It appears that cattle were domesticated prior to 4000b)c)From 1961 to 2021, the amount of milk produced worldwide has almost tripled, reaching 918 million tonnes. Production of milk is carried out by about 150 million households worldwide. Smallholders produce the majority of the milk in developing nations, and milk production supports nutrition, food security, and household livelihoods. For small-scale farmers, milk offers comparatively quick returns and is a significant source of revenue. Small-scale farmers using native or local cattle breeds produce the majority of the milk in developing nations; however, to meet the growing demand for milk and milk products in peri-urban areas, more improved or cross-bred cattle are being used) India is an agricultural country that contributes significantly to the economy. Animal husbandry is an adjunct to agriculture and has vital livestock resources, with cattle and buffalo playing an important role in improving the socio-economic status through contributions to milk, meat, hides, and draft power for agricultural operations. India is one of the world’s top milk producers contributing 24 percent of global milk production and having a large number of indigenous

The term “Economics” is derived from the Greek words ‘OIKOS’ and ‘NOMAS’ or ‘NEMEIN’. ‘Oikos’ means house hold and ‘Nomas’ or ‘Nemein’ means management. So, in its original sense-economics means house hold management; i.e. satisfying as many wants of the house hold or family as possible by allocating the limited resources at the disposal of the family wisely among different wants. In the modern and practical sense Economics means management of day-to-day problems arising from unlimited wants and limited resources by wisely allocating limited resources to satisfy maximum wants. Divisions or approach of Economics There are two approaches a) Traditional approach and Modern approach. Traditional approach is divided into six main divisions, viz., (i) Production, (ii) Distribution, (iii) Exchange, (iv) Consumption, (v) public finance and (vi) economic planning. Modern approach studied under (i) Income Theory or Macro Economics; and (ii) Price Theory or Micro Economics, deals with the study

Livestock plays a vital role in any country’s economy as animals are a source of livelihood for people, providing milk, meat, and fur, and are used for agricultural work. Hence, the loss of animals due to disease or any other reason results in loss of wealth, livelihood, and nutrition. In view of this, management of mortality on farms is of utmost importance. There are different ways to manage and dispose of dead animals. The acceptable methods to manage mortality include composting, rendering, incineration, landfills, burial, and disposal pits. Composting is one of the options for managing mortality on farms. Composting is the decomposing of carcasses by natural processes, viz the use of bacteria, fungi, and other microorganisms to convert organic matter into a stable product called compost. Composting involves the degradation of the carcass by anaerobic bacteria to convert it into liquid material with odor and gases such as hydrogen sulfide and ammonia)The anaerobic process produces heat that kills many viruses and bacteria and allows the growth of only heat-tolerant bacteria)The temperature continues to rise and peaks between 130 to 160 0F. Composting requires a source of energy

Food is defined as any substance, whether processed, semi processed or raw, that is intended for human consumption as well as the inedible parts associated with food that are not intended to be consumed by humans. Food waste is defined as any food and inedible parts of food, removed from the food supply chain that can be recovered or disposed, whereas, food loss is defined as food that unintentionally undergoes deterioration in quality or quantity as a result of food spills, spoils, bruising, wilting or other damages alike owing to infrastructure limitations at the production, storage, processing and distribution stages of food lifecycle. Global food waste management is an issue of concern that requires attention from various stakeholders having diverse expertise. According to statistics, about one third of the food produced for human consumption is either lost or wasted. Globally, the cost of food waste accounts for USD 2.6 trillion, of that USD 1trillion is incurred from greenhouse gas (GHG) emissions, water scarcity, biodiversity loss, increased conflicts and loss of livelihood owing to issues like soil erosion, nutrient loss, reduced yields, wind erosion and pesticide exposure.

Manure can be a) solid manure, feed waste, soiled bedding, etc. and b) liquid – urine and detergent Water. Ideally, solid manure is usually collected and removed twice daily. India has about 535.78 million livestock and the amount of production of animal waste amounts to about 3 million tons per year. Together farm-level livestock waste includes manure, urine, placenta, bedding,Feed waste, milk house waste etc. These animal wastes are the biggest source of harmful gases, harmful pathogens and odors and therefore public health and environmental concerns. Livestock waste contains many useful substances components that, if recycled effectively, can be used as fertilizer for crops, food for animals. Economic savings are the biggest benefit of waste management achieved through improvements in human health and the environment, leading to higher productivity, lower medical costs, etc ultimate increase in farmers’ income. The animal waste is a major source of harmful gases, harmful pathogens, etc Odor;

Livestock transportation is a process of carrying animal from one place to another by different means of transportation. It is a stressful, threating and not familiar event of domestic animals. Livestock is transported for many reasons like marketing, slaughter, changing of owner, re-stocking and desirable grazing area)Animals who are transported for slaughter are stressful due to various component like loading, unloading, restraining, unfavorable weather condition, thrist, hunger. During transportation there are many rules and regulation by different countries which should be strictly implemented) Cattle and other animal species should be transported with partition. Birds and lab animals are transported in cages or any airy cartridge or basket. During transportation food and water should be withheld for 24 hours. if the transportation is more than 24 hours animal should be watered and fed in transit.

