Visiting the zoo should be understood in terms of conservation by all and it is to be remembered that the zoo is a captive wild animal place wherein the public and particularly the children have ample opportunities to see the various species of wild fauna which includes not only the native species of wild mammals, reptiles, aves, amphibians, butterflies etc. but the exotic speciess of wild animals also in general.

The ability to inject a drug into a free ranging animal using a remote injection system is a main stay of zoo and wild life medicine and the accepted and routine procedures of today for anesthetizing free ranging, dangerous, or hyper excitable animals are to be well understood for the proper preventive medical procedures, medical treatment, surgery, or scientific study. However, all these were earlier existing only as a dream, until remote injection-based gadgets like darts, blow pipes and distant drug-delivery gadgets like pistol and rifle were duly developed, in conjunction with safer injectable anesthetics.

Hard tongue due to fibrous tissue proliferation (termed as wooden tongue) is a characteristic feature.

Swab and smear from abscess and tissue samples including tongue and lymphnodes.

The ancient wisdom of the Indians about the value of pulses in human nutrition is perhaps, responsible to an extent for the widespread vegetarianism in our country. The staple pulse component in combination with cereals in our diet emanates from this recognition, Modern nutritionists also substantiate that this combination is superior to either pulse or cereal alone.

Agriculture is the mainstay of the economy in different developing countries and it is not only nourishing the population, but also contributing a major share in country’s gross domestic product (GDP). During the second half of the twentieth century and after, modern agriculture encouraged intensive cropping with high cost and consumption of fossil-fuel based energy. Yield enhancement was achieved by adoption of modern technologies, but that was at the cost of ecological unbalance.

Agriculture is an important factor for human civilization as it not only provides food, feed for the livestock, fibre, fuel and industrial raw material but also supports the livelihood of a wide range of world population. Besides, it shows its prominent presence in the economy of the developing countries. Being a developing country, agriculture is the largest sector in India where about 54% of the population is engaged. The growth of agriculture in India during last seven and half decades (after independence) is quite remarkable in terms of sufficient food-grains production as well as in achieving self-sufficiency in food production. The task to achieve it was not so easy.

Worldwide, agriculture contributes a lot for mankind by providing food and feed for human beings and livestock, respectively. The countries where agriculture plays a vital role, it has enough importance in the economy of the country as well as gross domestic product (GDP).

In the current situation, crop intensification is of topmost importance to increase agricultural production from ever-limiting and degrading resources. In this regard, the potential of agroforestry can be thought that offers ample opportunity to enhance farm output with multifaceted benefits (Xu et al., 2019). Forests are known to maintain ecological balance in many ways with greater ecosystem services; hence, the advantages of forestry can be included in agroecosystem in the form of agroforestry which enables yield of forest products and crops together

Enhancement of population is a global issue and the expected world population will be 9.7 billion in 2050 (UN, 2019). Under the situation, achievement of food and nutritional security is a major target with reduction of GHGs to the atmosphere and mitigation of ill effects of climate change. Modern agriculture is responsible for emission of GHGs in many ways and one of them is production of synthetic N fertilizer. There is no doubt about the fact that chemical N fertilizers enhance crop yield but it is at the cost of atmospheric equilibrium and agricultural sustainability cannot be achieved by this practice (Bedoussac et al. 2015; Layek et al., 2018).

Genetic purity is the vital determinant in continuing the genetic integrity in seed from generation to generation. This is the basis of variety purity maintenance. The genetic purity depends upon the purity of the seeds planted. The genetic purity of the seeds planted must exceed or equal to the final product purity standards required as the purity generally decreases with subsequent generations of propagation. The improved varieties loose their identity and healthiness unless properly maintained. Maintenance selection can prevent the seed quality deterioration.

Fungi are one of the major causes of crop damage which affect crop yield, quality and revenue. Therefore to control these fungal diseases, fungicidal crop protection products are used at different stages of crop growth. Many of our current fungicides produce excellent results with respect to efficacy, crop quality, food safety, and improved cost/profit ratios of agricultural production.

