Introduction

In the last two decades global climate change has perceptible and marked impact on the monsoon pattern in India. Delayed and inadequate monsoon has become a recurrent feature and the country is in the grip of drought-flood cycles. Right from the beginning of large scale irrigation that brought green revolution and food self sufficiency to the country, there is a strong feeling that full potential of rivers of the country is not tapped (Table 1).

Animal husbandry faces increasing pressure to produce safe milk, meat and eggs while improving animal welfare and reducing environmental impacts. Traditional observation-based management is increasingly inadequate for large and complex livestock systems. This chapter introduces digital transformation through Precision Livestock Farming, which combines IoT devices, smart sensors, wearables, computer vision, artificial intelligence, machine learning and digital twins. Continuous animal-centred data enables timely decisions concerning health, reproduction, feeding, behaviour and welfare. The chapter explains how digital technologies can support early disease detection, efficient resource use and improved productivity across commercial and smallholder farms, creating more profitable, sustainable and welfare-conscious livestock systems.

Biology is the study of life and living organisms that encompasses a vast range of topics from the microscopic scale of cellular processes to the complex interactions within ecosystems. It explores living organisms’ structure, function, growth, evolution, and distribution, integrating diverse fields such as genetics, ecology, and physiology. Chemistry is often referred to as the central science, delves into the composition, structure, properties, and changes of matter. It explores how substances interact with each other and transform through chemical reactions. This field underpins a multitude of scientific disciplines, linking concepts in physics with applications in biology, medicine, and engineering. The chemistry of living organisms is known as Biochemistry. The concept behind Biochemistry deals with the biology and the conventional chemistry. As we all know living organisms can grow, reproduce, and respond but do you know that all these activities could easily be interpreted by chemistry? The complex organic molecules are present

Confectionery is the art of making confections, which are food items that contains high quantity of sugar and carbohydrates.

Traditional confectionery goes back to ancient times, and continued to be eaten through the Middle Ages into the modern era.

Confections include sweet foods, sweetmeats, digestive aids that are sweet, elaborate creations, and something amusing and frivolous. Confectionery, delicacies or sweetmeats that have sugar as a principal ingredient, combined with coloring matter and flavoring and often with fruit or nuts.

Confections are low in micronutrients and protein but high in calories.

1.1. Introduction

Dairy animal production in the last few decades witnessed tremendous growth throughout the world. The remarkable success of the dairy animal production can be attributed to the constant efforts of researcher, planner as well as producer. At present dairy farming is becoming a commercial activity. Hi-tech dairy farms produce high quality milk for making value added milk products for competitive markets around the world. The management of the dairy farming enterprises is crucial for the sustainability and profitability of it. The effective management of dairy animals essentially emphasizes the following areas:

Evolution of Economics as a Discipline
1. Initially, economics was not a separate subject but a part of politics, ethics, and jurisprudence.
2. The study of economic ideas gained prominence through discussions on wealth, trade, and resource management.
3. Adam Smith’s book, An Inquiry into the Nature and Causes of the Wealth of Nations (1776), established economics as a distinct discipline.
4. Due to his contributions, Adam Smith is regarded as the Father of Economics.
Origin of the Term “Economics”
1. The word Economics is derived from the Greek term “Oikonomikos”:
a) Oikos – Household
b) Nomos – Management
2. Originally, Oikonomikos referred to the management of household affairs.

This chapter introduces egg science and technology as a multidisciplinary field combining biology, physiology, chemistry, microbiology, nutrition, engineering and food technology. It discusses the historical development of egg use and processing and examines the position of eggs as a major global and Indian food commodity. The chapter explains the structure and growth of the Indian egg industry, production and consumption trends, economic and nutritional importance, and the complete egg value chain from breeding and feed through farm production, grading, processing and consumption.

1. Sample: One or more units selected from a population of units, or a portion of material selected from a larger quantity of material
2. The Standard Operating Procedures (SOPs) should contain full working instructions as well as information on applicability, expected performance, internal quality control (performance verification) requirements and calculation of results. It should also contain information on any hazards arising from the method, from standards or from reagents.
3. Analytical Samples: The quantity of the analytical sample to be used is usually indicated in tests and assays. Unless otherwise specified, the quantity used may deviate by 10% from that stated. All quantitative determinations should be conducted on triplicate test portions and in these cases, the amount actually taken should be accurately weighed or measured and the result of the analysis calculated on this exact quantity. When substances are to be “accurately weighed” in a test or assay, the weighing is to be performed in such manner as to limit the error to ± 0.1% or less. Quantities smaller than 100 mg should be weighed to the nearest 0.1 mg.