Introduction Colostrum feeding • Colostrum is rich source of gamma globulins (antibodies), vitamins and minerals • Colostrum Temp.: 99ºF-102ºF • Colostrum feeding: first 3-5 days. • Whole milk: after 5 days • Feed the total amount of milk at 3 or 4 equal intervals up to the age of 7 days and then twice daily • Quantity of colostrum: 10 % of body weight. • Overfeeding: calf scour/diarrhea. • Around 0.5% of a cow’s yearly milk production is made up of colostrum. • After birth, the amount of immunoglobulins that can be absorbed from colostrum drops by 1/3 as soon as 6 hours, by 2/3 after 12 hours, and an intestinal barrier forms after 24 hours. • Colostrum must be given in sufficient amounts to the newborn calf because during the first 24 hours after parturition, the permeability of the stomach and the concentration of immunoglobulins drop sharply. • Cow colostrum must meet minimum requirements for both immunological and bacteriological characteristics:

Raising healthy and productive animals is a cornerstone of successful livestock farming. Whether the goal is milk production, meat, draught power or breeding, the foundation of a thriving animal enterprise lies in appropriate general management and feeding practices that consider the animal’s stage of growth, reproductive status and work requirements. Each class of animal—calves, heifers, pregnant and lactating females, dry animals, bulls and working animals—has unique physiological needs that must be addressed through specialized care and nutrition. Modern animal husbandry aims not just at higher productivity but also at ensuring animal welfare, sustainability and profitability. Scientific and stage-specific practices improve the animals' lifetime performance and reduce mortality, disease incidence and reproductive failure. In this context, proper rearing practices are not merely a routine, but a strategic necessity. The calf represents the future of the herd. Ensuring its survival, growth and development is crucial for long-term productivity

Introduction Care and management of calf • Begins before its birth. • Good dairy herds are raised rather than purchased. • Dam should be dried 6-8 weeks before expected calving and should be fed well. • Underfed dam will give weak and small calves. Steps of calf management 1.  Removal of mucous • Immediately after birth:  removal of mucous or phlegm from nostril, mouth, eyes & ears for normal breathing. • Rub and dry the calf with a dry cloth or gunny bag • If cow not licking: sprinkle a little common salt on calf’s body. • If calf does not start breathing: Provide artificial respiration by: • Compressing and relaxing the chest with hands • Swinging • Inserting twig in nostril 2.  Ligation of naval cord • Cutting of naval cord: ligate-2.5cm & cutting-1cm below.

The Convention on Biotechnology has defined biotechnology as “any technological application that uses biological systems, living organisms or derivatives thereof, to make or modify products or process for specific use”. The global food requirement is increasing with growing population, so the productivity gap could be filled by improving genetic health. Animal breeding focuses on genetic improvement through biotechnological and genomic approaches. Genetic progress is influenced by the type of biotechnology such as selection accuracy, genetic interval, intensity of selection, genetic variance. It helps to improve animal production, treatment of genetic disorders, production of transgenic animals resistant to diseases, vaccine production and also to maintain genetic diversity for endangered species. Genomic selection is a type of marker assisted selection. It improves the genetic gain by decreasing genetic interval and improving reliability. These novel approaches have high potential in animal breeding, if executed judiciously may provide practical benefits to mankind. The magnitude of genetic improvement of livestock species

The study of general reproduction and reproductive performance in animals is a vast and intricate field that spans across various species, habitats, and biological systems. Reproduction is a fundamental biological process that ensures the continuity of life across generations. It involves a series of complex physiological and behavioural events, from mating and fertilization to gestation and birth. The general reproduction and reproductive performance in domesticated animals is a fascinating and complex field that has significant implications for various aspects of human society, including agriculture, pet ownership, and conservation efforts. Domesticated animals encompass a wide range of species, from farm animals such as cows and chickens to pets like dogs and cats, and even animals kept for conservation or recreational purposes, such as horses and certain bird species. Each of these species has unique reproductive systems and cycles, and understanding these is crucial for effective management and care. For instance, the gestation period for dogs is typically around two months, while for horses, it’s closer to a year. Similarly, some birds, like parrots, may lay eggs only once or twice a year

Current status of feed and fodder availability in India Globally India ranks 1st in terms of total livestock (535.78 million) and buffalo population in the world (109.85 million), 2nd in cattle (192.49 million), goat (148.88 million) and 3rd in sheep population. So, the availability of adequate quantity and quality feed and fodder resources for livestock is essential for improving livestock productivity. Grazing lands and fodder cultivation areas are gradually dwindling either due to degradation or restriction for livestock grazing. Total area under fodder cultivation is around 8.4 mha (5.23%) which is almost static for the past two decades. Even though feed and fodder availability has improved in the last decade still gap exists with demand and availability of fodder during lean periods and abnormal weather conditions like droughts/floods. At present, India faces a net deficit of 35.6% green fodder (GF), 10.95% dry crop residues and 44% concentrate feeds. In India, open forest cover is around 29 million hectares (mha), which can be further utilized for growing fodder trees without affecting standing trees, mostly as an under- storey on the partially shaded ground Area under fodder production Sorghum (2.6 M ha) and Egyptian clover (1.9 M ha) account for roughly 54% of the total cultivated fodder area in the kharif and