Actino-IronOG (Streptomyces lydicus WYEC)

Biological soil and seed treatment for Fusarium, Rhizoctonia, Pythium, and Phytophthora with added iron.

Tree canopy management affects fruit yield and quality by affecting light interception. The canopy geometry should be managed in such a way that it intercepts maximum light. For high density planting system a shallow (thin) canopy 1.5-2.0 m in depth is needed to achieve the maximum efficiency for trapping sun energy through foliage and channelizing metabolites for quality fruit production with good return.

The guava (Psidium guajava L.) also known as ‘the apple of tropics’ belongs to family Myrtaceae (Hayes, 1974) originated from Tropical South America stretching from Mexico to Peru and introduced in India by Portuguese during 17th century (Bose and Mitra, 2001). Guava is an evergreen fruit in nature, well adopted to a wide range of soil and agro-climates and acclaimed as ‘super fruit, due to high nutraceutical properties and in reach of poor people it has great demand.

Women account for 43% of the agricultural labor force in developing countries (FAO, 2011) and produce 50% of the global food production (FAO, 2011). Regional statistics reveal that in Latin America about, 20 percent, in Asia, about 30 to 60 percent, and in Sub-Saharan Africa, 50 to 75 percent of the agricultural labour force is supplied by women (FAO, 2013). Moreover, they invest 10 times more than their male counterpart in the family well being especially education and nutrition of children (Maertens and Verhofstadt, 2013). Despite being the primary contributors for the world food production, their roles are highly underestimated. Considerable gender bias exists in the agricultural sector, both in terms of quantities of assets, agricultural inputs and resources that women
control (Deere et al., 2013). Failure to recognize the roles, differences and inequities [between men and women] poses a serious threat to the effectiveness of the agricultural development agenda

Systematic Sampling (Meaning and Concept)

In this chapter, we are going to discuss the systematic random sampling technique. This is a random / probability / quantitative sampling method. In our previous chapter, we discussed the stratified random sampling technique. We have said that this technique is used when the population is heterogeneous and needs to be stratified into homogeneous groups. We have also discussed steps to be followed when using stratified random sampling as well as the strengths and limitations of stratified random sampling. Systematic sampling is a commonly employed technique if a complete and up-to-date list of the sampling units is available. The procedure involves choosing the very first object arbitrarily and the remaining members of the sample will be selected naturally according to any pre-decided sequence containing regular spacing of units. In this method, units of the population are numerically, geographically, and alphabetically arranged either in ascending or descending order (generally ascending order is preferred). When the ordering of the elements is related to the characteristic of interest,

Multistage Sampling

Multistage sampling is a form of random sampling where samples are selected in a sequence of stages. Where each sample is drawn from the exclusive previously selected samples. This sampling is not done once but at multiple stages. It differs from cluster sampling in the sense that cluster uses all the subjects within a cluster whereas multistage selects a sample from within the selected group. Groups are randomly chosen from a population; subgroups from these groups are randomly chosen and then randomly chosen to be surveyed.

This is an extension of cluster sampling, which is carried out in multiple stages say two, three or four stages. In the first stage, the universe is divided into some clusters from which certain clusters are selected at random at the first stage samples. In the second stage, the selected first stage samples are again subdivided into some clusters from which again certain clusters are selected at random as the second stage samples. In the third stage, the selected second stage samples are again subdivided into some clusters from which certain clusters are again selected at random as the third stage samples.

Introduction

In some practical field situations, the results are described by some percentages or proportions. In agricultural field conditions, if any disease prevalence is to find then in the form of percentage or proportion, we can say how much disease rate is present i.e., 10 % or may be any other. So, in those situations, we need to describe our results in proportions. Similarly, in many fields such as medical sciences, social sciences and other allied sciences this type of results in proportions we need to describe.

