Artificial intelligence is a computational science concerned with smart computer machines capable of performing tasks similar to the human intelligence. The term AI is widely used for the projects involved in the developing the intellectual processes of human intelligence such as reasoning ability, meaning discovery, generalization, learning from the past. AI technology mainly analyses the huge amount of data based on the set of instructions or commands known as algorithms to do a specific function or task. The mathematician Alan Turing with a simple question “Can machines think?” revolutionised the history. His paper “Computing Machinery and Intelligence” in 1950 and Turing test has favour the development of goal and the vision of AI.

The research in AI are mainly focussed on the following intelligence components namely:

1. Learning
2. Reasoning
3. Problem solving
4. Perception
5. Language use

Introduction

Impact assessment (IA) is defined as "a set of logical steps to be followed in the preparation of policy proposals. It is an essential tool to ensure that policies are crafted based on transparent, inclusive, and balanced procedures, define the various quality standards, and provide basic instructions to the impact assessment process" (European Commission).

Introduction

Hematology is the study of blood and its constituents. Blood is a specialized fluid connective tissue, which consists of plasma (55-70%) and the formed elements (30-45%) that flow all over the body in the vessels of the cardiovascular system. Plasma comprises water (90-92%), proteins (6-7%), enzymes, hormones, lipids, and organic & inorganic constituents. The three major classes of plasma proteins include albumin, globulin, and fibrinogen. The organic elements include non-protein nitrogen (NPN) compounds (like urea, uric acid, creatine, creatinine, amino acids, glutathione, and xanthine), glucose, neutral fats, phospholipids, cholesterol and others. The inorganic constituents include calcium, phosphorus, magnesium, potassium, sodium, chlorine, sulfur, iodine, iron, copper, cobalt, manganese, zinc, selenium, and molybdenum; they contribute about 1 percent of the plasma.

Blood performs various functions by its constituents. The constituents of the blood are highly dynamic, and they inter shift from their reference values very quickly in any adverse condition. This is why; studies of blood cells and complete blood count (CBC) are important for accessing general health, diagnosing various diseases, and providing prognostic information when coupled with a thorough physical examination. The blood examination is performed routinely to diagnose hematological diseases, including certain hereditary diseases of the blood, and to determine the body’s ability to respond to a hematological insult. The key parameters evaluated in the hemogram are ESR, PCV, Hb, TEC, MCV, MCHC, TLC, and DLC.

Introduction

Its fruits are attractive, delicious and highly nutritious. This is a temperate crop that is drought-resistant and salt-tolerant. largest Producer-Turkey. It is a rich source of protein and oil (40-45 %). Use it for tumer and ulcer treatment. highest antioxidant content (carotenoids) Laetrile, a purported alternative treatment for cancer, is extracted from apricot seeds. Moor Park one of the best apricots for outdoor cultivation in a small garden. It is very rich in Vitamin-A and also contains more carbohydrates, proteins, and phosphorus than the majority of common fruits. They are mostly used as dessert, and because of their perishable nature, they can be canned, frozen and dried. The fruits are also processed into jam, nectar and squash. The kernels, which are either sweet or bitter depending upon the variety, are a valuable by-product. Sweet kernels are used in confectionary, while bitter kernels are used for oil extraction and raising rootstocks. It is very rich in Vitamin-A: 3600 IU and Thiamine: 217 mg/100 g.

Introduction

The Arecanut palm is cultivated primarily for its kernel obtained from the fruit, which is chewed when it is tender, ripe or processed. Despite being native to the Malayan Archipelago, the Philippines, and other East Indian Islands.Only in India is it under scientific cultivation. India is the world’s largest producer of arecanut, contributing nearly 74 % of world production. India is the world’s largest consumer of arecanut (accounting to 89 % of world production). Other uses for arecanut other than chewing are negligible. Its export prospects are also very limited. Therefore, the present policy is not to expand the area under arecanut but to adopt intensive cultivation and take up replanting of the aged and unproductive gardens. Inter and mixed cropping in arecanut gardens is advocated to augment the income from the existing arecanut groves. Alkaloids present in arecanut, Arecoline is the main and physiologically most active alkaloid present to an extent of 0.07 to 0.1 per cent.