Selection is a phenomenon of giving preference to certain individuals in a population to reproduce over other individuals that are deprived of the opportunity to reproduce. In common parlance, it is the process to choose individuals from the herd that are going to produce the next generation and influence the performance of the herd. Performance of a herd is guided by the genes of the parents. In a herd, males give rise to more off springs and hence selection of males is an opportunity to boost cattle husbandry. The contribution of males to the inheritance of polygenic traits is equal with that of females. Hence, it is central to pay equal emphasis while selecting males and females. Selection of sire is more important than dam selection due to numerous reasons. The first reason is that a sire produces more numbers of progenies compared to one dam. Since a sire is called “half the herd”, it determines the performance of the herd. Modern initiatives like artificial insemination and frozen semen technology has further extended the use of sire and highlights the importance of sire selection. Artificial insemination has allowed the superior traits to reach different corners of the globe and this has benefitted the present generation at large. Frozen semen technology together with artificial insemination is milestone to the field of genetics and breeding. It is now possible to

Animal flesh when consumed as food is known as meat. Meat was introduced into man’s diet early on during Stone Age when they were hunter and gatherer. Humans seem evolved to a meat diet based on the structure of teeth and the unsophisticated nature of our digestive system. Presently man used many varieties of animals’ species for producing meat however domesticated cattle, goat, sheep, buffalo, pig and poultry continue to be major contributor of meat to the ever increasing human population. Meat is one of the best and major sources of protein for human, meat protein content all the essential amino acid in required quantity and is easily assimilated by human guts. Fat is essential for development of flavor; at least the bare minimum is desire. Besides this it also has all the other crucial nutrients in smaller amount.  The essential elements of good quality meat are firm texture, moderate fat content, tender, good flavour, juiciness and normal meat odor, and to produce such meat it require proper care and management of meat animal. Hence, right and efficient management is to be given to the animals for producing better meat quality. Management broadly includes selection of genetically superior animals,

Genetic characterization using DNA markers is a cutting edge technology that makes it possible to study animal variability at basic level. A genetic marker can be any stable and inherited variation which is measurable or detectable by a suitable method and can be used subsequently to detect the presence of a specific genotype or phenotype other than itself, which otherwise is non-measurable of very difficult to detect. Such variations exist at morphology, chromosome, biochemistry or DNA levels that can serve as genetic markers. Molecular markers are the markers that reveal variations at the DNA sequence level. The polymorphisms observed at the DNA sequence has many applications which include percentage determination, genetic distance estimation and evolution, determination of individual identity, identification of disease carrier (heterozygous) animals, determination of twin zygosity and freemartinism, gene mapping, marker assisted selection (MAS), sex determination, DNA fingerprinting and transgenic breeding. Gene mapping is a tool to identify the genes responsible for specific traits.  The genetic map is constructed from linkage relationship based on the frequency of meiotic exchange (amount of recombination) among linked traits. Genetic map helps

Livestock sector is an important subsector of the agriculture of Indian economy. It forms an important livelihood activity for most of the farmers, supporting agriculture in the form of critical inputs, contributing to the household, supplementing incomes, offering employment opportunities, and finally it acts as a supplementary and complementary enterprise. Livestock plays a vital role in the economic development of the country. Livestock Sector has continuously been growing and contributed 4.90% (at constant prices) of total GVA (Gross Value Added) in 2020-21 (Annual Report, 2021-2022). India ranks first among the world’s milk producing nations, achieving an annual production of 230.58 million tonnes of milk and with per capita availability of 459 gms/day during the year 2022-23 (Annual Report, 2022-2023). In India, livestock population includes cattle (193.46 million), buffalo (109.85 million), sheep (74.26 million) and goat (148.88 million) (20 th Livestock Census, 2019). The rapidly expanding demand for livestock products offers an opportunity as well as a challenge to livestock production. The livestock sector is moving towards specialization with the increasing involvement

The agro-food & slaughter house animal by-product industry generates large amounts of waste that contribute to environmental contamination and leads to pollution. Animal byproduct production, as part of the meat and poultry processing chain, is huge. Animal fat waste constitutes some of the most relevant waste and the treatment of such waste is quite costly because environmental regulations are quite strict. Fossil fuels remain the main source of primary energy accounting for over 80 % of worldwide energy consumption. The continuous consumption of non-renewable resources is leading to their fast depletion while causing the accumulation of CO2 and other greenhouse gases (GHGs) in the atmosphere. Also, energy demands are expected to rise by over 25 % by 2040, which claims for a shift toward the use of renewable and carbon-neutral fuels to ensure environmental and economic sustainability. About millions animals (cattle, sheep, pigs and goats) and poultry (mainly chickens and turkeys) were slaughtered various parts of countries. Such a high number of slaughtered animals produces enormous amounts of waste animal residue including fats that need to be treated to reduce pollution or recycled to

