“Where is your Dhoti, Dr. Mehta ?” Dr. Varghese Kurien surprised me as I entered his office at IRMA (Institute of Rural Management Anand). That was April 2000, soon after I had taken over as the Vice Chancellor of the erstwhile Gujarat Agricultural University (GAU) and had decided to call on him during my visit to the Anand Campus. (At that time GAU was the largest University in Asia with four main campuses – Dantiwada, Anand, Junagadh and Navsari and about 65 experimental farms / stations spreaded all over). Earlier, I did have some interactions with Dr. Kurien. When at GSFC Ltd., we had introduced Nylon – 6 Engineering plastic. I had discussed with my team of Research and Application Development Engineers about multi layer packaging of dairy products where Nylon – 6 can have a good market potential which we used to discuss with Amul. Also, our work on Bio Fertilizers and Bio Pesticides had indirect interest to them. So, when suddenly I was offered the position of Vice Chancellor of GAU and was in a dilemma, I went for his advice. After all, he had held the same position earlier (in addition to AMUL). I explained about the offer and said that I was not too sure about accepting it. He, on the contrary, encouraged me to accept it saying “you can do a lot !” I just murmured,” But I am not an agriculture graduate. I am a Chemical Engineer!” To which he jokingly said – “So ?. I am a Metallurgical Engineer. And now I am a Dudhwala!”

In contrast to the traditional universities, agricultural universities have been entrusted with the Herculean task of technology dissemination at the grass root level such that the package of practices evolved by the agricultural scientists should reach out the end-users, viz. farmers , for adopting in the field, with consequent increment in the farm productivity and farmer’s income. This unique mandate has been assigned to agricultural universities on the pattern of land grant colleges of the United States. Such vision and trust, envisaged by Pandit Jawaharlal Nehru and his devout lieutenants, herald creation of state agricultural universities (SAUs) in the early 1960s. The key role played by SAUs in the first green revolution and agricultural human resources development have been regarded as the milestones in the history of India post-independence, that made the country self-sufficient in food production and, in turn, to self reliance in milk, vegetables, fruits and inland fish production. Today, India has set fourth into commanding position as a global economic power, with primary and secondary sectors, viz. agriculture and industry, contributing modestly. At the current pace of the growth rate, I would not hesitate to predict that by the year 2020, we will accomplish the top lines both in terms of productivity and sustainability, by transforming hitherto deemed liability of population into a formidable asset of human resource capital.
Hunger-free World
Agriculture is a vital development tool for achieving the Millennium Development Goals that call for halving by 2015 the number of people, suffering from extreme poverty and hunger. We also note that more than 50% of the people in the world are small and resource-poor farmers and another 20% rural land less. The challenge is to transform this

It is well understood that the impact of climate change on agriculture and food security will be critical. The variation in climate influences the productivity of crops, livestocks and fisheries.
The major points to remember are
Climate changes are increasingly impacting agriculture and food security adversely.
Cereal productivity may decrease by 10 – 40% by 2100.
Negative effect on livestock productivity and increased disease.
Achieving Millennium Development Goals (MDG) will become more difficult.
Further, it is also estimated that : Cost of Climate Change will be equivalent of loosing 5 to 20% of GDP (N. Stern : World Bank).Sustainable Agriculture practice could absorb a third of the CO2. Globally, about 800 m $ / day is spent on direct / indirect subsidies. Among other things, it is suggested that encouraging Eco Agriculture is the way out. We must transform 1.5 b ha into Eco / Agri Farming. Small farmers to play BIG role. At the COP28 summit in Dubai, food and agriculture declaration was signed by over 130 world leaders on Sustainable Agriculture and a commitment to mobilize over $2.5 billion to tackle climate issues related to agriculture
COP and 4 per 1000 initiative
Conference of the Parties (COP) to the UNFCC (United Nations Frame Work on Climate Change) has been making significant efforts to mitigate the adverse climate change efforts. At COP 21 in Paris, a landmark agreement was reached to combat climate change and accelerate actions for sustainable low carbon future. COP 22 at Morocco will focus on short, medium and long