Introduction

It is a subtropical, evergreen fruit tree. Its trees can be short-spreading and fairly bushy or grow erect to a height of 20 m. Tree demand for this fruit has been increasing over the past few years in many countries. It has become an important fruit in international trade. Mexico, Colombia, Dominic Rep, Peru, Indonesia, South America and South Africa are the major producers of avocado. In India, it is grown as a backyard tree and is found in small pockets on the hill slopes of Tamil Nadu, Kerala, Karnataka and Maharashtra. Composition and uses: One of the most nutritious fruits, rich in fat, protein, and minerals and low in carbohydrates, is the avocado. It can be safely eaten by diabetics. Fruit is used as a dessert in salads, ice creams, and milk shakes.

Immature fruits may have a bitter flavour that may be reduced on ripening; the peel of avocado has 3 antifungal compounds. Its energy value is twice as much as banana fruit. Rich in fat 26.4% and low sugar 1% content and rich in K, Fe, Vitamin B, As the sugar content is low, it can be recommended as a high-energy food for diabetics. Fruit is a rich source of oil, ranging from 5–20% used for the cosmetics industry.

Bael, one of the oldest fruits cultivated in India, has a mythological significance, viz., leaves used for the worship of Lord Shiva. The flower contains numerous stamens, which is hypogenous. The seed is monoembryonic. It is a deciduous tree with trifoliate leaves. Aegle is a monotypic genus with deciduous foliage. Bael has dimorphic twigs.

Introduction

The fruit is recognized as the fourth most important global food commodity.

It is used as a staple fruit in most African countries and is used as ripe (table)

or raw fruit (cooking). This fruit is available throughout the year. All the plant parts are being used. Banana is a tropical, herbaceous, monocotyledonous and monocarpic fruit crop.

Introduction

The West Indian Cherry is a very important fruit because of its high ascorbic acid content (10-33g/kg edible pulp). It is widely distributed throughout tropical America, Africa and the West Indies. It is also called Acerola, Cereza in Puerto Rico, Barbados cherry in Florida and Texas. Leading producer’s countries of cherry are Turkey, USA, Chile, Uzbekistan and Iran. The plant is ornamental and when laden with clusters of its crimson fruits, presents a very attractive appearance. It is a medium-sized shrub and can serve as an ornamental tree on account of its fruits, flowers, foliage and drooping branches. Eating one or two fruits every morning will meet the daily requirement of vitamin C. This is a small shrub or small-sized tree growing up to 8.0 m in height and doing well in a tropical climate. The flowering seasons are May and November.

Basic knowledge of statistics is important to understand animal breeding analysis. In this chapter, the hypothesis testing, principles of experimental design, types of data and probability distribution are described with examples using appropriate software.

The betelvine is a perennial dioecious climber and is believed to have originated in Central and Eastern Malaysia. It is mainly cultivated in South East Asian countries, viz., India, Bangladesh, Sri Lanka, Malaysia, Thailand, Philippines, etc. It is one of the important commercial crops grown mostly by small and marginal farmers in the states of Assam, West Bengal, Bihar, Andhra Pradesh, Karnataka, Tamil Nadu, Maharashtra, Madhya Pradesh, Kerala, Uttar Pradesh and Orissa with an estimated area of 53,539 ha (Ray, 2008). Annual production is worth Rs. 9000 million and estimated that about 20 million people earn their livelihood directly or indirectly partly or fully from production, processing, handling, transportation and marketing of betel leaves in India. Betel leaves worth 30-40 million rupees are exported to countries like Bahrain, Canada, Great Britain, Nepal, Pakistan, Saudi Arabia, and many other European countries.

Introduction

Breadfruit has long been an important staple crop and a primary component of traditional agroforestry systems in the Pacific, where numerous varieties are grown. Breadfruit was first domesticated in the western Pacific and has been spread by humans throughout the region over the past 3,000–4,000 years. From

Melanesia to Micronesia to Polynesia, many islanders grow and use breadfruit as part of their daily diet. Breadfruit has a significant and often unappreciated legacy in Hawai. It is one of the canoe plants brought from the society Islands centuries ago, and the variety they brought, known simply as ‘Ulu (same as the

Hawaii a word for breadfruit), was widely grown throughout the archipelago.

