
One of the major constraints in production and productivity of brinjal is the incidence of pests and diseases. The fruit and shoot borer is one of the most damaging pests of brinjal. Pest infestation starts from transplanting seedling stage and continues up to harvesting of the crop. Pest is active throughout the cropping season with peak infestation from last week of August to December
Distribution
China, India, Bangladesh, Malaysia, Thailand, Burma, Sri Lanka, Laos, Congo and South Africa

Introduction
Eye
Visual perception, eyesight, sight, or vision is the ability to interpret the surrounding environment using light in the visible spectrum reflected by the objects in the environment. The eyes are the sensory organs that are extension of the brain; they receive visual information from the environment and transmit them to the visual sensory area of the brain for interpretation.
The pineal and para-pineal glands are photoreceptive in non-mammalian vertebrates. Birds have photoactive cerebrospinal fluid (CSF)-contacting neurons within the paraventricular organ that respond to light in the absence of input from the eyes or neurotransmitters.
Accessory Structure of the Eye
Eyelids - (Palpebrae) The free margins of the eyelids form the palpebral fissure. The edges where the upper and lower eyelids meet are called the lateral and medial canthus. The palpebral margins are lined by eyelashes. The eyelids are supported internally by sheets of connective tissue that form the tarsal plate.
Glands associated with the eyelids
Glands of Zeis - These are sebaceous glands associated with the eyelashes.
Tarsal glands - (Meibomian glands) - These glands line the inner margin of the lid and
produce a lipid-rich product that prevents the lids from sticking together.
Lacrimal caruncle - This is a mound of tissue in the medial canthus that produces thick secretions.
Conjunctiva It is the epithelium that lines the inner surface of the eyelids and continueson to the outer surface of the eye.
Palpebral conjunctiva lines the inner surface of the eyelid.
Bulbar conjunctiva lines the anterior surface of the eye.
Lacrimal Apparatus It produces, distributes and removes tears. Tears reduce friction, remove debris, prevent bacterial infection and provide nutrients and oxygen for the conjunctiva. Lacrimal glands are located near the lateral canthus of the eye. Tears flow over the cornea and are drained into the nose by the nasolacrimal duct.

Introduction
The haematological system, essential for sustaining life and comprising blood and its components, is fundamental to human and animal physiology. Blood is a unique connective tissue that performs several critical functions, including transporting oxygen, nutrients, and hormones to cells and removing metabolic wastes. It also plays a pivotal role in immune response, haemostasis, and the regulation of body temperature and pH. This
section provides an in-depth overview of the clinical physiology of the haematological system, covering the composition of blood, haematopoiesis, haemostasis, and common haematological disorders. Blood is composed of two main elements: plasma and blood cells. Plasma, the liquid component, constitutes approximately 55% of blood volume and consists predominantly of water, electrolytes, proteins, waste products, and dissolved gases. Plasma is the medium for transporting nutrients, gases, hormones, and waste products throughout the body. It contains important proteins such as albumin, which maintains osmotic pressure; globulins, which are involved in immune responses; and fibrinogen, which is crucial for blood clotting. The blood cells include erythrocytes (red blood cells), leukocytes (white blood cells), and platelets. Erythrocytes are the most abundant cells in the blood, with the primary function of transporting oxygen from the lungs to tissues and carbon dioxide from tissues back to the lungs. This is facilitated by haemoglobin, an iron-containing protein within erythrocytes that binds to oxygen. The lifespan of an erythrocyte is approximately 120 days, after which it is phagocytosed by macrophages, which are a type of myeloid phagocytic cells in the spleen and liver. Leukocytes are integral to the immune system, protecting the body against infections and foreign pathogens. They are categorized into granulocytes (neutrophils, eosinophils, and basophils) and agranulocytes (lymphocytes and monocytes).

Abstract
The growing global population has intensified farming practices, increasing the use of fossil fuels and agrochemicals. With limited land and the need to enhance food production, balancing environmental impact, especially carbon footprints, is crucial. Climate-smart mitigation options, with a prime emphasis on crop diversification, can help agriculture adapt to anomalous weather patterns and build resilience. Legumes offer a sustainable solution by reducing greenhouse gas emissions, as they produce 5-7 times less gases per unit area compared to other crops. They aid in carbon sequestration, with soil carbon estimates of 7.21 g kg-1 of dry matter, and save fossil energy by decreasing nitrogen fertilizer use, reducing CO2 emissions by 277 kg ha-1 per year. Legumes play a key role in low-emission farming systems due to their ability to fix atmospheric nitrogen, reducing dependence on energy-intensive synthetic fertilizers. They improve soil health, enhance soil structure, and support carbon sequestration. Integrating legumes into crop rotations reduces the need for chemical pesticides and fertilizers. Additionally, legumes can be used in food, feed, and biofuels, lowering reliance on more carbon-intensive resources. Embracing legumes in farming systems promotes sustainability improves soil health, and considerably reduces the overall environmentalimpact of agriculture.