2.1 Manufacturing Process of Sugar

There are a number of steps in producing raw sugar from cane

1. Sugarcane receiving and unloading (receive the cane at the factory and unload it from the transport vehicles)
2. Sugarcane preparation (cutting and shredding cane to prepare it for juice extraction)
3. Extraction of Sugarcane Juice (two technologies are in common use; milling or diffusion)
4. Juice clarification (remove suspended solids from

The speed with which changes in the eye can take place is challenging. Ophthalmic problems do not lend themselves to casual examination or ‘trial and error’ therapy. Therefore, to perform safe cataract surgery with good quality outcome, uniform minimum standard of diagnostic and clinical practice needed to be in place.

Although cataract can be diagnosed by routine gross examination ofthe affected dog even then it is mandatary to develop a routine ophthalmic examinations in a consistent and organized manner to make a confirmatory diagnosis and plan the surgical technique for a favourable prognosis. A sequential examination starting right from history up to electroretinography may be performed as under:

History » Gross Examination » Menace response test » Obstacle course test » dazzle or photic blink reflex » Light induced pupillary reflexes (direct/ consensual) » Corneal reflex test »Schirmer’s tear test

Maintaining the required type of information in the form of records is primary for any type of animal breeding analysis and this chapter explains the importance of records and ways to maintain them in the form of registers or computer databases. The formats for different types of registers to be maintained are also given as a template in appendix. Any breeding plan is formulated to improve the economic traits depending on the utility of species reared and the chapter lists important economic traits of livestock and poultry with definitions and formulae, where ever required.

Basic record maintenance is a must for any animal breeding program. Every farm or breeding program is expected to maintain records in the form of registers or computerized databases. The goal of animal breeding is to select mates with the objective to improve economically important traits. In this chapter, the most common economic traits in different species of livestock are described. Even though the list is not exhaustive the basic economic traits that have been worked for improvement are explained. Breeders also explore new composite traits which are a combination of these base traits.

Traits such as growth, lactation test day yield, semen evaluation are longitudinal traits measured repeatedly on the animal and random regression models (RRM) have been found to be suitable for modeling these traits, The methodology used, data requirement, assumptions, validity, software available and application of RRM are explained in this chapter.

Growth, test-day milk yield, and semen traits are examples of longitudinal traits measured repeatedly on the animal and random regression models (RRM) have been found suitable for modeling such traits. RRM is based on a covariance function which could be defined as “a continuous function to give the variance and covariance of traits measured at different points on a trajectory” (van der Werf, 2001). Kirkpatrick et al. (1990) showed that variance components for longitudinal data can be modelled through covariance functions. Random regression models (RRM) and the resulting covariance function have been recognized as ideally suited for the analysis of longitudinal data (Hill, 1998; Meyer, 1998).

Meta-analyses has been used extensively to combine the results of existing studies and obtain powerful estimates of a parameter. In animal breeding, attempts have been made to obtain meta-analysis estimates for genetic parameters. This tool is more pertinent to animal breeding on account of heterogeneity in terms of location, sample size and other factors in the estimation of genetic parameters. This chapter explains the background, methodology, precautions and implications of meta-analysis with respect to genetic parameters.

A meta-analysis is a powerful tool of statistics that could combine several estimates from different studies for a parameter and the resulting weighted estimate could be used as a representative value for the particular parameter. However, not all the studies are similar with respect to location, sample size, and methodology used and thus various precautions are to be taken right from the selection of studies to incorporating of between-study heterogeneity in the models. In animal breeding, met-analysis is very much useful for obtaining meaningful estimates of genetic parameters and this chapter explains the methodology of meta-analysis in animal breeding.

6.1. Calculation of Energy Requirements for Field Operations
The energy needs for a certain field activity can be determined by adding the amounts of human, bullock, mechanical, and/or electric energy consumed.

Operational Costs for Various Power Sources
Manual power

In the case of human labour, the wages of unskilled employment are charged on an hourly or daily basis (as determined by the location).In the case of research farms, the costs for operating a pair of bullocks are determined on the basis of the cost of a pair of bullocks, the salary of an operator, the cost of bullock feed, and any other expenditures (as imposed in a given location). For the farmer’s fields, however, the real hiring expenses are used as the foundation.