Introduction

The cardiovascular system is comprised of the heart and blood vessels (arteries, capillaries, and veins). The heart pumps blood to blood vessels which allow blood to flow throughout the body. Both heart and blood vessels are work together to keep the blood circulating, ensuring the interchange of O₂, CO₂, electrolytes, and nutrients between the blood and the tissue fluids & cells, and removing waste products from the body via the excretory system.

The purpose of the study of the cardiovascular system is aimed at understand the pathophysiology of the heart and vascular system. A physical examination, arterial blood pressure, and electrocardiography are routinely employed to examine the cardiovascular system. The physical examination of the heart includes palpation, percussion, and auscultation.

Introduction

A case study involves a thorough examination of an individual, group, or event, delving into nearly every facet of their life and history to identify patterns and causes of behaviour. This investigative approach finds application across diverse fields such as psychology, medicine, education, anthropology, political science, and social work. The primary objective of a case study is to acquire comprehensive knowledge about a specific individual or group, enabling the generalization of information to a broader audience. However, it is worth noting that case studies often exhibit a high degree of subjectivity, making it challenging at times to extrapolate results to a larger population.

Introduction

Cashew is native to South Eastern Brazil, from where it was introduced to the Malabar coast of India in the sixteenth century to cover bare hills and for soil conservation. It gained commercial importance in 1920. African countries produce large quantities of cashew nuts, but they are not processed into consumable products because of difficulties in organizing the native labour. India imports raw cashew nuts which are processed and converted into cashew kernels and cashew shell liquid and re-exported to countries like the USA, Canada, the United Kingdom, Australia and Russia. The cashew kernel of India is of the highest quality in the world. India is the largest producer and exporter of cashews in the world. India stands first in area and production in the world. Indian cashew export: 63 per cent of global cashew trade. The national average is 835 kg per ha (i.e., around 5.50 kg per tree) and this is far less than the achievable level of 2000 kg per ha (i.e., around 12.50 kg per tree). Maharashtra state is having the highest productivity of about 1337 kg per ha (mainly due to adoption of drip irrigation and mulching techniques), while productivity in West Bengal has come down (1140 kg/ha), mainly because of old plantations. Due to its nutritive value and commerce, it is designated as “zero cholesterol nut or white gold”. The cashew nut is a unique combination of fat (47 %), protein (21 %), carbohydrates (22 %) and vitamins (10 %). India contributes about 65 % of the world’s exports. The USA is the largest importer of cashew kernels.

Agriculture and Food Security

Food security refers to a situation when people gain physical and access to enough food to meet the dietary requirements for a healthy life for all times. A household can have food security when all the members lead a hunger free life. It is estimated that nearly 800 million people in the world go to bed hungry every night. Food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life (World Food Summit, 1996). This definition gives rise to four dimensions of food security: availability of food, accessibility (economically and physically), utilization (the way it is used and assimilated by the human body) and stability of these three dimensions.

Introduction

Cherries occupy an important position among temperate fruits all over the world. Cultivated cherries are divided into two main groups, i.e., sweet cherries (Prunus avium) and sour cherries (P. cerasus). Cherries are rich in protein, sugar, potassium, calcium, iron and zinc. Sweet cherries are believed to have originated in an area between the Black and Caspian Seas in Southern Europe. The earliest records indicate that it was first domesticated in Greece around 300 BC. It spread to Italy from Greece where it was established as a fruit crop by 37 BC. Early setter’s brought seeds to North America and parts of South America. In India, it was introduced by British setter’s in Kashmir, Kullu and Shimla hills during the pre-independence era. World leading breeding of cherry: John Innes Horticultural Institution, Merton. A putative ancestor of cultivated sweet cherries: Anthocynins (antioxidants) are the red pigment found in cherries.

Introduction

The chestnut is similar to the acorn of oak. Chestnut trees have been growing in the temperate climate of the world for more than 4,000 years for beauty, fuel and shelter. The sweet chestnut is some nutritious low-fat food rich in vitamin B. Freshly harvested nuts contain about 50 per cent moisture, 40-42 per cent carbohydrates, 2.9 per cent proteins and about 1.5 per cent fat. In addition to providing a good food source for humans, chestnuts also provide food for a number of wild life species. Its wood is durable and used for timber and furniture work. Chestnuts and chinquapins are exceptions to all other nut trees in that they contain little oil and are high in carbohydrates, particularly in starch.