4.1 Introduction
Human milk widely acknowledged as the optimal source of nutrition for infants, providing a rich array of components crucial for their growth, repair and development. However, the composition of human milk can vary
significantly within and between feeds, throughout the day, over the course of lactation, and among different mothers and also populations. While this variability is beneficial for infant health and survival, it presents challenges for the management of nutrition of high-risk infants who require precise oversight. The composition of human milk can be altered by factors such as the handling of expressed milk, including how it is stored and pasteurized. Thus, proper management of expressed milk is essential. The recommended practice for infant nutrition is exclusive breastfeeding for the first six months, followed by continued breastfeeding for at least one to two years. Human milk is naturally suited to meet the nutritional needs of infants, providing both nourishment and bioactive compounds that support healthy growth and immunity.
Human milk contains a variety of bioactive components, such as immune cells, anti-infective and anti-inflammatory agents, growth factors, and prebiotics. In contrast to infant formula, which has a fixed nutritional profile, human milk is dynamic and can vary between and within feedings, influenced by maternal factors, environmental conditions, and the methods used for expressing and managing milk.
A thorough understanding of human milk’s composition is vital for effective infant feeding, especially for at-risk infants. It also allows for the assessment of how milk storage and pasteurization may impact its beneficial components. Additionally, some of the bioactive elements in human milk are being studied for their potential use in medical treatments, either as preventive or therapeutic agents.

Importance of Policies for Extension
Policies play an important role in the field of extension, which involves the transfer of knowledge and technology from researcher to farmers, communities and other stakeholders. Following are some specific reasons why policies are vital for extension:
1. Accountability: Policies may provide basis for monitoring and evaluation of extension activities and for holding extension professionals and other stakeholders accountable for their actions.
2. Innovation: Policies can promote innovation in extension by encouraging the adoption of new technology, approaches and practices, encouraging experimentation, collaboration and continuous improvement. By removing barriers to adoption and offering rewards for testing, policies can also aid in the creation of an atmosphere that fosters innovation.
3. Consistency: Policies aid in ensuring that extension activities are consistent with the goals and objectives of organization or program. It offers a framework for decision-making that enables the uniform
handling of similar circumstances.

Prevalent Farming Systems in India Contributing to Livelihood India has a diverse range of farming systems, shaped by agro-climatic zones, socio-economic conditions, and cultural practices. India, with its diverse agroclimatic zones and socio-economic conditions, supports a variety of farming systems that play a crucial role in providing food, income, and employment to a large segment of the rural population. These systems vary by region, resource availability, landholding size, and climatic conditions, and are vital in ensuring sustainable livelihoods for millions of small and marginal farmers.
Here are some prevalent examples:
• Rice-Wheat System: Predominant in the Indo-Gangetic Plains. It involves rotating rice in the wet season and wheat in the dry season. This system is crucial for food security but faces challenges related to water depletion and soil degradation.
• Rainfed Farming Systems: Found in arid and semi-arid regions. Farmers rely on rainfall for crop production. Common crops include millets, pulses, and oilseeds. Drought-resistant varieties and water conservation techniques are essential.
• Mixed Farming Systems: Integrate crop production with livestock rearing. This system is common across India and provides multiple income streams. Livestock provides manure for soil fertility and draught
power, while crops provide feed for animals.
• Horticultural Systems: Focus on the production of fruits, vegetables, and flowers. These systems are often found in regions with favorable climate and access to markets. They can generate high incomes but
require significant investment and management skills.
• Plantation Systems: Involve the cultivation of cash crops like tea, coffee, rubber, and spices. These systems are concentrated in specific regions with suitable agro-climatic conditions.