In today’s global food industry, packaging has evolved into an essential component that extends beyond basic containment. The rapid expansion of food distribution networks and increasing consumer demand for quality, convenience, and safety have transformed packaging into a sophisticated, multi functional system. Food packaging now serves critical roles in preservation, safety, marketing, and sustainability, aligning with both global and regional standards that cater to a wide array of consumer needs. This chapter provides an overview of the importance of food packaging, discusses the current landscape in both global and Indian markets, identifies key trends and challenges, and explores packaging’s role in the modern food supply chain. Each section aims to illustrate how food packaging impacts food quality, longevity, and overall consumer satisfaction, highlighting the industry’s ongoing innovations and adaptations to regulatory and environmental concerns. 1.1 Definition and Significance of Food Packaging Definit

Food processing is a fundamental component of the food industry that transforms raw materials of plant and animal origin into safe, nutritious, convenient and value-added products. This chapter introduces the basic concepts and evolution of food processing, tracing its development from traditional practices to modern technologies driven by consumer demand. It explains the major purposes of processing, including shelf-life extension, food variety, safety and preservation of nutritive value. The chapter also examines primary, secondary and tertiary processing and discusses the effects of processing on macronutrients and micronutrients. Understanding these fundamentals provides a foundation for evaluating conventional and emerging food-processing technologies.

Introduction
Good Laboratory Practices (GLP) are a quality system concerned with the organizational process and the conditions under which non-clinical health and environmental safety studies are planned, performed, monitored, recorded, archived, and reported. GLP ensures the quality and integrity of the study process rather than the scientific validity of the study itself. It provides a framework for ensuring that data generated in non-clinical safety studies are reliable and reproducible, thereby facilitating the mutual acceptance of data by regulatory authorities worldwide (OECD, 1998; US EPA, 2016). GLP represents a structured quality system designed to ensure the consistency and reliability of non-clinical safety studies. It establishes a framework encompassing organizational processes and laboratory conditions, with a focus on:
1. Systematic Study Conduct: GLP mandates a methodical approach to the planning, execution, supervision, recording, reporting, and archiving of studies.
2. Data Integrity Assurance: The primary objective is to guarantee the dependability of data generated, thereby fostering confidence in safety assessments.
3. Regulatory Compliance Support: GLP facilitates adherence to regulatory standards, enabling the acceptance of study findings by authorities worldwide.
4. Non-Clinical Safety Focus: It specifically applies to studies that precede human clinical trials, particularly those evaluating the potential hazards of chemical substances (OECD, 1998).
In veterinary and allied fields, GLP extends beyond general scientific rigor to address the unique challenges of animal health, food safety, and environmental protection related to animal populations. It ensures the reliability and traceability of data generated in studies related to veterinary pharmaceuticals, feed additives, diagnostics, and environmental toxicology involving animals. The focus is on maintaining the integrity of studies that directly impact animal welfare, public health, and agricultural sustainability (World Organization for Animal Health, 2018; FDA, 2010). In the context of veterinary medicine or treatment aspects, GLP in veterinary refers to a a well organised quality system that governs the organization and conditions under which non-clinical studies related to animal health and safety are planned, performed, monitored, recorded, reported, and archived. This includes:

The science of Meteorology is defined as the science that deals with physical and chemical processes of the lower atmosphere. The physical and chemical changes in the lower atmosphere produce weather and popularly known as the weather science. The weather science concerns the study of structure, state and behaviour of the lower atmosphere. It is essentially an observational science dealing with different atmospheric variables such as atmospheric pressure, temperature, wind, humidity, density, cloud amount, radiation, precipitation and related variables at a given moment and attempts to predict the behaviour of atmosphere over a period of few hours to few days ahead and disseminate the same in time to the users? community. The statistical approach of weather phenomena deals with the mean state of the physical properties of atmosphere. This branch of science is popularly known as Climatology. The weather science can be categorized into several branches based on method of approach, purpose and function, scale and region. Based on the purpose and function, it can be divided into several branches like Livestock Meteorology, Agro Meteorology, Forest Meteorology, Hydro Meteorology and Bio-Meteorology (Fig 1.1).

Animal husbandry is the most important economic activity in rural areas as livestock plays a vital role in the economy. Over 90 per cent of the milk production comes from small farmers, who are located in rural areas. Growing human population, increasing urbanisation, rising domestic incomes and changing lifestyles in the country have led to increasing demand for dairy products (Anita and John, 2001).

Introduction
Generally, muscles and offals obtained from animals feeding on grass and various other cultivated crops are regarded as meat. Apart from the meat obtained from the cattle, sheep, goat, pig and poultry, in many countries particularly Denmark, Belgium, Holland and Germany, horse meat is also consumed (hippophasia) as normal meat. Kangaroos are slaughtered for meat in Australia whereas capybara a large semi-aquatic vegetarian rodent, is used in South America as of one of the meat source. Dog meat (fragrant) is relished (Kinophasia) in few cultures such as South Korea, China, Vietnam and few north eastern states of India.
In many parts of the world including Indian subcontinent, buffalo meat (Bubalus bubalis), also known as water buffalo or arna, is quite popular owing to its tenderness, leanness and low cholesterol qualities. It is distributed in many countries around the world such as India (largest population), Pakistan, China, Bangladesh, Indonesia, Philippines, Hungary, Italy and France etc. Bison (Bison bison) from North America is also called buffalo but they are separate species of the order Bovidae. Rabbits are also source of meat having higher growth rate and better feed conversion ratio (2:1). Elands are another meat source which are raised in Africa and Russia for meat purpose.
Meat is quite high in protein content but the presence of saturated fat is perceived negatively due to its association in various cardiovascular diseases, diabetes etc. Efforts are made to produce lean meat having higher content of unsaturated fatty acids and to reduce the ω-6 to ω -3 fatty acids ratio.

