Mastitis

Mastitis is an economically important disease of dairy animals (cows and buffaloes) caused by a wide variety of pathogens (bacteria, some viruses, fungi).Major pathogens are Streptococcus agalactiae, Staphylococcus aureus, E. coli, Streptococcus uberis, Str. Dysagalactiae, Campylobactor, Corynebacterium pyogenes, Klebsiella spp. Pasteurella, Pseudomonas, Mycoplasma, Enterobactor, Trichosporon spp., Aspergillus fumigatus, Candida spp., Leptospira spp. and many more. Mastitis is also seen in lactating goats and sheep. As compared to ruminants mastitis is less common in bitches. Mastitis is an inflammatory disease of the udder parenchyma irrespective of its etiology. The disease occurs in clinical and subclinical forms. Clinical mastitis is of two types viz. acute mastitis and chronic mastitis. Subclinical mastitis is characterized by an increased number of somatic cells (>100,000 cells/ml) and/or pathogens in the milk with no apparent clinical change in the udder and milk. While clinical mastitis is associated with local (hot, pain full swelling of the udder) and general symptoms along with change in milk (increased cell count, increased pathogens, physical and chemical changes in the milk).

Definition

• Aetiology is defined as study of causation of disease.

Classification of Causes

• There are several agents or factors that can produce diseases in animals and can originate from within the body (intrinsic) or outside the body. (extrinsic).

Causes are classified into two categories

1. Predisposing causes (Intrinsic/Endogenous factors)

2. Definitive causes (Extrinsic/Exogenous factors)

Predisposing Causes

• Make the animal susceptible to definitive causes.

French bean (Phaseolus vulgaris L.) is a nutritious protein-rich legume vegetable crop cultivated in all parts of the world except Antarctica. Immature pods are consumed as vegetables, and matured pods are used as grain legumes (Allem, 2013). French bean is cultivated in 1.65 million hectares of area with a production of 26.98 million tonnes and productivity of 16.36 tonnes per hectare for vegetable purposes. As a grain legume, French bean was cultivated in 33.02 million hectares with a production of 28.90 million tonnes and productivity of 874.1 kg/ha during 2019 globally. In India, French bean is grown in 2.56 lakh hectares for vegetable purposes and 126.91 lakh hectares for grain legume purposes with a production of 7.26 lakh tonnes as immature pods and 53.10 lakh tonnes of grain legumes with a productivity of 2.83 t/ha of green pods and 418.4 kg/ha as grain legumes (area, production and productivity of livestock, Food and Agriculture Organization of United Nations, 2020). However, the area, production and productivity statistics of beans in FAO statistics may also include other beans such as mung bean and others (Sharma et al., 2013). French bean is also known by other names such as common bean, kidney bean, dwarf bean, haricot bean, string bean and garden bean. In India, French bean is also known by different names as Frash bean and Rajmah in Hindi, Shravanghevada in Marathi, Thingalaware in Kannada and Fras bean in Punjab.

Nearly 19.9% of India's GDP (Statistics Times.com, 2021) and 54.6% (According to the 2011 census of India) of the people are employed in agriculture, which is important for the country's economy. Despite making up the majority of landowners, small and marginal farmers confront a number of obstacles including restricted access to government services, contemporary technologies, and financial choices. In addition, they frequently experience crop failures and are heavily dependent on shady middlemen and local loan sharks. Following the Y.K. Alagh Committee's recommendations, the Indian government introduced the idea of Farmer Producer Organisation (FPO) in 2001. These organisations are designed to empower small-scale farmers by giving them the ability to communicate directly with consumers and strengthen their negotiating position.

Small-scale farmer groups known as FPOs band together to promote their shared products and pool resources. In India, there are already over 7,300 FPOs registered, with over 1.5 million farmers joining. The Indian government wants to bring together over a million farmers under the FPO umbrella by setting an ambitious objective of 10,000 new FPOs being established by 2024–25.

Intellectual property (IP) refers to creations of the human mind, such as inventions, literary and artistic works, symbols, names, images, and designs, which are protected by law. The protection of intellectual property is essential for promoting innovation, creativity, and economic growth. In order to ensure effective protection of intellectual property rights, various governing bodies, organizations, agreements, and treaties have been established at national and international levels. These bodies are responsible for setting and enforcing standards and regulations related to IP, as well as facilitating cooperation and coordination among different countries and stakeholders. Some of the major international organizations and agreements that deal with intellectual property include the World Intellectual Property Organization (WIPO), The Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS), and the Paris Convention for the Protection of Industrial Property. These organizations and agreements play a crucial role in creating a conducive environment for innovation, investment, and development, while at the same time ensuring fair and equitable access to intellectual property for all.