Use Case 1: Supply Chain Traceability

1. Description: Blockchain can enable end-to-end traceability of agricultural products, ensuring transparency and authenticity. It allows tracking the journey of a product from farm to fork, providing consumers with detailed information about its origin, processing, and storage conditions.
2. Current Scenario: The lack of transparency in supply chains often leads to food fraud and safety concerns. Consumers are increasingly demanding more information about the products they consume.
3. How Blockchain Adds Value: Blockchain technology can securely record and store data about each step of the supply chain, including details about farming practices, transportation, and storage conditions. This transparency builds trust and ensures food safety.
4. Statistics: According to a survey conducted by Label Insight, 94% of consumers are likely to be loyal to a brand that offers transparency, including detailed information about product origin and quality.
5. Startups: Provenance, a UK-based startup, uses blockchain to trace the journey of seafood products, promoting sustainability and ethical sourcing.

Abstract

This chapter covers how linear programming aids in reducing costs and maximizing gains. A linear programming problem (LPP) typically contains linear restrictions and an objective function seeking optimization. Initially, two-variable linear optimization models are examined using the graphical technique to comprehend the issue and investigate solutions. The graphical method provides visual insights into the problem’s nature and solutions. Linear programming identifies the mix of choices that optimizes the objective function subjected to constraints. Graphical interpretation aids in recognizing feasible and optimal solutions visually.

Abstract

This chapter discusses the concepts of risk and uncertainty in decision-making. Risk refers to the condition where the decision-maker knows the possible outcomes and their probabilities. Uncertainty refers to the condition where such information is unknown to the decision-maker.

Abstract

Dietary fibre concentrates (DFC) are the major component of fruit by-products generated during the processing at commercial level. These are the blessings for human gut health along with many other positive health benefits. Fruit by-products are the so-called nuisance for the environment that enfolds numerous positive signs inside. Lignin, cellulose, hemicelluloses, pectin, waxes, mucilage’s, oligosaccharide, gums and many other associated compounds are the part of DFCs. These DFCs when taken in the form of functional ingredient reaches to the colonic microbiota and consequently provides them a healthy growth medium that promotes the cell metabolism upto 67%, enhances the growth of good gut bacteria like Bifidobacterium and Lactobacillus. This article enlightens the content of DFCs in various fruit by-products that shows their prebiotic potential.

Introduction

It is the national fruit of India. No other fruit can compete with mango in respect to area, production, nutritive value, and popularity. For this reason, the mango is known as the king of fruits. In India, mango cultivation is 40006000 years old. Growing states are U.P., followed by A.P. and to some extent in all the rest of the states. It is also grown in India, China, Thailand, Pakistan, Bangladesh, Burma, Malaya, Philippines, Sri Lanka, Egypt, Africa, Florida, Hawaii, Brazil, Mexico, etc. Unripe fruits are used for culinary purposes, such as pickles, powder, chutney, and sarbat. Ripe fruits are used for squash, jam, toffee, juice, slices, and canning of pulp and slices.

Introduction

Papaya has long been known as the wonder fruit of the tropics and is one of the five major fruit crops of the tropical world. Papaya fruits throughout the year are a remunerative fruit crop which is grown in almost every part of the country. Next to bananas, it has the highest yield and income per unit. It is generally grown as a fruit plant in kitchen gardens, home gardens, or nutrition gardens and later as a commercial fruit. Papaya is usually dioecious, but hermaphrodite and gynodioecious types are also Recognized. It is the most remunerative crop (highest net return/unit area) of any other fruit crop. India is the 4^th largest producer in the world. Karnataka has the highest production and productivity in India. A valuable proteolytic enzyme is called papain, which helps in the digestion of protein-rich foods. Transgenic PRSV resistant varieties: Sunup and Rainbow were created from coat protein genes grown in Hawaii in 1992.