Introduction

R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R.

R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering) and graphical techniques, and is highly extensible. The S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity. In a nutshell, R is an open-source software environment for statistical computing that is rapidly becoming the tool of choice for data analysis in the life sciences and elsewhere. It’s developed by a large international community of scientists and programmers and is at the forefront of new developments in statistical computing.

In textile manufacturing, fibers serve as the fundamental components of raw materials, distinguished by their length, flexibility, and strength, which enable them to be spun into yarns and woven into fabrics. Extremely long fibers are referred to as filaments. Fibers can be classified as natural, derived from plants, animals, or minerals, or artificial, produced through chemical processes. Natural fibers are those sourced directly from animal, vegetable, or mineral origins and can be utilized for creating nonwoven fabrics or spun into yarns for woven textiles. Typically, they are significantly longer than they are wide. Although nature offers a variety of fibrous materials, including cotton, wood, grains, and straw, only a select few are appropriate for textile applications. The appropriateness of a fiber is determined by its length, strength, flexibility, elasticity, abrasion resistance, absorbency, and surface characteristics. Most textile fibers are slender, flexible, robust, and elastic, allowing them to stretch and revert to their original form.
During the 18th and 19th centuries, the Industrial Revolution brought about significant advancements in machinery for processing natural fibers, resulting in increased fiber production. This era saw the introduction of regenerated cellulosic fibers such as rayon, which is produced by dissolving and purifying cellulose, followed by the emergence of synthetic fibers like nylon, which began to compete with the supremacy of natural fibers in the textile industry. Synthetic fibers, with their distinct advantages, started to supplant natural fibers across various sectors. In reaction to this shift, there was a surge in research aimed at enhancing natural fibers through improved strains, advanced production techniques, and modified properties of yarns and fabrics. Nevertheless, synthetic fibers, being more economical and less labourintensive, captured a larger share of the market.

This chapter introduces wool as a natural, renewable and biodegradable keratin fibre produced by sheep. It explains the distinction between wool, hair and kemp and examines the historical development of wool sheep and the global and Indian wool industries. The chapter discusses the biological, physical and economic characteristics that make wool an important animal fibre. It also introduces wool's role in sustainable textiles, its value chain and the institutions involved in research, standards and development.

India is one of the chief carpet wool producing and exporting countries of the world. A large quantity of carpet wool is exported to the developed countries. Wool production in Indian subcontinent is mainly dependant on distinct type of sheep producing wool in a particular geographical area. For example small and course wool is produced by Bikaneri breed in North Western India, course wool by Deccani breed and hair type breed by Mandya breed in Peninsular India and fine wool is produced in Himalayan region. In general, tropical breeds of sheep are mainly producing course wool which is highly suitable for carpet manufacture. Most of the Indian sheep breeds are producing low fleece yield. The annual total yield of greasy wool is in the range of 1-1.5 Kg. Overall great quantity of wool is produced in southern hemisphere but consumption is in northern hemisphere.

Several centuries ago, perhaps as early as 6000-8000 BC, ancient man learned to domesticate species of animals for obtaining milk for their consumption. These included cows, buffaloes, sheep, goats, and camels, all of which are still used in various parts of the world for the production of milk for human use. The significance of milk as the most wholesome single food available in nature has never been debated. It is as ancient as mankind itself. The role and consumption pattern of milk in the traditional diet varies widely in different regions of the world. The tropical countries have not been traditional milk consumers, whereas in Europe (especially Scandinavia) and North America, milk and milk products have been traditional parts of the diet.

The term “nutraceutical” was coined from “nutrition” and “pharmaceutical” in 1989 by Stephen DeFelice, MD, founder and chairman of the Foundation for Innovation in Medicine (FIM), Cranford, NJ. According to DeFelice, nutraceutical can be defined as, “a food (or part of a food) that provides medical or health benefits, including the prevention and/or treatment of a disease”. In other words, nutraceuticals are chemical or natural feed ingredients which may enhance health by providing a physiological benefit by the provision of basic nutrients. Enzymes, prebiotics, probiotics, yeast and fungal extracts, predigested hydrolyzed carbohydrates and fats, phytogenic additives, acids etc are included in nutraceuticals. However, the term nutraceutical as commonly used in marketing has no regulatory definition.