Introduction

Traditional Knowledge (TK) and Traditional Cultural Expressions (TCEs) are crucial intangible heritage passed down through generations in indigenous communities. TK encompasses indigenous knowledge, practices, and innovations related to cultural traditions, natural resources, and ecosystems, while TCEs are heritage artistic and literary expressions that embody traditional culture and knowledge. TK and TCEs are deeply embedded in the cultural heritage of indigenous communities, and play a vital role in preserving their identities, values, and beliefs. However, they are vulnerable to exploitation and misappropriation, which can lead to cultural loss and undermine the rights of indigenous peoples. Thus, it is crucial to involve indigenous communities in decision-making and protect their rights to safeguard and preserve the integrity of TK and TCEs.

Biotechnology has the potential to revolutionize many aspects in our lives, from healthcare to agriculture. However, along with its benefits, it also poses significant risks to human health, environment, and ecology. Therefore, it is essential to establish biosafety regulations and risk assessment frameworks to promote safe and responsible use of biotechnology. This chapter compiled an overview of biotechnology, the importance of biosafety regulations and risk assessment, IPR protection, contaminants, risk analysis, risk management in laboratories and fields, biosafety concerns to human health, environment and ecology, biosafety at international and national levels, bioethics, and general principles.

Overview of Biotechnology and its Potential Benefits and Risks

Biotechnology refers to the use of living organisms or their components to develop products and processes for various fields such as healthcare, agriculture, and environmental remediation. Biotechnology applications include genetic engineering, bioremediation, biopharmaceuticals, and biobased products.

Agriculture is the main stay of Indian economy as more than 70 per cent of the people of India are dependent upon this avocation and allied disciplines for their livelihood. Even today, at the dawn of 21st century, the Indian agriculture has continued to be the backbone of our national economy, representing country’s one third of Gross Domestic Product (GDP). Thus, farming families consisting of men, women, boys and girls known as the pillars of our agriculture, constitute backbone of the nation. The support and contributions made by the rural women in agriculture, constituting 55-66 percent of farm work force (Singh et al., 2012) are, however, not less than those performed by the men, and therefore they become spine of the rural economy. In fact, women’s role in the economy has been underestimated and their work in agriculture has long been invisible and unappreciated, if we compare the women’s work participation rate of some of the selected countries like Indonesia, Bangladesh, China. Pakistan and Sri Lanka, we find that India ranks second in position (22.7 %) after Indonesia (33.4%).

Introduction

The Indian literature viz; Vedas and other related books show that ancient Indians used to impart great significance to the gardens and parks. Indian rulers especially, the kings, the princess vis-a-vis affluent people took special interest in making vegetable gardens in the houses and fruit tree gardens in open areas. In those days, it was considered to be the foremost duty of a king to maintain the beautiful gardens in the city and around his palace. It is even said that only he should be revered as an ideal king whose abode is provided with spacious gardens having full of fruit bearing trees (Krishna murthy 2012). As a matter of fact, the gardens also contained pools and tanks adorned with beautiful lotus blossoms, having a number of plants and bushes laden with large number of fragrant flowers etc. Kautilya has included gardens and fields under the term of “Vastu”. So Vastu Sastra or the science of habitation may be taken to stand for laying out of gardens etc; including both horticulture and agriculture.

Horticulture involves the cultivation of fruits, vegetables, nuts, seeds, herbs, sprouts, mushrooms, algae, flowers, seaweeds, non-food crops such as grass and ornamental trees and plants. Various agricultural implements and tools are used in horticulture to facilitate the cultivation, care, and harvesting of these crops. Some common implements and tools used in horticulture:

Hand Tools

Pruning Shears/Secateurs: Used for cutting and shaping plants by removing unwanted branches or stems.

Hand Trowel: Small handheld tool used for digging, planting, and transplanting.

Pruning Saw: Used for cutting larger branches or stems.