Preservation of raw milk is essential to maintain its quality during storage and transportation before processing. One of the primary methods for extending its storage life is refrigeration, where milk is cooled to 2°C to 4°C immediately after milking. This significantly slows down the microbial growth and enzymatic activity. Bulk milk coolers (BMCs) are vital in achieving rapid cooling, especially in collection centres or dairy farms, where they ensure that milk remains fresh during storage and transportation. BMCs are particularly essential for regions with inadequate cold chain infrastructure, as they help maintain milk quality until it reaches processing facilities.
In addition to refrigeration, thermisation is another method used to preserve raw milk. Thermisation, a mild heat treatment, is widely used to extend the shelf life of raw milk, particularly when it needs to be transported over long distances. This process involves heating the milk to 57–68°C for 15 seconds, effectively reducing the microbial load while preserving the milk’s natural characteristics. Thermisation is typically followed by refrigerated storage, where milk is cooled to temperatures between 2° and 4°C to inhibit further microbial growth. The combination of thermisation and refrigeration ensures that milk retains its freshness and safety until it reaches processing facilities, even in regions with extended supply chains.
Raw milk also benefits from its natural inhibitors, such as lactoperoxidase, lactoferrin, and immunoglobulins, which exhibit antimicrobial properties and slow down bacterial growth. The lactoperoxidase system, for instance, can be activated by adding small amounts of hydrogen peroxide and thiocyanate to enhance milk’s preservation in the absence of refrigeration. The use of chemicals like hydrogen peroxide (H2O2) for milk preservation is not permitted in India due to safety and quality concerns. However, the FAO recommends its application under strict regulatory conditions in some countries as part of the lactoperoxidase system, particularly in regions where refrigeration is unavailable.

Maintaining a proper acid-base balance is crucial for the health, productivity, and survival of livestock and poultry. The physiological processes that regulate this balance are sensitive to various factors such as diet, environmental conditions, and metabolic disorders. Any disruption can lead to metabolic problems that negatively impact growth, reproduction, immunity, and overall performance. The acid-base balance in animals refers to the maintenance of the blood’s pH within a narrow range, typically 7.35–7.45. It is regulated by three main systems:
Buffer systems
The bicarbonate buffer system is the most significant, comprising bicarbonate ions (HCO3 –) and carbonic acid (H2CO3). It resists rapid pH changes by neutralizing excess acids or bases.
Respiratory regulation
Animals adjust blood pH by modulating the rate and depth of respiration, which affects carbon dioxide (CO2) levels. Increased CO2 leads to acidosis, while decreased CO2 causes alkalosis.
Renal regulation
The kidneys excrete hydrogen ions (H+) and reabsorb bicarbonate, playing a long-term role in maintaining acid-base homeostasis.
Disruptions in these systems can lead to two primary conditions: Acidosis: A state where the blood becomes too acidic (pH < 7.35).
Alkalosis: A condition where the blood becomes too basic (pH > 7.45).
Common metabolic problems.

India’s diverse climate and geography provide a favorable environment for growing a wide range of fruit-type vegetables, including eggplant, tomato, okra, and chillies. These crops are not only essential for food security but also contribute significantly to the country’s agricultural economy. To optimize the production and productivity of these crops, it is crucial to understand their agroclimatic requirements.
Fruit-type vegetables have specific temperature requirements for growth and development. For instance, eggplant and okra require warm temperatures between 20-30°C (68-86°F) for optimal growth, while tomatoes prefer a slightly cooler temperature range of 15-25°C (59-77°F). Chilli peppers, on the other hand, thrive in temperatures between 20-35°C (68-95°F). Adequate moisture is also essential for the growth and development of fruit-type vegetables. Eggplant, okra, and chilli peppers require consistent moisture, especially during the fruiting stage, while tomatoes require a slightly drier soil condition. The ideal annual rainfall for these crops ranges from 600-1,200 mm, with supplemental irrigation provided during periods of drought.
Weather conditions, such as sunlight, wind, and frost, also play a crucial role in the growth and development of fruit-type vegetables. Most fruit-type vegetables require full sun to produce well, while excessive wind can damage plants and reduce yields. Frost, on the other hand, can be detrimental to these crops, and frost-free periods are essential for optimal growth. India‘s diverse
climate and geography result in regional variations in agroclimatic conditions. For instance, the Indo-Gangetic Plains, which cover parts of Uttar Pradesh, Bihar, and West Bengal, have a subtropical climate with hot summers and cold winters. In contrast, the Deccan Plateau, which covers parts of Maharashtra, Karnataka, and Telangana, has a tropical climate with warm summers and mild winters. Understanding these regional variations is essential for optimizing the production and productivity of fruit-type vegetables. The agroclimatic conditions suitable for growing different fruit type vegetables are given in this chapter.