Pollination is one of the most essential ecosystem services which is effectual for crop productivity, biodiversity and human livelihood. Pollination is the process of transferring pollens from anther to stigma for plant reproduction and has direct impact on crop productivity. Conservation and management of pollinators is still ignored in the agriculture development program by the policy makers. In agricultural ecosystem, many agricultural crops are dependent on insects for their pollination, and assisted pollination may have to be done when natural pollination is insufficient in order to reduce potential yield loss (Klein et al., 2007). About 80% of the world’s flowering plant species are dedicated to animal pollination, mostly by insects (FAO, 2007). In 2005, globally, pollinators’ pollination services economic value was estimated to be about €153 billion (Gallai et al., 2009). The United Nations also reported that the economics of ecosystems and biodiversity by insect pollination was valued at £134 billion.

Agricultural biodiversity is known as crop genetic resources, although agroecosystems hold a wide diversity of other organisms that contribute toward their productivity and sustainability. Amongst these pollinators play the massive role in crop pollination and thus ensure that fruit or seeds are formed. Over 3 decades ago, the international community began to emphasize on the importance of pollinators. In agro-ecosystems, pollinators are essential for agriculture, horticultural and forage production as well as the production of seed for many root and fiber crops. Pollinators such as bees, birds and bats affect 35 per cent of the world’s crop production, increasing outputs of 87 of the leading food crops worldwide, plus many plant-derived medicines in our pharmacies (Klein et al., 2007). Food security, food diversity, human nutrition and plant diversity all rely strongly on animal pollinators. Pollination is an essential ecosystem service that enables plant reproduction and food production. The pollinators’ abundance and diversity play pivotal role for enhancement of the productivity, quality and maintenance of natural resources of plant biodiversity. The diminution of pollination abundance and their diversity certainly affect productivity, quality and plant biodiversity.

Pollinators are organisms that help to transfer pollen from anther to stigma of the same species for fertilization and thereby produce seeds and fruits. Pollinators belong to diverse groups viz. insects, birds, reptiles, mammals, etc. Insects; bees butterflies, moths, wasps, flies, some types of beetles. Out of insect pollinators, bees are most important pollinator. Insect pollinators are critical to the production of many crops and play pivotal role to maintain the biodiversity. The decline in honeybee and other pollinator populations have more attention of scientific and public concern globally as well as in India. A number of factors have been observed as potential contributors to these declines and no single factor has been identified as the cause. The available science suggests that multiple factors responsible for population depletion and extinction, including loss of habitat and food sources, diseases, viruses, pests, and pesticide exposure. It is also known that certain pesticides can pose an immediate or “acute” threat to the insect pollinators and bees. In order to protect pollinators, the labels of pesticides that pose such risks should specify detailed directions of application to reduce potential exposure.

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.

In modem days, many informations receive through electronic media with instant connecting by satellite based information on social, economical, environmental etc. the informations are coded with feasible electronic encrypt and delivered to people. Similarly remote sensing, GIS (Geographical Information System) and GPS (Global Positioning System) also serve world for better understanding the ground reality along with reducing cost of operation, transforming data through electronic webs easily. In earlier phase, ground related information was not easily obtained because all kind of work had been done manually using analog maps of earth; even map draw was done by drafting from totposheet or hand maps, no interface of analog and digital world.

The information of image is perfectly accepted by eyes when the image will be in convenient form. Always pictures accurately detail about information related to their position, sizes and inter-related with each other is objects. Actually images portray positional information which can be recognized as objects. Human eyes are exact example for differentiating that information from images to innate visual and mental ability.

Despite of pandemic the Indian economy has been growing consistently and Agriculture sector also maintained the momentum. Let us have an overview of investments in India’s agritech startups during 2019-2022:

1. Total investment: $2.5 billion
2. Number of deals: 234
3. Average deal size: $10.7 million
4. Top sectors: Market linkage (52%), Farm management (25%) & Agri- inputs (18%)
5. Key drivers of investment: Growing demand for food and agricultural products, Increasing adoption of technology in the agricultural sector and Government support for the agricultural sector

The Rochdale Society of Equitable Pioneers was founded in Rochdale, England, in 1844 and soon became a prototype for cooperatives worldwide. Its governance structure, known as the Rochdale Principles, is still a key guideline for the design of cooperatives. The social dislocations of the Industrial Revolution inspired workers and enlightened entrepreneurs to establish cooperative societies since the beginning of the nineteenth century.