A drainage system is a network of structures, channels, pipes, and natural features designed to manage and control the flow of water, primarily rainwater or surface runoff, away from inhabited areas, agricultural land, and infrastructure. The primary purpose of a drainage system is to prevent flooding, erosion, and water logging, thereby safeguarding public health and property, as well as ensuring the efficient use of land.

Surface Water Management: Surface water, which includes rainfall and other forms of precipitation, needs to be managed effectively to prevent damage to properties and the environment. Drainage systems collect this water and direct it away from vulnerable areas.

Catchments: A catchment or watershed is the area of land where rainwater collects and drains into a specific river, lake, or other water body. Understanding catchment areas is crucial in designing drainage systems because it helps determine how much water needs to be managed.

India is one of the most populous country in the world with a population of 1.26 billion (Census,2011). Of which women constitute about 49 percent of the population. Women act as a significant factor in development of the nation. Women from all sphere of life are contributing meaningly towards the prosperity of the nation. Especially, the rural farm women who constitute nearly half of the total rural population. The rural women are the mainstay of Indian agriculture. Their contribution towards agriculture development is worthy of praises. They are capable of accomplishing sustainable development in all the various activities which they have carried out and shown interest. Women are the essential part of society. For a society to develop, women should be given equal importance as the male counterpart. Nurturing of society is possible only if women are nurtured with equivalent opportunities and progress. Indian society is still male dominant, which accounts for low reputation of women. Women are treated as less competent human being. Through passing of time there have been acknowledgement by the Constitution of India on the part of importance of women as a productive humane resource for development of nation. Many measures have been adopted for the gender equality. This paved the way for advancement of empowerment of women.

Research being a continuous process for a scientific study, previous study provides basis for the research. The review of literature is necessary for developing conceptual frame work and suitable design for the study. It assists the researcher to keep his work going in right direction. The available literature related to the present study has been reviewed under the following heading:

2.1 Differential role accomplished by women dairy farmers from different social strata

Toppo et al. (2004) examined the participation of women farmers in dairy occupation in Anand district of Gujarat and their result revealed that 18.34 percent of the farm women were mostly engaged in activities related to artificial insemination, majority of the respondent (68.34%) participated in cleaning of the shed, while 25.00 percent of the farm women practised manure preparation and 95.00 percent of the respondent were not involved in preparation of gobar gas mixture.

Badole (2006) reported that majority of the responded had low socio-economic status.

The contribution of dairy sector in the Indian economy has tremendous impact on the country’s GDP. India being the world’s highest milk producing country, dairy industry has a major role in changing the twin problem of the nation that is poverty and unemployment. Dairy sector also involves the under privileged group, especially the dairy farm women. There are many success stories regarding the life changing experiences gained by the farm women, who had taken dairy farming as a means to sustain their livelihood. In the area of gender equality, dairy sector has proved to be a women centric enterprise. Most of the activities pertaining to dairy farming are mostly carried out by the farm women. The dairy farming activities carried out by the farm women are tedious and in major cases their contribution remains unnoticed. They are usually carrying out activities, where most of their energy is drained, resulting in drudgery. Matters related to decision making, their opinion about adopting new technologies, starting an enterprise are not given importance by their family members. This leads to a greater setback in the emergence of success of dairy sector. Therefore, empowerment of farm women in dairy sector is one of the important criteria for the dairy industry to reach a greater height and for overall development of nation.

Genomics is the study of whole genomes of organisms, it uses a combination of DNA sequencing methods, bioinformatics to sequence, assemble, analyse the structure and function of genomes. In another words, it can be defined as it is the study of the structure, function, and inheritance of the genome of an organism. Moreover, genomics focuses on interactions between loci and alleles within the genome and other interactions such as epistasis, pleiotropy and heterosis. Genomics is divided into two basic areas: structural genomics, characterizing the physical nature of whole genomes; and functional genomics, characterizing the transcriptome (the entire range of transcripts produced by a given organism) and the proteome (the entire array of encoded proteins).

Most biological traits are controlled by a large number of genes, which, in addition to their additive effects, may interact with each other, and their expression might be altered based on a variety of environmental effects. Researchers who were among the first to use molecular genetics to the study of cattle began by employing DNA markers to locate genes or sections of the genome affecting features of interest. For instance, identifying a group of genes based on Genome wide association study (GWAS) provides evidence that a causal relationship between a phenotype and a single nucleotide polymorphisms (SNPs) may exist. These findings of GWAS, however, do not improve our understanding of complex traits in which many pathways may be involved. The growing use of genotyping technologies has generated a large quantity of genomic information on the dairy population. Since the draft sequence of the bovine genome was published in 2009 (Zimin et al., 2009), whole-genome sequence data of cattle have also become available.