Introduction

An herb known as priyal is a drug of the Ayurveda and the Unani system of medicine. It is known to have tonic, cardiotonic, and astringent properties and is also used in the treatment of skin diseases. It is commonly known as Chironji. It is a commercially useful tropical plant. The Chironji tree is a medium-sized evergreen deciduous tree, growing 50 ft tall. It bears fruits, each containing a single seed, which is a popular edible nut, known as chironji. It is common in India, mostly in eroded land. This tree is distributed in the states of Madhya Pradesh, Bihar, Orissa, Andhra Pradesh, Chhattisgarh, Jharkhand, Gujarat, Rajasthan, Maharashtra and also commonly found in Uttar Pradesh.

Introduction

Citrus is the leading tree fruit crop in the world. In India, citrus ranks second in area, sharing 12.8% of the total area under fruit crops with a 9.6% share in production. In the citrus group, mandarins are the most important, occupying 50% of the total area under citrus, followed by sweet oranges and limes. “Limolin”: the glycoside which is responsible for the bitter taste of citrus fruit juice.

Energy is a critical component of the economic infrastructure, as it is the primary input required to support economic growth. Economic development and energy use have a close relationship. The higher a country’s per capita energy usage, the more developed it is and vice versa. Human civilization is dependent on several energy sources.

Introduction

The Greek names Theos and Broma mean “Gods” and “Food,” respectively. Cocoa consumption is in temperate countries. Cocoa is a beverage crop introduced for cultivation in India in the early 1965. The cocoa plant is a perennial dicotyledonous which has been under cultivation since pre-historic times. shade-loving and evergreen trees. It is native to the Amazon valley of South America and is now cultivated largely in Cote d’Ivoire, Ghana, Nigeria, Indonesia, Peru, Sierra Leon Cameroon, Equator, West Indies and Malaysia. In India, cocoa is mainly grown in Andhra Pradesh, Tamil Nadu, Kerala, Karnataka and. It is a rich source of fat (37%) and protein (7%). It also produces theobromin. Cocoa is used in manufacturing chocolate, cocoa powder, cocoa butter and other nutritious foods.

Introduction

Coffee is the second important beverage, ranking second among traded commodities. Its dried beans are roasted, ground, and brewed to make a stimulating and refreshing beverage. Arabica coffee originated in Ethiopia, from a place called Caffa. The word “coffee” is derived from a place called “Caffa.” Here it occurs naturally in the forest between 1,400 to 1,800 feet of elevation. Nearly 80 percent of the world’s coffee is produced by Coffea Arabica. Robusta coffee is thought to have originated in Central Africa (Congo and Zaire). Arabica coffee was introduced in 1670 by Muslim pilgrim Baba Budan. He brought seven seeds from Yemen and cultivated them in Chikmagalur, Karnataka. The original seeds he brought were probably Mokka seeds. Robusta coffee was introduced from the Indochina region at the close of the 19^th century for planting in the states of lower elevations. World: Brazil, Vietnam, Colombia, Indonesia, India, Ethiopia, Peru, Mexico, Guatemala and Honduras. It is also growing in India in Karnataka, Kerala, Tamil Nadu, Andhra Pradesh and Orissa.

It is known that the phenotype of an individual is a combination of genotype and environment. Animal breeding analysis is mainly done to partition the genetic part from the environmental part so as to assess the actual genetic worth of the animal. In this process correction for the known environmental part is integral to any animal breeding analysis. In this chapter, a list of common factors affecting important economic traits are described. The analytical part for these effects will be explained in later chapters.

Correction or standardization of data is very important in any animal breeding analysis. Unless the candidates under selection are placed on a common platform, various factors affecting the trait will lead to bias in assessing the performance of the individual with respect to a particular trait. For eg. a lamb born during a favorable season, a lactating cow in its third parity, first lactation yield of a cow with longer age at first calving.