Animals worldwide provide meat, milk, eggs, draft power, skins, transportation, and a variety of other useful items. India has a vast livestock population with a diverse spectrum of species. Animal husbandry plays an important role in the life of rural farmers. Animal breeding is an area of science concerned with sound animal husbandry methods. Animal breeding is the use of genetics and reproductive physiology to improve the genetic makeup of animals. The goal of animal breeding is to improve not only individual animals, but the entire animal population. The breeder has two basic tools namely selection and breeding for genetic improvement of livestock. The kinds of selection are natural and artificial selection. In artificial selection, breeder has choice to choose superior animals over the average of population for desired traits and allow them to produce offspring for future generation. Animals are selected using four criteria (basis): individual selection, pedigree selection, family selection, and progeny testing selection. Individual selection selects animals based on their own performances.  Individuals are chosen through pedigree selection using ancestral records. In Family selection,

Animal and poultry feed and fodder production management is a vital aspect of the agricultural industry, playing a pivotal role in sustaining livestock health and productivity. This intricate domain encompasses a myriad of practices, technologies, and strategies aimed at producing high-quality feed and fodder to meet the nutritional needs of various animal species, ensuring their optimal growth, development, and overall well-being. Feed and fodder production management involves the cultivation, processing, and formulation of feed ingredients tailored to the specific dietary requirements of different animals. From traditional practices to modern, technology-driven methodologies, this field has evolved significantly to address the growing demands of an expanding livestock industry. The cornerstone of effective feed and fodder management

A system of housing is more are less synonymous to the system of management of livestock. Housing is essential to protect the animals from adverse climatic condition (rains, hot and chilly winds). Housing also help to maintain normal health of animals by proper feeding watering and reducing environmental stresses.  Housing allows the animals for proper rest, moderate exercise, suitable micro-environment and proper ventilation which are essential for comfort of the animals. While selecting the site a site for establishment of a dairy farm some points should be considered regarding topography, soil, nearby market, availability of labour, electricity, water etc. The housing system can be divided in to two type viz. conventional housing and loose housing system. The conventional housing system may be single row or double row depending upon the number of animals. The dairy farm consists of various building for different classes of livestock like calf shed/ lamb/kid/piglet pens, milking barn, maternity pen, cow shed, heifer shed, shearing room, slaughter house of pig etc. The ancillary structure of  a farm  are stores for keeping feed materials, equipment, milk house, silo, generator room, pump houses, AI centers, workers retiring room, office etc. The floor should be impervious and non-slippery. The floor should have a gradient toward the drain of 1 in 40 in covered area and 1in 60 in the open area for easy drainage of urine and washing of animals. The roof should be light, strong

Livestock plays a pivotal role in sustaining the livelihood of millions of people worldwide, particularly in rural and semi-urban communities. Beyond providing food products such as milk, meat and eggs, livestock also contribute to income generation, draught power, manure for agriculture and socio-cultural functions in many regions. The health and productive performance of livestock animals are central to achieving the economic, nutritional and ecological goals of animal husbandry. Any compromise in animal health or productivity directly impacts farmers’ income, food security, and national agricultural output. Animal health is the foundation of productive and sustainable livestock farming. Good health ensures animals can grow, reproduce and perform at their genetic potential. Conversely, disease, poor nutrition and environmental stress can severely reduce productivity and increase mortality. Common health challenges in livestock include infectious diseases (bacterial, viral, and parasitic), metabolic disorders and management- related stress conditions. Moreover, zoonotic diseases—those transmissible to humans— are of growing concern in the context of public health and food

Animals are exhibited in various ways and events like in fairs, judging shows, in circuses, in zoos and as performing animals. Some famous animal fairs in northern part of the country are Sonepur cattle fair of Bihar. It is the largest cattle fair of Asia, held on the confluence of holy river Ganges and Gandak annually on KartikPoornima in the month of November for the trade of animals such as Cattle, horses,goats,donkeys,camels,birds and elephants. Haathi Bazaar is the major attraction of SonepurMela. Nagaur cattle fair held during the months of January and February. It is the second biggest cattle fair in India. Pushkar Cattle Fair,popularly known as camel fair held for five-days between the months of October and November. Cattle shows are organized time to time where animals are judged for their different characteristics, selecting for their best type, possessing true breed characteristics, dairy conformation, good temperament, proper growth and development according to its age, with optimum condition of fleshing and free from defects. To take part in such shows animals are transported to different places. So, apart from knowledge of restraining methods, concept related to ageing, animal handling (flight zone, point of balance) animal behavioural consideration and welfare indicators are of much importance for transporting and presenting animals in any show. Some of

Introduction Livestock is a global resource with significant benefits to society in the form of food, income, nutrients, employment, insurance, traction, clothing and others. Livestock sector of India holds among one of the largest globally. Around 20.5 million people depend on it on livestock for their livelihood. Livestock farming contributed 16% of small farm income households compared to an average of 14% for all rural households. provides livestock Livelihood for two thirds of the rural population. Furthermore, it provides employment to around 8.8% of the workforce population in India. India has huge livestock populations. The livestock sector contributes 4.11% GDP and 25.6% of total agricultural GDP. Livestock count Livestock farming plays an important role in the farmers’ economy. The farmers in India Maintaining a mixed farming system, i.e