After the Green Revolution, it is now time for an Ever-Green Revolution based on Eco Agriculture or Agroecology. In 2018, the FAO described Agroecology/Eco Agriculture as a means to transform food and agriculture systems by addressing root causes and emphasizing the improvement of efficiency in resource use, conserving, protecting and improving livelihoods, promoting equality and well-being and enhancing the resilience of people, communities and ecosystems. A timely transition to a sustainable eco-agriculture approach is essential to protect food security, the well-being of people and farmers prosperity. Eco Agriculture is a broad term that can inclusively refer to agroecology, regenerative, organic, natural, jaivik, etc, and is increasingly being recognized as the way to help save the planet. While discussing this with Prof Swaminathan and the ICFA team, the idea of a Working Group emerged. When I was requested to form the Eco Agri Working Group through ICFA, I consulted with different sectors and tried to determine the “why” and “how” of the impending Eco Agri Revolution.
WHY
The past sixty years led to Green Revolution and alongwith that ‘success’ several adverse impacts and the changing global situation as noted in Table – 1 are the reasons for the need for an Evergreen Revolution based on Eco Agriculture

Drought, characterized by prolonged periods of abnormally low rainfall, is a recurring and devastating natural phenomenon with profound implications for global agriculture. Among the sectors most vulnerable to the adverse impacts of drought is livestock production. This chapter, “Droughts and Livestock Production,” delves into the intricate relationship between these two critical elements, exploring the multifaceted challenges and consequences that drought poses to livestock farming across diverse geographical contexts The chapter will examine how water scarcity, a hallmark of drought, disrupts the delicate balance of feed availability, animal health, and overall productivity within livestock systems. It will further analyze the varied impacts of drought on different livestock species, considering their unique physiological needs and vulnerabilities. Beyond the immediate 

Advertising has long been a powerful tool for businesses to communicate with their target audience, influence consumer behavior, and build brand awareness. While digital marketing has gained prominence in recent years, traditional advertising remains a fundamental part of marketing strategies. Traditional advertising encompasses a range of media channels such as television, radio, newspapers, magazines, billboards, and direct mail. This chapter explores the various aspects of traditional advertising, its effectiveness, advantages, and challenges in the modern marketing landscape.
Evolution of Traditional Advertising
Traditional advertising has evolved significantly over the years. In the early days, businesses relied on word-of-mouth, signage, and posters to promote their products and services. With the advent of mass media, advertising took new forms:
• Print Advertising: One of the oldest forms of advertising, print media includes newspapers, magazines, brochures, and flyers. Businesses have historically used print ads to reach a broad audience.
• Radio Advertising: The introduction of radio in the early 20th century revolutionized advertising by allowing businesses to broadcast their messages to a vast audience.
• Television Advertising: The mid-20th century saw the rise of television commercials, providing businesses with an engaging and visually appealing way to market their products.
• Outdoor Advertising: Billboards, posters, and transit ads have been used to attract consumers in high-traffic areas.
• Direct Mail Advertising: Sending promotional materials directly to consumers’ homes has been an effective marketing strategy for decades.

Advertising is a crucial component of marketing, designed to promote products, services, or brands to target audiences. A well-planned advertising strategy enhances brand visibility, attracts potential customers, and drives sales. Various advertising strategies exist, each tailored to achieve specific business objectives and cater to different market segments. This chapter explores the different types of advertising strategies used by businesses to maximize their reach and impact.
1. Print Advertising: Print advertising involves placing ads in newspapers, magazines, brochures, flyers, and billboards. It is a traditional form of advertising that continues to be effective for local and niche markets.
Advantages
• Tangible and long-lasting: Print materials can be kept for future reference.
• Targets a specific readership: Newspapers and magazines cater to specific demographics.
• Builds brand credibility: Established publications lend trustworthiness to ads.
Disadvantages
• Declining readership: With digital media gaining traction, fewer people rely on print.
• Expensive for premium placements: High visibility ads cost significantly more.
• Limited tracking capabilities: Hard to measure direct impact and ROI.
2. Broadcast Advertising: Broadcast advertising includes television and radio commercials. It is one of the most powerful advertising methods due to its broad reach and audio-visual appeal.
Advantages
• High engagement with audiences: TV and radio captivate viewers and listeners.