Beans play a vital role in India’s agricultural sector and food security. They are an essential source of protein, fiber, and other essential nutrients, making them a crucial component of the Indian diet. Beans are also a significant source of income for many farmers in India, particularly small and marginal farmers. The country’s bean production also contributes significantly to the national
economy, with India being one of the largest producers of beans in the world. In addition to their nutritional and economic importance, beans also play a crucial role in maintaining soil fertility and promoting sustainable agriculture practices in India. Beans are legumes, which mean they have the ability to fix nitrogen in the soil, reducing the need for synthetic fertilizers and promoting
soil health. India is a significant producer of various types of beans, which are widely used as vegetables in the country. These beans are not only a good source of protein, fiber, and other essential nutrients but also play a crucial role in the country’s agricultural sector.
Overall, beans are a vital crop in India, and their production and consumption play a significant role in the country’s food security, agricultural sector, and national economy.
They are grown in various parts of the country, with major production areas including Punjab, Haryana, and Uttar Pradesh. According to the Indian Ministry of Agriculture and Farmers Welfare, the country produced over 1.4 million metric tons of kidney beans in 2020-21. Kidney beans are an essential ingredient in many popular Indian dishes, such as rajma masala, and are also used in salads, soups, and stews.

Introduction: Relation between transportation and meat quality
One of the fundamental aims of animal production system is to ensure better quality meat. Apart from various animal husbandry practices that affect the meat quality, the transportation of meat animals from farm to slaughterhouse and their handling at lairage, affect the meat quality greatly. For better meat quality, the pH of the meat should fall from normal pH 7.0 - 7.2 in live animal to pH 5.5 (ultimate pH) after slaughter at the onset of rigor-mortis. The low muscle pH is required to inhibit the microbial growth and meat tenderization (cathepsins system is activated at low pH). The ultimate muscle pH is achieved through the accumulation of lactic acid which is produced as a result of anaerobic glycolysis of glycogen. After slaughter, as the oxygen supply to muscle ceases, ATP is generated through anaerobic glycolysis of glycogen and in this process lactic acid is produced. ATP is required to keep the muscle in relaxed stage. This anaerobic glycolysis carries on till the glycogen reserve is exhausted. So, higher the glycogen reserve at the time of slaughter, longer the length of time duration of anaerobic glycolysis and higher the quantity of lactic acid production and greater the reduction of muscle pH. Hence, livestock should be transported and handled before slaughter carefully because stress during transit and in lairage could severely deplete the glycogen reserve of livestock.
The following facts should be especially taken care by the farmers raising livestocks for meat
1. Housing arrangement and design
• Any flaws/deficiencies in design, layout, cubicle size and its design, drainage, water bowls, slats, air circulation, etc. should be rectified

Earth’s atmosphere is a dynamic and complex system that plays a crucial role in supporting life as we know it. This chapter explores into the fascinating world of this gaseous envelope that surrounds our planet, exploring its composition, structure, and the processes that drive both our daily weather and long-term climate. It includes:
• Composition and Structure: It will begin by examining the unique blend of gases that make up the atmosphere, including nitrogen, oxygen, argon, and trace amounts of others. It will also be explored how the atmosphere is structured into distinct layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere), each with its own characteristics and role.
• Weather: Weather refers to the short-term conditions of the atmosphere at a specific time and place. We’ll discuss the key elements of weather, such as temperature, pressure, humidity, wind, and precipitation, and how they interact to create the ever-changing weather patterns we experience.
• Climate: In contrast to weather, climate describes the long-term average of atmospheric conditions in a particular region. We’ll investigate the factors that influence climate, including latitude, altitude, proximity to oceans, and atmospheric circulation patterns. We’ll also explore the different climate zones found across the globe.
• Interconnectedness: A key focus of this chapter understands how weather and climate are interconnected. Daily weather patterns are influenced by the same fundamental atmospheric processes that shape long-term climate. For example, the way the sun’s energy interacts with the atmosphere drives both daily temperature variations and global climate patterns.

The history of digestion experiments dates back to the mid-19th century when the first true trials were carried out at the Weende Experiment Station in Germany. In 1858, researchers Henneberg and Stohmann began their experiments and published their findings in 1860, which condemned Thaer’s hay equivalents and gave results of their experiments. These trials coincided with the chemical analysis of feedstuffs at the Weende station. Even before 1860, studies on nutrient losses in feces had been conducted to calculate TDN (total digestible nutrients). Over time, numerous publications have recorded the results of digestion experiments, with Schneider and Flatt (1975) documenting more than 3000 studies. In India, over 430 digestion trials have been conducted with Indian feeds and fodders at various research stations, as published by ICAR. The wealth of information gathered from these experiments has greatly advanced our understanding of digestion processes and has enabled improvements in animal nutrition practices.
Digestibility
Nutrients in feed are not fully utilized by livestock, with a significant portion being excreted in feces due to incomplete digestion in the digestive tract. Digestibility can be defined as the proportion of nutrients that are absorbed by the animal’s body and not excreted. It is essential for the animal’s growth, reproduction, and overall metabolism. Animals fed highly digestible feed show improved growth and reproductive performance, leading to increased market availability.
The formula for calculating digestibility is simply the difference between nutrients in the nutrient consumed and nutrients found in faeces.
Digestibility = Nutrients in forage – Nutrient in faeces