Introduction

The expanding number of people around the world necessitates an increase in the amount of food that is yielded. As stated by the Food and Agriculture Organization of the United Nations (FAO), global food production ought to be ramped up by a factor of two in the next few years in to meet the requirements of the growing global population in terms of consumption (FAO, 2006). This is because the global population is expected to continue growing at a rate of approximately one person every two seconds until the year 2050. It is possible that the predicted production disparity could be filled by making improvements in genetics, animal health, and the excellence of animal husbandry.

The production of animals has expanded significantly over the course of the last several decades as a direct result of the application of quantitative genetics in animal breeding. However, due to technological limitations, the use of genetic markers in breeding programmes has only been implemented to a relatively small extent (Deng et al., 2016). The concept of genomic prediction, which was first introduced approximately twenty years ago, has completely transformed the planning and execution of animal breeding operations.

Introduction

The key factor of sustainability in the animal sector depends upon genetic improvement in domestic livestock. There are many reproductive and molecular biotechnologies used for the genetic improvement of domestic livestock and they are synergistically coupled with the breeding program in distinct breeding targets. With the help of gene editing techniques (e.g. CRISPR etc.). To improve the specific traits of interest scientists can add, delete or replace the nucleotides (e.g. milk production, meat production, disease resistance, etc.) in less than one generation. Gene editing with the conventional breeding program in livestock is an important factor for genetic improvement for increasing the rate of genetic gain. In the present topic, here, we delved into the most important reproductive and molecular technologies used in livestock genetic improvement, as well as the most effective ways for incorporating gene editing into existing genetic improvement programmes and targeting specific traits for enhancement. The improvement in genetic level is a most powerful part of sustainable animal development because it is permanent and the effects are long-lasting and cumulative. Genetic advancements produced in one generation are passed on to the following, unlike dietary and animal health treatments, which are a continuous process. The many livestock operations that involve chemical and mechanical methods such as dehorning requires time, worker, money, animal safety, etc., but their genetic alternation of the concerned gene for the polled or hornless condition can exclude the requirement of physical dehorning. (Gottardo et al. 2011; Tompson et al. 2017).

Introduction

Wool which obtained primarily from sheep is an essential textile fiber that is used across the world. Whether for clothing, canvas work, carpets, or even upholstery, wool is a vital resource supporting many industries and occupations. This natural fiber has many benefits, such as being biodegradable, easy to clean and even having a natural structure that traps air which is excellent for heat retention. The annual wool production is 2 million tones. China ranks first in terms of global wool production. With a production of more than 333,624 tonnes of wool in 2020, China accounts for approximately 19% of the global wool clip. Australia produces 16% of global wool and is by far the largest wool exporter in the world. There has been a constant increase in the demand of wool products worldwide. This has made scientists to try to improve livestock and livestock associated derivatives. The conventional system along with the recent biotechnological interventions will be helpful for enhancing wool quality and production.

Origin of Insects

Insects are highly specialized group of invertebrates belonging to the largest animal Phyla, the ARTHROPODA, which also includes in it, the prawns, crabs, lobsters, centipedes, millipedes, scorpions, ticks, mites and spiders. Practically three fourth of the animal species come under this phylum.

The Arthropods evolved during Cambrian period from primitive annelidan ancestor. The main evolutionary stem of Arthropod is represented by the Crustacia- Insecta- Myriapoda.

The insects originated in the Devonian period of Palaeozoic era. Diplura and Thysanura are the most primitive wingless insects while mayflies, damselflies, dragonflies and stoneflies represent the primitive winged insects.

Evolution

Evolution is a process whereby population are altered over a period of time and may split into separate branches, hybridize together or terminate by extinction.

Man has tendency to classify everything in a hierarchical manner for example, ships may be classified on size, weight, what they carry or naval versus merchant or passenger. Any of these classification is as valid as any other.

But classification of biological species is unusual in that a predefined system exists i.e. the evolutionary relationships among organisms. But evolutionary relationships can only be estimated; and contrary to popular belief, even a good fossil record does not conclusively show the phylogeny or evolutionary tree of a group species.