Introduction
Cleavage is the process of cellular division without growth. It is also called segmentation division and it follows immediately after fertilization. By the end of this process, single cell zygote is transformed into multi-cellular stage called blastula. Daughter cells are called blastomeres. All divisions are mitotic and occur consequently. Ratio of nucleus to cytoplasm is very low at beginning but later they resemble somatic cell. Cleavage division always start at animal pole. Cleavage can be classified as:
1. Holoblastic/Total cleavage: Whole fertilized ovum is involved in production of blastomere. It is also called complete cleavage.
a) Equal: All blastomeres are of equal size. E.g. mammals
b) Unequal: Some blastomeres at vegetal pole are larger. E.g. amphibians
2. Meroblastic/Partial cleavage: When deutoplasm is abundant and only a part of fertilized ovum is involved in cleavage, it is called meroblastic cleavage.
a) Discoidal: Cleavage is confined to the germinal disc i.e. at animal pole. E.g. birds and reptiles.
b) Superficial: Cleavage is confined to the peripheral margin of cytoplasm. E.g. arthropods.
Dividing continuously, embryo attains a stage of 16-32 cells. 16-celled stage is called early/uncompact morula and 32-celled stage is called compact morula. This stage is called morula due to its close resemblance to mulberry fruit. Structure is surrounded by zona pellucida.
After morula stage, fluid accumulation begins and blastomeres are gradually pushed to the periphery. As fluid accumulation progresses further, it leads to formation of large cavity in central part of embryo known as blastocoels and morula stage is now transformed into blastula/blastocyst stage. Blastomeres now arrange themselves as single celled outer layer called trophoblast and small group of cells at animal pole called inner cell mass (ICM). Trophoblasts give rise to fetal membranes and will help embryo in its attachment to uterine wall (implantation). ICM gives rise to all organs of body. Development of blastula is called blastulation.

The formation of the mammalian body plan is regulated by highly conserved gene regulatory networks. During this developmental stage, the notochord and primitive node play critical roles in establishing the cranial-caudal axis and left-right asymmetry. Ectoderm, the outer germ layer, differentiates into neuroectoderm and surface ectoderm. Neuroectodermal cells move from the developing neural tube’s lateral edges to a dorsolateral position. These neuroectodermal cells are known as neural crest cells. The central nervous system originates from the neural tube, whereas the peripheral nervous system originates from both the neural tube and the neural crest. Mesoderm cells proliferate and develops into three separate components: the paraxial, intermediate, and lateral plate of mesoderm. The paraxial mesoderm cells form whorl-like aggregations known as somitomeres on both sides of the neural plate. Paraxial mesoderm organises into separate blocks known as somites caudal to the seventh somitomere. Somatic cells make up the vast majority of the axial skeleton, accompanying muscle, and covering dermis. The embryonic gut tube, developing respiratory system, and accompanying glands all develop from endoderm, the inner germ layer. Endoderm is also responsible for the epithelial linings of the urinary bladder, middle ear, and auditory tube. Endoderm also gives rise to the parenchymal cells of the thyroid, parathyroid glands, pancreas, and liver.

Introduction
The nervous system is an intricate network that plays a crucial role in coordinating and regulating bodily functions, allowing organisms to interact with their environment. This complex system is fundamental for the existence, enabling to sense the world, process information, and respond to stimuli. Comprised of billions of specialized cells called neurons. The nervous system is responsible for various functions, from reflex actions to complex thought processes. The nervous system is a highly organized and complex network that serves as the primary means of communication within the body of all animals, including domesticated species. Understanding the anatomy and function of the nervous system is critical in veterinary medicine, as it governs essential processes such as locomotion, sensation, cognition, and homeostasis. Comprising the central nervous system (CNS) and peripheral nervous system (PNS), the nervous system enables the coordination of reflexes and voluntary movements, facilitating interactions with the environment. Structural Organization: the CNS is composed of the brain and spinal cord, which are protected by the bony encasement of the skull and vertebral column, respectively. The brain varies significantly across species, reflecting adaptations to specific ecological niches and behaviors. For instance, the canine brain shows notable development in areas associated with olfaction, whereas the equine brain has adaptations for vision and balance, crucial for flight responses. The spinal cord serves as a conduit for neural signals between the brain and the peripheral nerves. It is organized segmentally, with spinal nerves emerging from specific regions. This segmentation corresponds to the vertebral column and is vital for diagnosing spinal cord injuries and diseases in animals. Each spinal nerve innervates specific muscle groups and areas of the skin, forming a somatic map essential for clinical examination and treatment. Neurons and Neuroglia: Neurons are the functional units of the nervous system, specialized for the transmission of electrochemical signals. In veterinary anatomy, it is essential to understand the structure of neurons, which includes the cell body, dendrites, and axon. Neurons can be classified into various types—sensory (afferent), motor (efferent), and interneurons—each playing distinct roles in reflex arcs and neural circuits. Neuroglia, or glial cells, provide support, nourishment, and protection for neurons. In veterinary practice, the role of glial cells in pathology is increasingly recognized, particularly in conditions such as neuroinflammation and neurodegeneration. For example, astrocytes play a crucial