The profitability of dairy animals depends on milk yield and reproductive efficiency. High-yielding cows require more nutrients to support increased milk production. However, early lactating cows and buffaloes often face a Negative Energy Balance (NEB) due to inadequate energy intake, which hampers their performance. To enhance productivity, it is essential to minimize the extent and duration of NEB. One effective approach is the use of bypass nutrients, which safeguard essential dietary components like fat and protein from rumen fermentation, enabling better digestion and absorption in the lower digestive tract. Additionally, protected starch, chelated minerals, and vitamins can also boost animal performance.
“Bypass Nutrients” are nutrients that undergo minimal fermentation in the rumen, allowing them to remain intact for digestion and absorption in the lower gastrointestinal tract. These slowly degradable nutrients provide a steady nutrient supply to rumen microbes, unlike easily soluble nutrients that lead to sudden spikes in nutrient availability.
Rationale behind the protection of dietary nutrients
The potential benefits of delivering nutrients directly to the intestine in a form available for direct absorption and utilization by the animals are:
1. Prevention of energy losses associated with the degradation and fermentation of nutrients in the rumen, thus sparing available energy for productive purposes.
2. Ensuring that particular nutrients will be available to the host animal in their original form.
3. Taste masking of unpalatable substances.
4. Preventing interactions among nutrients and their oxidation during storage.

1. Introduction
Aquaculture is a rapidly expanding industry, playing a crucial role in addressing the global demand for high-quality protein sources as wild fish stocks face depletion. With aquaculture production on the rise, ensuring the health and productivity of farmed fish has become increasingly important. The health of the fish gut is central to achieving these objectives, as the gut is responsible not only for nutrient digestion and absorption but also for maintaining a strong immune defense. A well-functioning gut leads to better growth performance, reduced disease susceptibility, and improved overall fish welfare.
However, maintaining optimal gut health in aquaculture systems presents challenges. The intensive nature of fish farming can lead to stressors that compromise the gut environment, including changes in water quality, fluctuating diet compositions, and exposure to pathogens. Gut health issues often manifest in poor feed conversion ratios, slower growth, and higher mortality rates, all of which negatively impact aquaculture productivity and sustainability. Therefore, there is a growing focus on finding innovative and natural solutions to improve the gut health of farmed fish.
In recent years, the use of probiotics and prebiotics in fish nutrition has gained significant attention as an effective and eco-friendly strategy to modulate gut microbiota and enhance fish health. These functional feed additives are considered a natural alternative to antibiotics and other pharmaceuticals, which have historically been used to manage diseases and promote growth in aquaculture but come with risks of antibiotic resistance and environmental contamination.

This chapter reviews the research work done in the fields related to the objectives of the study.

2.1. Ecosystem Services and Conservation Agriculture
Acharya, S. K. and Chatterjee, R. (2019) found that conservation agriculture may help in re-building agro-ecology by maintaining carbon sequestration, maintaining soil health, checking soil erosion and ground water depletion, energy balance, mitigating climate change related problems through maintaining ecosystem services.
Ayyam, V., Palanivel, S., and Chandrakasan, S. (2019) stated that CA embraces higher rates of carbon sequestration, organic matter accumulation, soil erosion reduction, and its associated improvement in soil biological properties. Additionally, there is reduction in greenhouse gas emission as a result of CA. Adoption of CA-based farming practices particularly in areas facing notable land degradation and depleting natural resources delineates a win-win scenario due to improved crop yield and trends of increasing soil fertility and scope for climate change adaptation to recuperate degraded soils and improve ecosystem services.

DSM-5 and Diagnosis of Mental Health Issues
Mental health is a fundamental aspect of overall wellbeing and the accurate diagnosis of mental health issues is crucial for providing appropriate and effective treatment. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) is the latest reference guide used by mental health professionals to diagnose mental health conditions (Kapadia et al., 2020). The current edition, DSM- 5, builds on the goal of its predecessors of providing guidelines for diagnoses that can inform treatment and management decisions. The DSM-5 provides a comprehensive and standardized framework for the classification and diagnosis of mental disorders.
The DSM-5 represents a significant advancement in the field of psychiatry, as it incorporates a cross-cultural assessment of mental health issues and an updated classification system. (Petito et al., 2020) This detailed diagnostic criteria helps clinicians accurately identify and differentiate mental health conditions, enabling them to develop tailored treatment plans.