Numerical taxonomy can be defined as “Numerical evaluation of the affinity or similarity between taxonomic units and ordering of these units into taxa on the basis of their affinities”. The term includes drawing of phylogenetic inferences from the data by statistical or other mathematical methods to the extent to which this should prove possible. The practice involves a number of fundamental assumptions and philosophical attitudes toward taxonomic work.

The Species Concept in Systematics

The modern biological or, more strictly, genetical concept of a species is a group of interbreeding organisms, genetically isolated from other such groups. The definition of the category species has long been one of the major problems of taxonomy. It is because of two reasons:

1. Because of the congruity of lingering typological concepts with the nature of evolving species.

2. Because evolutionary species may have changing characters and are only gradually differentiated in phylogeny.

For evolutionary study and descriptive purposes, many kinds of variation within species come in to consideration, but the only regular intra specific taxon is the subspecies. Subspecies are widely but not universally useful and their definitions yield to the same sort of criteria as for dividing other phylogentic continuance.

Identification of the insects is the integral part of systematics. It utilises all taxonomic procedures. The collections in the world are the accumulation of past taxonomists and are stored for the future identifications. Every species name is based on a published description or figure and usually on the type specimen. Identification is the association of other specimens with the appropriate description or with type specimen.

The steps in identification are as follows:

1. Preliminary key to orders and families

2. Key to genera and species if recent monographs or faunal works are available

3. Reference to the most recent catalogues

4. Reference to current bibliographies for literature published subsequent to the most recent catalogues

5. Reference to original descriptions

6. Comparison with the authentic described specimens or with types.

Introduction

Virtual supply chain management is the digital representation of inventory data that the managers manage from anywhere in the world. In the 1980s, when the proliferation of computers gave more importance to the human resource, f inance, and manufacturing units communicating with each other for better quality work, that led to enterprise resource planning, and slowly each task of supply chain management started virtualizing in its full length.

A virtual supply chain has advantages such as better inventory control, shorter lead times, quicker order fulfilment, increased supply chain visibility, more accurate demand forecasts, and higher customer satisfaction. It gives businesses the ability to make the most use of their resources, cut expenses and lessen waste throughout the supply chain.

However, putting in place a virtual supply chain calls for thorough planning technology integration, and network-wide process alignment. Overcoming obstacles like data security, interoperability, and change management are all part of it. To fully reap the rewards of a virtual supply chain, businesses must also invest in technical infrastructure, training courses, and partnerships.

14.1 NEED FOR ANIMAL DISEASE INFORMATION SYSTEMS

Once the animal disease data are gathered, a few things need to be done with the data so collected. First, they must be managed and quality checked; Secondly, they must be analyzed to be understandable; and thirdly, they must be acted upon. For data to be analyzable and useful for decision-making, they need cautious management and quality control. An information system is the collection of data, people, procedures, hardware, software, files, and data required to accomplish an organized set of functions.

The constituents of an information system are:

• People – those who gather data, those responsible for data input and those responsible for data analysis

• A storage / retrieval / analysis system – which consists of computer hardware and appropriate software

• A feedback delivery system – mechanisms to ensure that processed data are fed back to data gatherers

Opportunities

India is home to largest milch animal population, totalling around 100 million cattle and buffalo (out of total population of 300 million) spread over 6.5 million census villages. India is the largest milk producer with CAGR of 4.5%, likely to go up to 5%, which is likely to create around 20 million jobs every year. The most significant factor is that dairy industry is likely to exceed IT industry in employment generation. In year 2018, India produced 146 million tonnes of milk contributing 26% of the agriculture GDP.

But the foundation of dairy industry is economically vulnerable as per animal productivity and fertility are very low leading to meagre profits and frequent demands to enhance procurement price. National schemes like Operation Flood, National Dairy Plan-I and National Dairy Plan II, largely focussed on milk collection, processing, distribution and organising farmers but the animal component has been neglected. Enhancing per animal productivity by empowering farmers to scientific management and breeding to achieve genetic improvement needs urgent attention. Although numerous technologies to improve health and genetics are available but the single most important gap is failure to deliver these to farmers. Unlike western world, India has not been able to develop modern veterinary service delivery models. In order to cater to breeding and health services of cattle and buffalo (300 million in numbers) and also pet animals in rural areas and small towns, huge manpower and infrastructure will be required.