Introduction
Assisted reproductive technology (ART) refers to treatments and procedures in the field of reproductive biology that are utilised to achieve pregnancy by artificial or partially artificial means.
Artificial insemination
Artificial insemination (AI) is the earliest form of assisted reproductive technology. The technology has been of immense relevance in enhancing production and health features through the appropriate use of better male animals, as well as in eliminating certain venereal illnesses.
• Semen collection: The man is typically allowed to mount a phantom during the process. In cattle, an artificial vagina is used)
• Semen evaluation: Evaluating semen is crucial before processing. The most basic semen evaluation involves examining the concentration, progressive motility, and morphological normality of the spermatozoa)
• Semen dilution, packaging and freezing: Following examination, the semen is ready for dilution and packaging. Spermatozoa require storage mediums that are particular to each species. After packaging, the semen dosages must be properly maintained until insemination. Cryopreservation is typically used for cattle.
• Insemination: Insemination should occur during the female’s oestrus, when she is receptive to copulation.
Multiple Ovulation and Embryo Transfer (MOET)
The main processes are to stimulate a donor female to create suitable embryos, then remove the embryos from her and transfer them to unmated recipient females at equivalent post-ovulatory reproductive phases, ensuring that the donor’s embryos are carried to term in the recipients’ uteri. Multiple ovulations are caused by superovulation or superstimulation, a procedure that increases the number of ovulations in a donor beyond what is normal for a given species. Embryos are recovered 6-8 days following the start of oestrus. Most embryos are transferred during the late morula or blastocyst stage.

Entrepreneur
The term “entrepreneur” originates from the French word meaning “to undertake” or “to do something.” It was first introduced by Richard Cantillon in 1755, who described an entrepreneur as an agent who procures factor services at fixed prices with the aim of selling the resulting product at uncertain future prices. Joseph Schumpeter later expanded the concept, portraying the entrepreneur as an innovator who fosters economic development by introducing new products, discovering new markets, sourcing raw materials, and establishing novel organizational structures within industries. Schumpeter emphasized profit as the outcome of innovation and a driving force behind economic growth.
Entrepreneurship
Arthur Cole defined entrepreneurship as a deliberate activity undertaken by an individual or a group to initiate, sustain, and enhance profit through the production or distribution of economic goods and services. Entrepreneurship also encompasses the ability to foresee investment and production opportunities, organize and manage enterprises to adopt new production methods, secure capital, hire labor, arrange raw material supply, identify suitable locations, implement innovative techniques, discover new resources, and appoint top-level managers for the daily operations of the business.
Successful Entrepreneurs’ Characteristic Features
Entrepreneurship and Small Business Development (NIESBUD), New Delhi, describes an entrepreneur as an individual who blends innovation, risk-taking ability, the capacity to recognize opportunities, the skill to mobilize resources, a drive for excellence, and persistent dedication to achieving goals.

A project network is a graphical representation of the sequence and interdependencies of activities or tasks in a project. It is used to plan, schedule, and manage projects effectively. Here are some key concepts and techniques related to project networks:
1. Project Network Diagram
• Activity-on-Node (AON): Represents activities as nodes and arrows as dependencies. For example, a node might represent a task, and arrows show the order in which tasks must be completed.
• Activity-on-Arrow (AOA): Represents activities as arrows and nodes as events. This method is less common than AON.
2. Techniques for Project Network Analysis
• Critical Path Method (CPM): Determines the longest path through the network, which defines the shortest possible project duration. The critical path identifies tasks that cannot be delayed without affecting the project’s completion date.
• Program Evaluation and Review Technique (PERT): Focuses on analyzing and representing the tasks involved in completing a project. It includes probabilistic time estimates (optimistic, pessimistic, and most likely) to account for uncertainty.
• Gantt Chart: A bar chart that represents the project schedule. Each bar represents a task, and its length represents the duration. It helps visualize the start and end dates of tasks and their overlaps.
• Precedence Diagramming Method (PDM): A technique for constructing project network diagrams. It involves defining the logical sequence of activities and their dependencies.
• Resource Leveling: Adjusting the project schedule to account for resource constraints, ensuring that resources are used efficiently without overloading.