In case of proprietorship business, the individual proprietor generally invests his own savings to start with, and may borrow money on his personal security or the security of his assets from others. Similarly, the capital of a partnership firm consists partly of funds contributed by the partners and partly of borrowed funds. But the company from of organization enables the promoters to raise necessary funds from the public who may contribute capital and become members (share holders) of the company. In course of its business, the company can raise loans directly from banks and financial institutions or by issue of securities (debentures) to the public. Besides, profits earned may also be reinvested instead of being distributed as dividend to the shareholders.

Thus for any business enterprise, there are two sources of finance, viz, funds contributed by owners and funds available from loans and credits. In other words the financial resources of a business may be own funds and borrowed funds.

Technology spurs Agricultural productivity through various scientific methods and innovations which is evidenced by the success of the Green revolution leading to agricultural development.

The Green Revolution arrived in India in 1968 and had a remarkable impact on the world of agriculture by increasing production yield by 2.5 times, amounting to approximately 2 billion tones, which has been noted as the world’s highest growth rate in the agriculture sector. Because of the science and technologies used in the form of

Pump is a mechanical device to increase the pressure energy of fluid. Aquacultural enterprises often find it necessary to move fluid against an energy gradient. Most commo n may be filling or emptying of tanks. For performing an assigned job, the best selection of pumps should be such that it should work at its peak efficiency. Unfortunately, there is only one head and discharge condition for each pump where the peak efficiency is obtained and therefore, it is rarely possible to achieve the highest efficiency for a pumping condition. Manufacturers cannot design and build so many varieties of pumps to meet all operating conditions. They have therefore, settled upon some standard designs which are generally required for most of the head and discharge conditions.

The feeding is an important operation in aquaculture, it is the process of providing nutritious supplements or live feeds to the culture animal. The equipment used for this purpose is named as feeders. Equipment that is connected with fish feeding can be divided into three major groups, as follows

Material handling includes a number of operations that can be executed either by hand (manual) or by mechanical means or devices to convey material and to reduce the human drudgery.

The most common types of mechanical devices for grain handling are;

A microwave oven, commonly referred to as a microwave, is a kitchen appliance that heats and cooks food by exposing it to electromagnetic radiation in the microwave spectrum.

The refrigerator (called a ‘fridge’ by most people) is a box like equipment which uses electricity to keep the temperature inside the box lower than the atmosphere outside. Food kept at such a low temperature thus does not spoil for a long time. The refrigerator also serves the purpose of giving us cold water and ice in summer. By preserving food in the refrigerator, one can delay the growth of bacteria, keep food items fresh and thus save time and energy of the homemaker in meal preparation.

Milk is considered to be a perfect food which contains almost all the macroand micronutrients required for normal body growth. However, it is highly perishable in nature which poses problem during its storage. It gets spoiled within few hours after milking if not processed or cooled immediately. It can also be a source of several disease causing microbes as it is conducive for the growth of microorganisms.

Thermal heating methods are used from long time to decontaminate the food products from microorganism and therefore increase its shelf life and ultimately make the product safe for human consumption. But these methods diminish the sensory, physicochemical and nutritional properties of food (Barba et al., 2012). Also, the cost of generation of heat in manufacture of food product make the product costlier in thermal processing and also create environmental issue.

The last two decades have seen rapid growth and development in the industrial sector as well as urbanization has increased. Due to globalization and mass production of commodities, the situation in the modern world nothing like ever before. Food and dairy industries are also not left out from this massive expansion. Due to changing behavior and food consumption habits too, there has been a surge in the risk of foodborne illness. This has created a problem in terms of public health and sustainability

The term nanoscience defines controlling or modifying the shapes and sizes of the materials such that they lie in the range of a nanometre (1 nm = 10^-9 m) scale, typically 1-100 nm (Chavada et al., 2016). The application of these materials and systems by their suitable designing and production is what is known as nanotechnology. Richard Feynman, in 1959, first discussed the possibility of this advanced technology. However, the term was first used by Norio Taniguchi in 1974 (Chavada et al., 2016).