Being polytocous animal, sow give birth several (8-14) piglets in each farrowing, mother pig find several deficiencies and disorders during gestation, farrowing and postnatal conditions. Prior to birth intrauterine competition amongst the feotus piglets for nutrition and gas exchange is a big stress for abortion. Several infectious and non-infectious causes may hamper proper growth and pathological conditions resulting mortality (15-20%) in piglets than weaner and adults (Sarma, et al, 2012). Several risk factors are also responsible for piglet mortality.

Prenatal factors: Insults during pregnancy can impact a piglet’s ability to survive after birth and regulate their body temperature. Some maternal aspects that affect survability and mortality amongst piglets are prolong farrowing duration more than 4 hours, number of parity of sow, usually first and second parity show high mortality than subsequent parities and also older sow lose more piglets.

Introduction

Climate change, a global phenomenon of present time, has emerged as the greatest challenge of the world in the twenty-first century. Rising earth’s surface temperature is one of the most threatening factors coming into view. The substantial changes in the earth’s climate have an impact on ecosystems, economics and societies in a variety of ways (Sharma et al., 2024). It is one of the important environmental, agricultural, human and animal health issue. Climate change is an association of multidimensional effects involving physical characteristics, causes and consequences (Visschers, 2018). The climate change has resulted in to increasing global average temperature of air and ocean, melting of snow, rising of ocean level, change in the rainfall pattern and extreme whether events such as drought, flood, heat waves, storms etc.

Doppler echocardiography relies on detection of the shift in frequency of ultrasound signals reflected from moving objects. With this principle, conventional Doppler techniques assess the velocity of blood flow by measuring high-frequency, low amplitude signals from small, fast-moving blood cells. In TDI, the same Doppler principles are used to quantify the higher-amplitude, lower-velocity signals of myocardial tissue motion.

There are important limitations to TD interrogation. As with all Doppler techniques, TDI measures only the vector of motion that is parallel to the direction of the ultrasound beam. In addition, TDI measures absolute tissue velocity and is unable to discriminate passive motion (related to translation or tethering) from active motion (fiber shortening or lengthening). The emerging technology of Doppler strain imaging provides a means to differentiate true contractility from passive myocardial motion by looking at relative changes in tissue velocity.

Precision medicine and personalised treatment of systemic or tumour diseases gain their acceptance and application in veterinary care, too. The application of personalised medical protocols and companion diagnostics is easier and ethically well reasoned within the veterinary medical field – and it can offer many advantageous lessons to human clinical transformation, too [1]. In vitro companion diagnostics for testing the applicability and sensitivity levels of certain kinase inhibitor and immunotherapeutic drugs offer a greatly increased efficiency for veterinary cancer patients, too. As the understanding of cancer biology has advanced, the field of veterinary oncology has grown significantly, paralleling developments in human oncology. Precision medicine is an innovative approach to disease treatment and prevention that considers individual variability in genes, environment, and lifestyle. In the context of veterinary medicine, precision medicine aims to provide tailored therapies that are specifically designed for the unique genetic and molecular profile of each animal’s cancer. This approach moves away from the traditional “one-size-fits-all” model, instead focusing on targeted treatments that maximize efficacy while minimizing side effects. Companion diagnostics, such as molecular tests, help determine whether a dog or cat is likely to respond to a particular drug. For dogs and cats, precision medicine holds great promise in improving outcomes for cancers, which are among the leading causes of death in companion animals.

As the heart diseases in companion animals is becoming common as in humans, the research in canine cardiac diseases is one of the most extensive studies in the present scenario. As per the available literature, the overall occurrence of various cardiac abnormalities ranges from 0.37 percent to 1.67 percent in various parts of the country. Whereas, in western parts of the globe, nearly 8 million dogs suffer from heart disease accounting 10% of all dogs in the United States. Heart diseases are common among older dogs; up to 75% of senior dogs have some type of heart condition, and unfortunately, most go undiagnosed due to varied reasons. The recognition of canine cardiac diseases has been delayed, and ignored on account of lack of awareness and knowledge by the owner and inadequate diagnostic facility in our country. Physical examination, radiography, electrocardiography and echocardiography are most useful diagnostic procedures employed in diagnosing the cardiac diseases in dogs. However, majority of the acquired cardiac diseases are being managed medically with one or a combination of drugs. Improved diet management and health care of companion animals have led to increased life expectancy, as a result, cardiac diseases have become pivotal causes of death for both dogs and cats. For such reason, a major objective has become to increase the quality of life by reducing the expansion of cardiac diseases via early detection of diseases and provision of effective treatment.