The increasing global emphasis on sustainability and the circular economy has brought renewed focus to the valorization of agri-biomass and organic waste—the process of converting low-value, often discarded residues into highvalue products. Agricultural biomass, including crop residues such as straw, husks, and stalks, along with organic waste like food scraps, animal manure, and agro-industrial by-products, is both abundant and underutilized, particularly in developing regions. Traditionally, these materials have been disposed of through open burning, landfilling, or natural decomposition, all of which release significant quantities of greenhouse gases and contribute to environmental degradation. However, recent innovations in green technology and material science are transforming these waste streams into valuable resources. Through processes such as pyrolysis, fermentation, and biochemical conversion, agri-biomass and organic waste can now be converted into biochar, bio-based chemicals, and sustainable biomaterials. These products not only mitigate environmental harm but also create new economic opportunities across agriculture, industry, and the renewable energy sector. By leveraging these advancements, societies can significantly reduce waste, lower emissions, and accelerate the transition to a more sustainable and circular bioeconomy.

As the world faces mounting environmental challenges, resource scarcity, and the need to shift toward a low-carbon economy, sustainable waste management and alternative energy solutions are gaining critical importance. In this context, agri-biomass and organic waste valorization has emerged as a transformative area—addressing both the disposal of agricultural residues and organic waste, while enabling the generation of clean energy, bio-based materials, and high-value products.
Advanced Valorization Technologies
The field is rapidly evolving beyond traditional methods such as composting and combustion to adopt biochemical and thermochemical processes. Technologies like:
• Anaerobic digestion for biogas,
• Fermentation for bioethanol and organic acids,
• Pyrolysis for bio-oil and biochar,
• Gasification for syngas production,
Are increasingly supplemented by next-generation approaches like hydrothermal carbonization, microwave-assisted pyrolysis, and supercritical fluid extraction. These are tailored for India’s diverse agri-residues—rice straw,
sugarcane bagasse, coconut husk, and more—making them scalable across regions.
Importantly, these technologies now aim for value maximization, producing bioplastics, nutraceuticals, soil enhancers, and even sustainable construction materials.

1.1 Introduction
The rural economy has greatly benefited from dairy farming. In rural India, milk has become a substantial source of revenue. Dairy products, including milk, are vital components of modern diets. India holds the title of being the greatest milk producer and consumer globally. Together with native cattle, crossbred cattle, and water buffalo, it also has the biggest dairy herd. Since 2000, there has been a steady and substantial annual growth rate of 4.2 percent in both milk production and consumption. Additionally, second, respectively, in terms of population (GoI, 2014). It accounts for around 25% of the global bovine population. India has emerged as the leading global producer of milk, with a remarkable production of over 155.5 million tonnes during the 2015- 16 period. This translates to a per capita availability of 337 grammes per day, according to the Government of India (GoI, 2017). Dairy farming serves as a primary means of subsistence for more than 100 million individuals. A significant percentage of small-scale livestock keepers lack access to land, and the prevalence of rural landless households is expected to rise due to the continued subdivision of land holdings. Livestock are increasingly vital for the income of smallholder and landless farmers. These initiatives have positively impacted the farmers’ food production, nutrition security, and household income. Additionally, they have played a crucial role in creating employment opportunities in rural areas.

9.1 Introduction
The term “pasteurisation” is derived from the Frenchman Louis Pasteur, who demonstrated that the preservation of wine was enhanced by heating it to a temperature of 122 to 140 °F, which eradicated spoilage organisms. This occurred between 1860 and 1864. The utilisation of this procedure resulted in the development of a new term, “pasteurisation,” which rapidly acquired popularity in the field of technology. Although Louis Pasteur was a pioneer in the discovery of the use of thermal treatment to preserve wine, the process of pasteurising milk was initially attributed to Dr. Soxhlet of Germany in 1886.

9.2 Heat treatment of milk
In the context of market milk, pasteurisation is currently defined as the process of heating each component of milk to a minimum of 63°C for 30 minutes, 72°C for 15 seconds, or any other temperature and duration that achieves the same level of effectiveness. Equipment that has been certified and functions properly is required for this process. The milk is promptly chilled to a temperature of 5°C or lower after the pasteurisation procedure.

21.1 Introduction
Khoa, as well as mawa or khava, is a partially dehydrated whole milk product that is produced by perpetually heating milk in a karahi over a direct fire while stirring and scraping it with a khunti until it reaches a semi-solid consistency. The pan is removed from the fire once the desired consistency is obtained, and the contents are transformed into a solid mass known as khoa pat. “Khoa is produced by rapid drying cow, buffalo, goat, or sheep milk, or a combination thereof, and must contain a minimum of 20% milk fat.The product is produced by heat desiccating milk to 65–69% solids in an open pan. Khoa has been utilised as a foundation for Indian desserts for centuries. Milk traders and halwais prepare it according to the conventional procedure. You typically require five times the amount of milk content.