Poultry manure provides an ideal habitat for fly breeding due to high manure moisture leading to increased fly populationand fly menace in poultry farm. The moisture, temperature and humid condition play important role in fly breeding. The flies on poultry farms are unacceptable as they act as a reservoir of many diseases and spread diseases to birds and human beings. In addition to spread of diseases, fly are nuisance to birds as they distract the birds as well as poultry farm employees, nearby farms and residence (Berry, 2003). High fly population contribute tapeworm infestation in flock and disseminate bacterial (like salmonella, fowl cholera, etc.) and viral diseases (Bird flu, New Castle disease, etc. in flocks. Fly population also causes public health issue leading to pressure on poultry farmers to control fly population on poultry farms to acceptable level. The flies on poultry farm includes House fly (Muscadomestica), little house fly (Fanniacanicularis), Black Garbage fly (Hydrotaeaaenescens), Dump flies (H? aenescens, H? ignava, H? capensis), Drosophila flies (Drosophila repleta), Soldier fly (Hermetiaillucens), Stable flies (Stomoxyscalcitrans), Drosophila flies (Drosophila repleta) and Blow flies (Lucilia, Phormia, and Calliphora) and black flies. The Lucilia species include L? cuprina and L? sericata(Axtell, 1999). Among these, the most common

The body condition scoring (BCS) is a subjective estimate of the energy reserves in adipose tissues of an animal. It is an acceptive, non-invasive, quick and inexpensive method to estimate degree of fatness. It is a means of accurately determining body condition of dairy cows, independent of body weight and frame size. It is evinced that the profile of lactating cows in milch barn is different e.g. some may be in early lactation and the others may either be in mid or late lactation. The observations on body condition status of animal will help the manager to adopt corrective management measures, thus enabling to improve the production profile of an animal. Hence, body condition scoring may be used as an efficient tool in this regard. Although many may consider this as a nutritional management practice, but changing BCS have implications on milk yield, health, reproduction, longevity and overall profitability of an animal. Body Condition Scoring (BCS) is a system used to evaluate the overall health and nutritional status of animals by 

Livestock production plays a critical role in global food security and economic sustainability. However, various stressors can significantly impact the well-being and productivity of livestock animals. Stress in livestock can arise from various sources such as environmental conditions, management practices, transportation, social interactions, and disease. Understanding the impact of stress on livestock production is essential for ensuring animal welfare and optimizing productivity. Although many factors can be involved, climatic factors are among the first and crucial limiting factors of the development of animal production in warm regions. In addition, global warming will further accentuate heat stress related problems in livestock. The first and foremost stress the livestock are exposed as a result of climate change is the heat stress. Among the environmental variables affecting animals, heat stress seems to be one of the intriguing factors making animal production challenging in many geographical locations in the world. Although animals can adapt to the hot climate, nevertheless the response mechanisms that ensures survival are also detrimental to performance. The vulnerability

Globally, the climate change is clearly evident in the form of changing weather pattern, and this has direct and indirect bearing on livestock production. Scientific evidence from multiple resources indicates that, without a doubt, climate is changing. It is also possible to suggest with increased confidence that climate is changing because of increased human activities which have serious repercussions on social and economic development. Greenhouse gases absorb heat from the sun in the atmosphere and reduce the amount of heat escaping into space. This extra heat has been found to be the primary cause of observed changes in the climate system over the 20th century. Livestock make a necessary and important contribution to global calorie, protein supplies and important micro nutrients such as B12, iron, calcium. They produce 17% of calories consumed globally and 33% of protein. Livestock can increase the world’s edible protein balance by transforming inedible protein found in forage into forms that people can digest. Climate change poses serious threats to livestock production. Various climate model projections suggest that by the year 2100, mean global temperature may be 1.1–6.4 °C

Introduction Handling and restraining is done to perform different management technique like drenching, dressing, vaccination etc safely, correctly, quickly and painlessly. Procedure • Handling should be done gently • Animal should not be shouted or beaten, always try to call/speak before touching. • Approach animal from behind and from their left side • Head and neck portion should be handled first • Always  have the owner or attendant along with you while handling strange animals Common appliances used in controlling animals 1. Rope: essential tool most often used for restraining animals. Cotton rope is preferred for strength, safety and easy to make knots 2. Halter: It is used as a least harsh of all restrain methods for animals. Halter are used to teach the animal to lead, to routinely handle them for day t

Introduction Identification of animals is must as a requirement in the daily management to spot and identify a particular animal in a herd/group/flock. Objectives of Identification • Identification is done to carry out routine work efficiently. • For registration and recording of the parentage in breeding programme / birth • Identification required at time of transportation and Insurance and loan from Bank. • For individual feeding of animals. • During milking • During sale, for participation of animals in the rally, show and exhibition. • For treating the animal, heat detection etc. • It is necessary for in case of theft and loss of animal for complain and search of animal. Selection of Identification Method • Depends very much on Need and personal