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).

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.

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.

10.1. Introduction

Decision-making is a fundamental aspect of human life, influencing choices in both personal and professional settings. Every individual, whether consciously or unconsciously, engages in decision-making daily, ranging from simple tasks like selecting a meal to complex strategic planning in organizations. However, decision-making becomes increasingly challenging when multiple conflicting criteria are involved. The presence of numerous factors, each with varying degrees of importance, often creates ambiguity and uncertainty, making it difficult to arrive at the most suitable option. To address these challenges, structured decision-making methodologies have been developed to provide a systematic and logical framework for evaluating alternatives.

One such widely recognized method is the Analytical Hierarchy Process (AHP), introduced by Thomas L. Saaty in the 1970s. AHP was designed to assist decision-makers in breaking down complex problems into a structured and systematic hierarchy. This approach allows for a step-by-step evaluation of different factors, making it easier to analyze their relative importance. By structuring a problem into different levels - such as goal, criteria, sub-criteria, and alternatives - AHP provides clarity in decision-making and enhances consistency in judgments. The method is particularly beneficial when dealing with decisions that involve both tangible and intangible factors, as it allows subjective preferences to be quantified systematically (Saaty, 2008).

15.1. Introduction

Meta-analysis is a statistical technique used to combine the results of multiple studies to produce a single, more precise estimate of the effect size of a particular intervention or association. It is a powerful tool in research, particularly in f ields such as medicine, psychology, education, and social sciences, where it is often necessary to synthesize evidence from numerous studies to draw meaningful conclusions. This chapter provides a comprehensive overview of meta-analysis, including its history, methodology, advantages, limitations, and applications.

15.2. Historical Background

The concept of meta-analysis dates back to the early 20th century, but it was not until the 1970s that the term was coined by Gene V. Glass. Glass defined meta-analysis as “the statistical analysis of a large collection of analysis results from individual studies for the purpose of integrating the findings” (Glass, 1976). Since then, meta-analysis has evolved significantly, with advancements in statistical methods and software making it more accessible and robust.

15.3. The Need for Meta-Analysis

15.3.1. Accumulation of Evidence

In many fields, particularly in medicine and psychology, a large number of studies are conducted on the same or similar research questions. However, individual studies may have small sample sizes, leading to low statistical power and inconclusive results. Meta-analysis allows researchers to pool data from multiple studies, increasing the overall sample size and statistical power, thereby providing a more reliable estimate of the effect size.

Concept of Delinting

Cotton seed clumps because of linters getting trapped on them after ginning. Gin-run seeds have very low flowability and do not singulate, making cleaning, upgrading, and precise metering in planting operations challenging or impossible. To singulate the seed and increase flowability, a variety of techniques have been and are employed. Most of the techniques entail removing the tags and linters entirely or partially, although other coating techniques have also been attempted with mixed results, both financially and technically (Mezynski, 1966; Webber and Boykin, 1907).

Methods of Delinting

1. Mechanical Delinting

Mechanical delinting is the usual technique used to improve the flowability of cotton seed. As previously indicated, mechanical delinting basically involves resharpening with finer, closer-spaced saws to remove part of the commercially valuable linters.

Stored grain pests are one of the major constraints in obtaining quality seeds. They cause substantial yield loss in storage conditions affecting both the quality and quantity of the produce. Apart from causing direct loss to the grains, they also make them unfit for consumption through their excreta, scales and wings resulting in development of unpleasant odour (Upadhyay and Ahmad, 2011). They also act as a source of medium for growth of fungi or bacteria (Daglish et al., 2018). The method of infestation of stored gain pests is different from the insect pests infesting crops under field condition. Generally, the infestation of storage pests starts after harvesting. It has been reported that in India, there is a loss of about 14 million tons worth Rs. 7000 crores due to the infestation by different storage pests (Chaubey, 2022). The post-harvest loss in terms of quantity and quality by different storage insect-pests accounts for about 10-30 per cent (Rajasri and Kavitha, 2015; Yaseen et al., 2019).