21.2 Classification
There are three primary varieties: “pindi” for burfi, “dhap” for gulab jamun, pantooa, and other delicacies, and “danedar” for kalakand. Khoa production has been the most straightforward technique of preserving milk produced in rural areas during the flood season. Pindi, dhap, and Danedar are the three primary varieties of khoa that are prepared throughout the country. Khoa is the foundation for a diverse array of Indian delicacies, such as gulab jamun and other dishes.

26.1 Introduction
Developed nations’ packaging sector has achieved great advancement. The advent of innovative marketing strategies such hyper markets and selfservice outlets has pushed the packaging technologies in these nations to unprecedented heights. The evolution of appliances and packaging tools as well as the introduction of fresh and better packaging materials has happened holistically. In nations like India still in development, packaging is still in its infancy. Packaging any product is the arrangement of the most appropriate containers and components to safeguard, move, label, and identify any good.
26.2 Packaging
Packaging is putting an item into a protective wrapping or container for use or storage. The package serves three purposes: it stores, shields, and merchandising tool. For the safe delivery of the product through the several phases of manufacturing, storage, transportation, distribution, and marketing, it is a necessary link between the manufacturer and ultimate customer. Fresh, sound and easy form of milk delivery depends on protective packaging to minimise losses and withstand the challenges of climate change, transit, handling etc.
1. To contain the product: The package should be big enough and built with suitable elements to stop spoiling and leaks. It should be sturdy enough to withstand handling, shipping, and storage difficulties as well as closely matched with the product.
2. To protect the product: Packaging seeks to protect the product from microbiological activity, heat, light, moisture, oxygen, evaporation, etc., therefore preventing contamination, loss, damage, or degradation.
3. To help in selling the product: Easy dispensing, reclosure, disposal, and possible reuse should be made possible by the packaging form, therefore helping the marketability of the product.

Weather parameters, such as temperature, humidity, rainfall, and wind, play a significant role in the epidemiology of viral diseases in crops. Viral diseases, caused by viruses that infect plants, can have devastating effects on crop yields and quality, leading to significant economic losses for farmers and the agricultural industry. The impact of weather parameters on viral diseases is complex and multifaceted. Weather conditions can influence the spread of viruses, the survival and multiplication of virus vectors, and the susceptibility of plants to virus infection (Fig. 9.1). Understanding the relationships between weather parameters and viral diseases is essential for developing effective disease management strategies and mitigating the impacts of viral diseases on crop productivity. Fig. 9.1. Yellow Leaf Curl Viral disease of Tomato Temperature, for example, can affect the replication and transmission of viruses, with optimal temperatures varying depending on the specific virus, its vector and host plant. Humidity and rainfall can influence the spread of viruses by affecting the movement and behavior of virus vectors, such as insects and nematodes. Wind can also play a role in the spread of viruses by dispersing virusinfected pollen and insects. This chapter will explore the effects of weather parameters on viral diseases in crops, with a focus on the relationships between temperature, humidity, rainfall, wind, and viral disease epidemiology. By examining the complex interactions between weather parameters and viral diseases, we can gain a deeper understanding of the factors that contribute to the spread and impact of viral diseases in crops, and develop more effective strategies for managing these diseases.

Weather forecasts play a crucial role in disease control measures for crops. By providing advance warning of favorable conditions for disease outbreaks, weather forecasts enable farmers to take proactive measures to prevent or mitigate the impact of diseases on their crops. This approach is particularly important in modern agriculture, where crop diseases can have devastating effects on yields and quality. The relationship between weather conditions and crop diseases is complex, with factors such as temperature, humidity, rainfall, and wind direction all playing a role in the development and spread of diseases. For example, high humidity and rainfall can create ideal conditions for fungal diseases, while warm temperatures and dry conditions can favor the development of bacterial diseases.By analyzing weather forecasts, farmers can identify periods of high disease risk and take steps to protect their crops. This might involve applying fungicides or bactericides, adjusting irrigation schedules, or implementing other cultural controls to reduce the risk of disease outbreaks (Fig. 12.1). In recent years, advances in technology have improved the accuracy and availability of weather forecasts, making it easier for farmers to access the information they need to make informed decisions about disease control.Additionally, the development of predictive models that incorporate weather data, crop phenology, and other factors has further enhanced the ability of farmers to anticipate and manage disease outbreaks . Overall, the use of weather forecasts in disease control measures is a critical component of integrated disease management (IDM) strategies, which aim to minimize the economic, environmental, and social impacts of crop diseases. By leveraging advances in weather forecasting and predictive modeling, farmers can reduce their reliance on chemical controls, promote more sustainable agricultural practices, and improve the overall health and productivity of their crops.