Correlations and regression are important components of animal breeding analysis. The genetic correlation is an important genetic parameter that is useful in the planning of breeding programs involving multiple traits. In this chapter, the basic concepts of correlation and regression including method of estimation, assumptions and test of significance are presented. An example using SPSS software is also given at the end for better understanding.

Introduction

It is found growing wild in the sub-tropical and tropical parts of India. The edible part of annona is the areoles. It has about 120 species, five of them having pomological significance, and four of the five species are important in commerce. Custard apples are cultivated mainly in Maharashtra, Madhya Pradesh, Gujarat, Karnataka, Andhra Pradesh, Uttar Pradesh, Bihar, Assam, and Orissa.

Introduction

The flesh contains 60–65 percent sugar, 2 percent protein, 2.5 per cent fiber, 0.4 per cent fat and 2 per cent mineral matter. Date palm contains 75-80% carbohydrates in the form of invert sugar. It is a good source of easily assimilable iron (7.3 mg/100g) and is hence prescribed to anaemic patients along with honey. It fed on running water and its head on the fire of the sky.

Pomology: Pomology is a branch of horticulture that deals with the cultivation of fruit crops. When given a liberal and flexible translation, the word “pomology” means the science of fruit. The term is derived from the Latin word pomum, which means “Fruit” and the Greek term logy, which means “Science.

Fruit

“A true botanical fruit is defined as a mature or ripened ovary with or without accessory organs.” Classifcation refers to the grouping of individuals with similar identities, related in genetic make up, evolution or climatic requirements. The major units of classification are order, family, genus, sub family, species, variety/cultivars and clone or strain. All fruit crops bear flower and seed (spermatophyte) and belongs to class Angiosperm except in (Pinus gerardiana) of gymnosperm.

Most of the fruits are covered under the dicotyledonous families of Angiosperm except banana, pineapple, date and coconut which belong to monocotyledonous families e.g. Musaceae, Bromeliaceae and Arecaceae (Palmae) respectively. The families of economically important fruits include Rosaceae (all pome, stone fruits and strawberry), Rutaceae (citrus fruits, bael and woodapple), Musaceae (banana and plantain), Vitaceae (grapes and Anacardiaceae (Mango, cashew and pistachio nut, hog plum) etc.

Introduction

The digestive system and its auxiliary organs main functions include digestion and the absorption of nutrients required for cell metabolic processes. Digestion is the mechanical and chemical or enzymatic breakdown of large nutritional macromolecules into simpler molecules that cells can absorb. It takes place in the aqueous milieu of the digestive system and is secreted by the salivary glands, stomach and mucosal glands, pancreas, and liver.

Digestive enzymes are secreted almost throughout the digestive tract. Salivary enzymes such as lingual lipase and α-amylase initiate the breakdown of fat and carbohydrates in the mouths of young animals (e.g., calves) and omnivores (e.g., rats, pigs, and humans).The optimum pH for oral digestion is 6.7 (6.2-7.6).

The gastric juice contains pepsinogen, HCI, and intrinsic factors. The pepsinogen enzyme is secreted by the stomach’s chief cell. Pepsinogen is converted to pepsin at acidic pH ranges of 2.0 to 3.5 and initiates the digestion of proteins in the stomach of monogastric animals. Also, the stomach’s parietal cells secrete HCI and intrinsic factors. Cyanocobalamin, is a synthetic form of vitamin B₁₂ requires an intrinsic factor in ruminants to be absorbed. The abomasum of young ruminants secretes proteolytic enzymes such as rennin or chymosin. Rennin acts on milk at a pH of 6.5.

Introduction

Pitaya also known as Dragon Fruit is a superfruit indigenous to central and South America that is grown all over the world. It has a faint, sweet taste much like an earthy watermelon. It’s a fast growing crop and the plant as can have produced for more than seven to eight years. The fruit of this plant having red skin covered with large scale and white or pinkflesh contains some black seeds. It can be used in jams, ice creams, jelly production, fruit juice, and wine. This fruit is famous in Thailand, Vietnam, Israel and Sri Lanka. This fruit cultivation is excellent in regions where less rainfall is expected. This fruit plant is treated as an ornamental plant as well as a fruit producing plant. Dragon fruit contains 73.9 kcal, 1 g protein, 0 g fat, 0.5 g fiber, 23 g carbohydrates, 23 g sugar, calcium 30 mg. 10.9 mg sodium and 1.79 mg vitamin C. Dragon fruit is consumed as a fresh fruit or can be used in jams, ice cream, jelly production, fruit juice and wine. This fruit is also used in face packs.