Introduction India’s animal husbandry sector plays a vital role in the country’s economy and food security. It provides livelihood to millions of people, contributes significantly to the agricultural gross domestic product (GDP), and meets the nutritional needs of the population. The sector encompasses various aspects of livestock production, including dairy farming, poultry farming, sheep rearing, goat rearing, and piggery. Milk Production India is the world’s largest milk producer, with an annual production of 230.58 million tonnes in 2022-23. This represents an impressive growth rate of 3.83% over the previous year. The top five milk-producing states are Uttar Pradesh, Rajasthan, Madhya Pradesh, Gujarat, and Andhra Pradesh. Egg Production India is also the third-largest egg producer in the world, with an annual production of 138.38 billion eggs in 2022-23. Egg production has grown by 6.77% in the last year. The top five egg-producing states are Andhra Pradesh, Tamil Nadu, Telangana, West Bengal, and Karnataka. Meat Production India’s meat production in 2022-23 was 9.77 million tonnes, with an annual growth rate of 5.13%. The top five meat-producing states are Maharashtra, Uttar Pradesh, West Bengal,

Diseases of livestock cause massive economic losses in terms of reduced productivity and production and some of them have zoonotic potential posing a serious risk to public health. Vaccination is the most efficient and cost-effective method of controlling infectious diseases both in humans and animals. The eradication of smallpox and rinderpest from the globe; the elimination of hog cholera and brucellosis from many countries; and the control of diseases such as foot-and-mouth disease, canine distemper, rabies, influenza, and pseudorabies would not have been possible without the use of effective vaccines. Vaccination not only protects the vaccinated animals but also reduces disease among non-vaccinated animals through herd immunity. They also reduce antimicrobial usage and minimize the risk of antimicrobial resistance. Vaccines Vaccines are prepared antigens to be used to prevent diseases caused by bacteria, viruses, fungi, mycoplasma, protozoa, and parasites.

Sometimes veterinarians have to deal with disease outbreaks and unexplained changes in herd production. In this situation, broad objectives of the clinician are:- i) To halt the progress of disease ii) To determine the reasons of outbreak iii) To recommend the procedures to reduce the risk of future outbreaks Terminology used in Disease Outbreaks The following terms are commonly used Outbreak - It defines as a sudden increase in the occurrences of a disease when cases are in excess of normal expectancy in the population for the location, season or species. It may affect a small and localized group or may affect a large number of animals. Epidemic- It has been described as an unexpected increase in the number of cases of a particular disease in a specific geographical area. In another words an epidemic is an rapid spread

Infectious diseases are illnesses caused by pathogens such as viruses, bacteria, fungi and parasites. Infectious diseases usually spread in animals through contact, contaminated food or water and through bug bites. Some infectious diseases are minor while others are very serious. Infectious diseases in the production animals are of great economic concern owing to losses though morbidity, mortality, reduced production, increased food insecurity, public health concern, increased cost of veterinary care etc. Therefore, prevention and control of infectious diseases of animals is very important for food security and safety, public health, animal welfare, access to market and alleviation of rural poverty. Key Factors for Effective Pevention and Control of Infectious Diseases The key factors for effectiveness of prevention and control strategies of infectious animal diseases are, (i) effective surveillance (active i.e. planned; or passive i.e. event based), (ii) an early detection of infection (making an early diagnosis with laboratory support), (iii) transparency and rapid response mechanism; and(iv) good governance.

Management of metabolic diseases depends on an early diagnosis. For an early diagnosis, metabolic profile test (MPT) is a diagnostic tool being commonly used in veterinary practice, particularly for dairy herds, to assess the metabolic health of the animals. It helps in an early detection by measuring various blood parameters that indicate the nutritional and health status of the cows for their effective timely management. MPT is based on the principle that the imbalance between input (feed) and output (production) is reflected in the abnormalities of key metabolites in the blood. Key components of the metabolic profile test 1. Energy balance indicators •     Glucose- Reflects energy status and carbohydrate metabolism. Low levels can indicate negative

Udder Health Mastitis is a significant and costly disease of udder affecting dairy cows and buffaloes, leading to reduced milk production, increased veterinary costs, and compromised animal welfare. Effective udder hygiene practices are crucial in preventing and controlling mastitis, maximizing milk production, ensuring animal welfare, minimizing costs, and maintaining consumer trust. By focusing on udder health management through preventative measures and the best practices, dairy farmers can enhance the overall sustainability and profitability of dairy operations. There are six major steps that can lead to a better udder health. •     Farm hygiene and udder hygiene •     Hygienic milking procedure •     Dry cow management and therapy •     Appropriate therapy for mastitis cases during lactation •     Culling chronically infected cows. •     Good nutrition to increase the udder resistance to mastitis Farm hygiene and udder hygiene

Peri-parturient Health Care Periparturient period is defined as a period immediately around calving. It is the most critical time when high yielding cows are prone to nutritional deficits due to great metabolic alterations from dry to milking. Reduced feed intake and depressed immune system at this time make cows vulnerable to periparturient diseases affecting milk yield adversely and increasing mortality risk. Health care during this critical period aims at minimising deficits particularly in relation to dry matter intakes (DMI’s) and energy and mineral balance. •     Milk fever is the most common and important periparturient disease affecting high yielders. Due to the sudden onset of lactation, there is a huge demand for calcium resulting in dramatic decrease in blood calcium level during calving causing milk fever.