The word “Veterinary” has originated from Latin “veter?n?rius” concerning draught animal and “Medicine” from Middle English, Middle French, Old French and Latin words meaning “healing”. Veterinary medicine is the offshoot of the medicine dealing with the diagnosis, treatment and prevention of diseases/disorders of all animal species including domestic, wild and exotic, companion, draught and pack animals. CONTRIBUTION OF VETERINARY MEDICINE • Reduction in number of cases of tuberculosis and brucellosis in human. • Development of safe and effective vaccines to prevent and control of animal diseases such as Rinderpest, Foot and mouth, Hemorrhagic septicemia, Black quarter,  Pox, Parvo, Distemper,

Medication refers to administration of drugs. The route, dose and frequency of the drugs administration is most important in providing health care and welfare of the animals. Wide range of body size and their weight in animals and rearing practice makes the treatment and drug administration strategies a bit complex. Because of this complexity wide range of drug formulary and drug delivery strategies has been developed in animals for health care. Route of drug administration varies from oral administration, parenteral administration to local application on skin and mucus membrane. Similarly forms of the drugs varies from liquids, semisolids to solids for oral administration; from clear solution, suspension, emulsion to powder for parenteral administration; and from powder, cream, paste, suspension, ointment, solutions to emulsifiable concentrates for local application. Oral Administration of Drugs All three forms of drugs viz. liquids (solution, emulsion, suspension), semisolids (paste), and solids

Liver is one of the largest and most sensitive organ in the body performing important role in digestion and metabolism; regulation of nutrient; and production of proteins, enzymes, hormones, clotting and immunological factors. Liver also plays significant role in detoxification. Liver is affected in both primary and secondary liver diseases. Clinical signs of the hepatic dysfunction appears only after a large portion of the liver (about 75%) is inactive because liver has a large reserve of function. Therefore, a systematic clinico-pathological examination of the liver becomes mandatory to identify liver abnormalities. Clinical Signs of The Liver and Biliary Disease Jaundice (pre hepatic, hepatic, post hepatic or extra hepatic), nervous signs (hyperexcitability, convulsions, coma, weakness, muscle tremors, dullness, compulsive walking head pressing, mania),

Besides physical examination, there are many diagnostic techniques for making a specific diagnosis of respiratory diseases. The specialized techniques are used by the specialists. These specialized examination techniques include collection of nasal and brochoalveolar samples either using nasopharyngeal swab or flexible fiber endoscopy and their laboratory examination; pleuroscopy; thoracocentesis; thoracic radiography; and thoracic sonography. Collection of Respiratory Tract Discharges/Fluid The respiratory tract discharges (nasal, bronchoalveolar fluid) can be collected using nasopharyngeal swabs and flexible fiber optic endoscope or flexible tube. Nasopharyngeal swab collection Nasopharyngeal swabs have been used to identify PI3 and IBR infections. Pasteurella isolates may be commensals. Bronchoalveolar samples are more exact than nasopharyngeal swabs in identifying

Peritoneal Fluid Peritoneal fluid (PTF) is an ultra-filtrate of plasma. The amount of the fluid and its constituents depends on oncotic and hydrostatic pressures, vascular permeability, mesothelial lining integrity, and lymphatic drainage. In healthy animals, the amount of peritoneal fluid is negligible making its aspiration difficult. However, in large animals, a small volume (up to 5ml) can be aspirated. Volumes of 10ml or above may indicate a pathological process in the abdominal cavity, unless the animal is in late pregnancy. Indications for collection and analysis The collection and analysis of peritoneal fluid is important in the diagnosis of diseases of the peritoneum and the abdominal segment of alimentary tract .Increased accumulation of peritoneal fluid may be evident in congestive heart failure, peritonitis, nephrotic syndrome,

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,

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.

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

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.

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

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

Common risks include patient handling, repetitive movements, prolonged standing, awkward postures, mental overload and poorly designed workstations. The chapter considers physical ergonomics, workflow design, cognitive support and stress management as complementary approaches to improving healthcare delivery. Safe patient-transfer techniques, adjustable furniture, accessible equipment and logically arranged clinical spaces are discussed. By reducing fatigue and occupational injury, ergonomic interventions can improve staff health, job satisfaction, patient safety, clinical accuracy and organizational efficiency while decreasing absenteeism and employee turnover.