Introduction

The durian is an important fruit in several parts of the tropics and is the famous fruit of the far East, where it is widely cultivated throughout Malaysia. It is indigenous to Malaysia, i.e., South East Asia, and is distributed in Malaysia, Indonesia, Philippines, Thailand, Singapore, Kampuchia, Myanmar, India, and Sri Lanka. The term durio is the Malaysian word duri-thorn, and zibethinus is the Italian word for “zibetho,” meaning “strong-smelling. Thus, this is a fruit characterised by a greenish, hard, thick rind on the outside and a yellowish, sweet flesh with a strong odour. The fruits are nothing but seeds covered with a cotton-like fibre.

Introduction

Everyone is familiar with the term start-up or entrepreneurship which refers to a process by which individuals start and manage their businesses and industrial enterprises. Entrepreneurs are people who take risks and invest their capital in businesses and industrial enterprises. Entrepreneurial in terms of personal development in terms of self-determination create take risks Therefore, anyone who exhibits the characteristics of self-development, creativity, personal decision-making, and risk-taking can be called a person with entrepreneurial characteristics. When these characteristics are exhibited by someone who is running a business, they can be called an entrepreneur. Entrepreneurship is the ability and willingness to develop, organize and manage a business enterprise, with all its uncertainties, in order to make a profit. The most prominent example of entrepreneurship is starting a new business. In economics, business activities involving land, labor, natural resources, and capital can generate profits.

Introduction

Endocrinology is the study of the endocrine system, which includes the glands and their secretions known as hormones. Hormones are essential for animal behaviour, growth and development, metabolism, lactation, reproduction, excretion, and reabsorption of inorganic ions. Therefore, if a certain hormone concentration in blood or another body fluid is detected, it provides the pathophysiology of the representative endocrine gland.

Endocrine glands, the cells or tissues they govern, and the secretory substances (hormones) they produce are investigated using a number of methodologies. They are as follows:

1. Surgical methods (e.g., hypophysectomy, gonadectomy, etc).
2. Chemical ablation or impairment (e.g., alloxan or streptozotocin agents that selectively destroy the insulin-secreting beta-cell, etc).
3. Hormone replacement therapy (e.g., estrogen during menopause to reduce the risk of bone fracture related to osteoporosis, etc).
4. Immunological neutralization of hormone activity (e.g., contraception both male and female, injection of antibodies against NGF resulting in failure of sympathetic nervous system development, etc).
5. Tissue extraction and purification (e.g., progestin is a synthetic hormone that mimics progesterone, etc.).
6. Histological-cytological studies (e.g., employment of a battery of histological stains to characterize each pituitary cell, etc).
7. Bioassays (e.g., oxytocin-induced contraction of rat uterine myometrial tissue strips, etc).

Definitions of Energy

Energy is a key topic in science and technology, as well as in society in general. In terms of energy, a typical definition found in popular literature as well as textbooks is “energy is the ability to do work” or, much more precisely, “energy is the capacity of a system to do work” [Atkins 1990].

Energy is described as the ability to generate change or carry out work, and that work can be separated into numerous easily identifiable tasks: Energy produces light, heat, motion, sound, growth, power and technology etc.

Energy in Agricultural Context (FAO)

Agriculture’s fundamental and foremost function is to produce food and other primary products, so contributing to food and nutritional security. Sustainable Agriculture and Rural Development (SARD) attempts to promote ecologically non-degrading, technically suitable, commercially successful, and socially acceptable development in the agriculture, fishery and forestry sectors. Achieving food security necessitates policies that promote social, cultural, political, and economic stability. Integrating agriculture’s economic, social, and environmental roles can help to attain these objectives.