Herd A large number of animals that live and feed together in a group (Fig.197) is called as herd. In herd, all animals are considered as a unit rather than individual. Herd medicine, also known as herd health or production medicine, is the discipline of veterinary medicine that deals with the diagnosis, treatment and prevention of the diseases in the herd as a whole. Concept and Significance of Herd Health Herd health is a combination of regularly scheduled veterinary activity and management practices undertaken to maintain optimum health to achieve optimum production in the farm. Traditionally, the aim of the herd health is to control or eliminate diseases and rectify management inefficiencies impacting the welfare and productivity in the frame work of risk monitoring and assessment in conjunction with best farming practices. The main emphasis

Endoscopy is a minimally invasive procedure that allows the clinician to look within a hollow organ or body cavity and obtain diagnostic information, which includes grossly evaluating an area of interest and obtaining tissue for histopathologic evaluation. Endoscopy is also used for therapeutic purpose and termed as interventional endoscopy. Endoscope An endoscope is basically consists of an insertion tube, hand piece and umbilical cord, Insertion tube -Encases the mechanism for image transmission. It consists of fiberoptic glass bundles (fiber-scope) or charge coupled device (CCD) chip (video endoscope), biopsy/suction channel, irrigation/insufflation channel and deflection control cables. Handpiece – It includes deflection control knobs,accessory channel entrance, irrigation/insufflation and suction valves.

Ultrasonography, popularly known as sonography, is a non-invasive, radiation free and safe medical procedure being increasingly used for the imaging different body organs/ structures for the diagnosis of various diseases not only in humans but also in farm, companion and exotic pets. The technique involves ultrasound unit, patient and doctor/veterinarian (trained in sonography). Ultrasound Unit Ultrasound unit has processor (central processing unit commonly known as CPU), transducers, key board, data storage and printer (Fig. 187). •     The CPU (central processing unit) is basically a computer having microprocessor, memory, amplifiers and power supplies for the microprocessor and transducer. The CPU transmits electrical currents to the transducer to emit sound waves, and receives the returning echoes. Returning echoes are processed to form the image on the monitor. The processed data and/or image are

Fluid therapy is a critical intervention in Veterinary Medicine, requiring careful assessment and monitoring to ensure effectiveness and to minimize risks. Tailor made individualized approach is essential for optimal outcome. Fluid Therapy in Small Animals Indications •     Most common indication for fluid therapy is correction of dehydration and resuscitation from shock, hypokalemia, and metabolic acidosis. •     Less common indication for fluid therapy is in cases of acid-base disturbances (metabolic alkalosis or mixed acid-base disturbance), specific correction of other electrolyte disturbances such as sodium, potassium, calcium, magnesium. •     Other indication for fluid therapy is for the treatment of anemia and coagulopathies. Body fluid compartmentalization •     Total body water (TBW) in adults is approximately 60% of body weight. While young animals (neonates 80% and pediatrics 75%) contain more water. Water is located in separate yet

Blood transfusion is one of the crucial life-saving procedures in veterinary medicine undertaken to increase red cell mass, volume replacement, replenishing coagulation factors, and protein replacement. The concept of blood transfusion was first introduced by Francis Potter in 1639. However, it was only in 1666 that Richard Lower reported the first successful direct transfusion from one dog to another. Blood is a biological drug and is not a definitive treatment, but it provides support until the disease is diagnosed or treatment is initiated. Indications Blood transfusion is indicated for the management of the following conditions: •     Anemia due to various diseases/disorders, like infection or acute/ chronic hemorrhage •     Bleeding disorders such as thrombocytopenia or coagulopathies •     Rodenticide toxicities

The skin is the largest organ in the body. It not only defends the body but also assists in the maintenance of homeostasis including water conservation and in body temperature conservation through insulation and in heat loss through perspiration. Pain and temperature extremes are recognized through sensory nerves of the skin. The skin also provides protection against physical injuries to some level, supports hair growth and offers some defence against microbial invasion. Skin diseases are multifactorial in etiology. But the response of skin to varying etiological stimulus is limited leading to same clinical manifestations in different skin diseases. Therefore, a comprehensive clinical examination is necessary for accurate diagnosis of the disease. Clinical Examination The clinical examination of skin diseases involves a systemic approach including history, physical examination and diagnostic testing. History

Proper restraint and handling of laboratory and exotic pets reduces stress for both animal and examiner. Handling-related stress introduces a variable into experiments, so its minimizing is essential. Improper handling can lead to significant injuries for both animals and humans. Laboratory Animals General Care •     A healthy and regularly behaving animal is in a state of well-being. Maintaining the state of wellbeing requires effective health management and appropriate exercise. •     New animals on arrival should be quarantined, carefully examined, and placed in clean cages. Shipping containers should not enter the main facility and must be discarded. Proper identification and documentation of each animal, including details like origin and condition, is essential. Any sick animals should be euthanized immediately. •     Animals should be housed in separate rooms