This chapter explores how ergonomic design influences learning, teaching and well-being in schools, colleges and universities. It examines classrooms, laboratories, libraries, study spaces and digital environments as integrated physical and cognitive systems. Appropriate furniture dimensions, adjustable seating, suitable desk heights, lighting, ventilation, acoustics and equipment placement can improve posture, concentration and participation. The chapter also considers anthropometric differences among learners of different ages and abilities. Technology must be incorporated without increasing visual fatigue, physical strain or cognitive overload. By combining human-centred spatial planning with flexible furniture and supportive environmental conditions, educational institutions can create safer, more inclusive and effective settings for both students and teachers.

Soil chemical properties determine the availability, retention and movement of nutrients and strongly influence plant growth under irrigated conditions. This chapter introduces the fundamental chemical characteristics of soils, with particular emphasis on exchangeable bases, cation exchange and anion exchange. Cation exchange capacity (CEC) is discussed as an important indicator of the soil's capacity to retain and exchange nutrient cations. The chapter explains the principles and reactions involved in cation exchange, cation selectivity and the determination and expression of CEC. Relationships between CEC, soil pH and particle size are also considered, together with the concept of base saturation. These properties are important for understanding nutrient availability and fertilizer management in different soil types. The chapter further introduces the mechanism of nutrient uptake by plant roots, linking soil chemical reactions with plant nutrition. Understanding these processes provides an essential basis for managing soil fertility, improving nutrient-use efficiency and maintaining productive irrigated soils.

Respiratory examination is essential for identifying abnormalities of the upper and lower respiratory tract and determining the location and severity of disease. This chapter describes systematic evaluation using observation, inspection, palpation, percussion and auscultation. Respiratory rate, effort, pattern, nasal discharge, coughing and abnormal respiratory sounds are important clinical findings. Examination of the thorax and lungs helps identify changes associated with respiratory disorders. Advanced diagnostic approaches and sampling techniques may further support diagnosis. The chapter provides practical guidance for evaluating respiratory function in veterinary patients and emphasizes systematic examination for differentiating respiratory disease from abnormalities originating in other body systems.

The musculoskeletal system provides structural support, protects organs and enables movement. Diseases involving muscles, bones, joints, ligaments and tendons commonly produce lameness, pain, weakness, reduced mobility and deformity. This chapter presents general and special examination techniques for evaluating musculoskeletal abnormalities. Assessment includes observation of posture and gait, palpation of muscles and joints, evaluation of swelling, pain and abnormal movement, and examination of limbs and feet. Additional diagnostic procedures may be used to localize lesions. The chapter provides practical guidance for systematic examination and emphasizes accurate identification of affected structures to support diagnosis and appropriate clinical management.

Udder examination is essential in dairy animals because mastitis directly affects animal health, milk quality and farm productivity. This chapter presents practical examination of the udder and teats, including inspection and palpation for abnormalities. Mastitis detection methods include the California Mastitis Test and other milk-based diagnostic procedures. Evaluation of milk characteristics, somatic cell changes and laboratory findings helps identify inflammatory and infectious processes. Appropriate sampling and interpretation support selection of effective treatment. The chapter also emphasizes the importance of early detection and systematic udder examination in maintaining milk quality, preventing production losses and improving overall dairy herd health.

Veterinarians may encounter disease outbreaks, sudden increases in illness or unexplained changes in herd production. This chapter presents practical approaches to investigating and controlling such outbreaks. Effective investigation requires systematic collection of clinical, epidemiological, management and environmental information. Identification of affected animals, temporal patterns, potential sources and routes of transmission helps establish possible causes. Appropriate diagnostic sampling and laboratory investigations support confirmation. Immediate control measures may include isolation, biosecurity, treatment, vaccination and environmental management depending on the suspected disease. The chapter emphasizes organized outbreak investigation, rapid decision-making and coordinated control measures to limit disease spread and reduce losses.

Environment in which crops are grown dictates their final yield. Of these environmental factors, climate and weather the uncontrolable factors, have maximum influence on crop productivity. Vagaries of weather subject a crop to different ecological situations from year to year leading to differential responses of crops to input resources. This situation limits the use of costly inputs for realizing optimum yield. While weather itself cannot modify, the hazardous weather can often be mitigated by agronomic management. Therefore, the primary requirement for initiating agronomic measures against weather hazards is foreknowledge of weather situation that is likely to develop in an area.