Agriculture may provide a variety of non-food commodities and services. This can include its application as a viable, long-term source of energy. According to the FAO, agricultural activities and related land use directly contribute to non-agricultural functions such as social, environmental, economic and cultural products and services. They can have major advantages or disadvantages. Research reveals that, in addition to food security, agriculture contributes significantly to attaining sustainability at the local, national and global levels in rural development, energy and the environment. The efficient operation of the market encourages the identification and strengthening of these many functions, as well as the development of new techniques and technologies. Plant and crop-based resources are utilised as raw materials in a wide range of industrial goods, including wood for paper and board production, starches for adhesives, and vegetable oils for paints and resins.

Entrepreneurship opportunities in veterinary sciences have expanded significantly with the integration of technology. The convergence of veterinary expertise and innovative technological solutions has opened up new avenues for entrepreneurs to create impactful businesses in the field. This field offers a wide range of opportunities for persons passionate about animal health and welfare. In the recent years, the demand for high-quality veterinary services and products has increased tremendously, creating an enriching environment for aspiring entrepreneurs. There are various avenues available in the veterinary industry for individuals thinking about establishing their own businesses.

Introduction

Climate change induces significant and long-lasting shifts in the statistical distribution of weather patterns over periods ranging from decades to million years. It is believed to be the cause of long-term temperature changes, changes in rainfall patterns and volume, prolonged summer seasons, increasing sea levels, and increased frequency and intensity of floods, droughts, and heat waves, etc.

Animals are intimately and inseparately associated with their physiological and chemical environments from conception until death. As a result, climate change has an impact on animals both directly and indirectly. Since, animals have had to alter their behavioural and physiological mechanisms in order to maintain homeostasis.

Climate change has emerged as a serious threat to the livestock industry. It reduces animal productivity by lowering growth, milk yield, meat production, egg production, wool production, reproductive performance, and health. About 20 to 30 percent of plant and animal species would likely be at risk of extinction with an increase of 1.5 to 2.5°C, which will result in severe consequences for food and nutritional security in developing countries. This is why; measurements of meteorological variables are needed for effective scientific management of livestock and poultry to cope with the negative impacts of climate change while enhancing growth and productivity.

Estimation of variance is primary for any breeding program as all the genetic parameters are dependent on these estimates. The properties of an estimate, their assumptions, type of data, availability of data, and computational requirement make it important to understand the method of estimation of variance components so as to make a wise choice that would suit the breeder’s requirement. This chapter explains the methods of estimation of variance with merits and demerits of each and the reader could use these as a guide to choose the right method of estimation.

The genetic parameters are the basis for any animal breeding program and the important parameters such as heritability, repeatability and genetic correlation are ratios of (co)variances and their reliability depends on the accurate estimation of variance components. Estimates of variance components are used extensively in animal breeding.

Introduction

The kidneys play a vital role in maintaining water and electrolyte balance (such as chloride, potassium, calcium, hydrogen, magnesium, and phosphate ions). It also regulates the acid-base balance of the blood, arterial blood pressure, and osmotic pressure of the nd water-soluble waste products, which are removed from the bloodstream by the kidneys and excreted as urine. Normally, the kidneys receive about 22% of the cardiac output. According to Arthur Cushny (1866-1926), there are three steps involved in urine formation in the nephrons: glomerular filtration, tubular reabsorption, and tubular secretion. When the kidneys are injured, their regulatory activities are disrupted, resulting in a change in the quality and quantity of urine. Urine is composed of the following components:

This is the reason why a urine analysis is a common test to evaluate the pathophysiology of the urinary system in general and the kidneys in particular, as well as to aid in the differential diagnosis of certain diseases.

Services for CSA

Under the CSA projects and programmes, the services like supply of inputs and technology transfer through extension services are provided to the farmers. The inputs like seeds of crops are provided by the input dealers at the subsidized rate and seedlings of fruits and vegetables are provided by both private and government agencies to grow under general cultivation and poly-house cultivation technology. Similarly other services like soil testing facilities, issue of soil health cards, construction of micro-irrigation projects and rain harvesting structures are made available to farmers. Under insurance scheme, loanee farmers are supported to pay premium dues for availing crop insurance facilities. Other services like trainings at various levels, demonstrations, exposure visits, exhibitions, kisan melas, field days, monitoring and evaluation of all these activities under these programmes are provided to the farmers with collaboration of extension officers.