Restraint Various techniques and equipment are employed to capture and restrain both zoo and free-ranging wild animals for physical examinations and medical treatment. The primary methods of restraint are physical and chemical restraint. Assessing the physical condition of the animal and determining the necessity of capture are essential, as all restraint methods can impact an animal’s behavior, physiology, and response to medication. Certain animals, such as black bucks, chinkaras, and deer, are particularly sensitive to restraint and prone to thermoregulatory issues, capture myopathy, and shock. In these species, even a routine capture can lead to injury or death. Terminology The following terminology is generally used during restraints of wild animals. Anesthesia: Causes unconscious with loss of awareness and pain relief. Analgesia: A state in which pain and sensation are effectively blocked.

The udder is responsible for milk production. It is composed of four mammary glands each with its own teat (Fig. 167). Swelling of udder or teats is an indication of udder disease warranting clinical exploration and palpation. Visual examination the udder (before and after milking) and palpation is of great significance in detecting abnormalities. The udder is visually inspected from back and sides for symmetry and also palpated thoroughly. Palpation is a simple, quick and easy routine diagnostic tool for mastitis detection. Teats and supra mammary lymph nodes should also be palpated. These examinations aid in detecting fibrosis, inflammation or atrophy. Diffuse fibrosis gives the quarter a firm feeling. Areas of local fibrosis may vary in size and shape. Hot, painful and diffuse swelling with marked abnormality of mammary secretion is seen in acute mammary inflammation (acute mastitis). Atrophy of the gland is the terminal stage of chronic mastitis. With the development of gangrene, the area becomes cold and bluish. Five point palpation scores (Petrovski et al., 2011; Hogan et al., 1995; Scaletti and Harmon, 2012)

Bone marrow is a soft, gelatinous tissue that fills the medullary cavities of bones. It plays a crucial role in the production of blood cells. It makes up about 3% of body mass in rats, 2% in dogs, and 5% in humans. Bone marrow develops in the embryo during the second trimester of pregnancy. This tissue is vital because it contains stem cells that can differentiate into various cell types. Bone marrow is of red and yellow types. In young mammals, the marrow is red and active (with minimal fat). With aging, accumulation of adipose tissue, and long bones transition turn bone marrow to yellow, fatty, inactive. In adult mammals, active hematopoiesis continues in flat bones, such as the sternum, ribs, pelvis, vertebrae, and skull, as well as the epiphyses of long bones. Erythropoiesis in these regions contributes significantly to red blood cell production, with the axial skeleton accounting for about 35% and the appendicular skeleton for 65%. In birds, hematopoiesis is mainly restricted to bone marrow, while in reptiles, it occurs in the bone marrow, spleen, liver, and thymus. Indications

Lameness in dairy animals is a serious health problem all over the world causing substantial economic losses to dairy industry owing to reduced milk production, reduced reproductive performance, cost of treatment including medicines, increased risk of culling, death, and the development of other diseases. Lameness can be defined as a state of being unable to walk properly because of pain in the limbs or foot. The incidence of lameness in the dairy herd is variable (1 to 50%) depending on the farm. In USA its incidence varies from 13 to 55% (Hoffman et al., 2014; Cook et al., 2016). Lameness may be due to diseases of limb and/or hoof of infectious and/or noninfectious origin. Lameness usually affects hind limbs because of greater load of the body on hind limbs. A lame animal adjusts gait and posture depending on the origin of the pain (foot or upper limb). Clinical signs of lameness include changes in locomotion (e.g. decreased speed, decreased stride, length and tracking, increased abduction,

Musculoskeletal system consists of muscles, cartilage, bones, joints ligaments and tendons. Primary function of the musculoskeletal system is to support the body, helps in mobility, and protects vital organs of the body. Diseases of these organs have clinical manifestations such as lameness, failure to support weight, inefficient joint movement and deformity. Examination of musculoskeletal system includes general as well as special examination. General examination consists of examination of posture in sitting/recumbency, standing position and while rising; examination of gait; and any other abnormality. General Examination The animal is observed for conformation (outline and shape), symmetry and posture in standing position from the cranial, caudal and lateral positions. Asymmetrical shape of the body or limbs may be due to swelling that should be examined by palpation,

Large Animals The collection and evaluation of cerebrospinal fluid (CSF) in farm animals with signs of diseases of nervous system provides very valuable diagnostic and prognostic information. Routinely, CSF is evaluated for total protein level, erythrocyte and leukocyte counts, and a differential cell count. Additional tests are available for specific neurologic conditions. CSF is primarily produced by the choroid plexuses in the lateral, third, and fourth ventricles through plasma ultra filtration and active transport across the blood-brain barrier. Smaller amounts of CSF are generated by the ependymal lining, pia arachnoid, meningeal blood vessels, and spinal cord’s central canal. The turnover rate is about 1% per minute, meaning systemic electrolyte or acid-base changes take several minutes to affect CSF
