1 Human and Animal Interactions in the Ecosystem
1.1 Evolution

It is proved that humans and animals share common ancestors as per evolution process. Thus, it is likely that, animal capacities are similar to humans, but these capacities differ only in degree. Furthermore, if the capacity for a particular feeling gives an adaptive advantage to an animal, then this provides supportive evidence for its existence. The presence of very similar neurological structures in other animals constitutes some sort of evidence that they can have the same sorts of mental states as humans. In the process of evolution depending on the favourable and unfavourable environmental factors, few organisms may die and few organisms might multiply. The relationship between biotic and abiotic components helps in the formation of ecosystem. In this ecosystem each and every organisms have equal chance to survive. The evolution process is well explained by Darwin’s theory.

Introduction

Nutrition, a basic human need, is a critical part of health and development. Nutrition can be defined as the intake of food, deliberated in relation to the body’s dietary needs. On one hand, good nutrition – an adequate, well balanced diet combined with regular physical activity – is a foundation of good health, whereas,poor nutritionleads toreducedproductivity,impairedmental andphysical development, increased susceptibility to disease, and reducedimmunity. According to WHO, under-nutrition, together with vitamin and mineral deficiencies accounts for one-third of all child deaths and impairs healthy development and lifelong productivity. At the same time, sedentary lifestyles, demographic shifts, urbanization and the liberalization of markets have steered the world population to being overweight along with risk of chronic diseases like hypertension, dyslipidemia, type 2 diabetes, coronaryheart disease, stroke, etc.; thus, resulting in a double burden of malnutrition.

To address this dual burden of malnutrition, individuals needaccess to sufficient and good quality food; but focussing solely on food security is unlikely to solve the problem of global malnutrition. The challenges of malnutrition cannot be solvedjustbyincreasingfoodproductioninordertoimprove healthand nutritional status of the population. To resolve such challenges, awareness about food choices for optimal health plays a pivotal role among population.

Human nutrition is the science of understanding food; its component; intake; and how it is related to health, growth, development and diseases. Human nutrition involves the study of ingestion, digestion, absorption and assimilation of the nutrients; their metabolic functions, deficiency or excess disease as well as their regulation through several factors such as choosing particular food components/nutraceuticals or physical activity.

Population Growth
Around 1810, it took all of human history for the population to reach one billion. This quadrupled to 2 billion people in just 120 years (1930). Then, in 45 years, 4 billion (1975). From 4.4 billion in 1980 to 5.8 billion in 1997 and 7 billion now, the world’s population has increased. It is predicted that in less than 40 years, that number will double again to 11 billion. This indicates that more people than ever before are joining the group every day.
The United Nations Population Fund (UNPF) predicts that by 2025, there will be 10 billion people on Earth, and by the next century, there will be 14 billion.
Birth rates have decreased along with mortality rates, although death rates have decreased more quickly. In most affluent countries, there are approximately 1.6 births for every death, but in less developed countries, the ratio is closer to 3.3 births for every death. Every twelve years, a billion more people live on the planet.
Reasons Behind the Quick Population Growth
• A rise in the distribution and production of food.
• Gains in the field of public health
• medical technology, as well as improvements in education and living standards in many poor countries.

Humane slaughter is an act of killing the food animals in such a way as to cause the minimum stress or distress to the animal. To achieve this objective animal must be rendered insensible instantaneously and remain insensitive to pain until there is a complete loss of brain responsiveness due to exsanguination. The unconsciousness in animals is induced by stunning procedures which are varying in number. The method of stunning primarily based on species, breed, age, sex, kind and mental state of animals. Stunning is essential to safeguard the feelings and anxieties of animals. It facilitates maximum bleeding from the animals because animal becomes unconscious after stunning. To make animal unconscious before bleeding is not only essential for animal welfare point of view but it is legislation in many countries.

Introduction

Water is among the most precious gifts of nature to mankind. Most of the ancient towns of the world grew on the banks of the river, and some of the ancient civilizations are known by the names of rivers. Rivers have always been important sources of drinking water and the means of sustaining human, animal and plant life. Whenever one is dealing with water resources development and utilization, it has to be kept in mind that not only quantity of water but also quality of water is very important. The well being and development of our society is dependent on the availability of water. An increase in groundwater development and utilization for industries and urban water supply has created improper disposal of liquid waste. Defective well constructions, sewage and waste disposal in man made lakes with in the city, open quarries with water and failure to seal the abandoned wells in city area have provided possible openings for downward movement of polluted water into subsurface formations without undergoing the process of natural filtration.

6.1. INTRODUCTION

The word hypothesis is made up of two words Hypo + thesis = Hypothesis. ‘Hypo’ means tentative or subject to the verification and ‘Thesis’ means statement about solution of a problem.

The world meaning of the term hypothesis is a tentative statement about the solution of the problem. Hypothesis offers a solution of the problem that is to be verified empirically and based on some rationale. Hypothesis is the composition of some variables which have some specific position or role of the variables i.e. to be verified empirically. It is a proposition about the factual and conceptual elements. Hypothesis is called a leap into the dark. It is a brilliant guess about the solution of a problem. A tentative generalization or theory formulated about the character of phenomena under observation are called hypothesis. It is a statement temporarily accepted as true in the light of what is known at the time about the phenomena. It is the basis for planning and action in the research for new truth.

Ice cream over the years has come to acquire an easy acceptance as a healthy, nutritious and hygienic food for the aged, sick, growing children and adults. Its popularity, as demonstrated on all types of occasions is growing fast and its potential appears to be unlimited.

Gone are the days when the word “Ice Cream” was synonymous with strawberry and vanilla flavours or the innocuous orange. Ice cream is available in many forms, flavours and packages. Today, there are exotic variations to titilate the palate, such as Jingle Bells, Goody goody Gum Drops, Champagne Snowballs, Mr. Frost, Tutty Fruity, Butter Scotch, etc, waiting to launch customers on a gastronomical voyage.

It is uncertain how long ice cream has been produced, however, the International Association of Ice cream Manufacturers (1966) traces the beginnings of ice cream and frozen desserts to iced drinks enjoyed by Alexander the Great in the fourth century B.C. down through the years Nero in the first century A. D., Marco Polo in the 13^th century through Italy and France to England in 1643-1649, and to America around 1700. From a very old writings it has been learnt that the Chinese liked a frozen product made by mixing fruit juices with snow, what we now call water ice. It is believed that ice cream evolved from iced beverages and water ices that were popular in the medieval period. This technique later spread to ancient Greece and Rome, where the wealthy, were partial to frozen desserts.

After disappearing for several centuries, ice creams in various forms reappeared in Italy in the Middle Ages, most probably as a result of Marco Polo returning to Italy in 1295 after a 16-17 year stay in China, where he had learnt to appreciate a frozen dessert based on milk. There is no gainsaying the fact that the true origin of ice cream cannot be proclaimed with a fair measure of certainty but, all the same, the Italians claim that Benaroo Bountalenti, a resident of Tuscany, invented ice cream in the early 1300s. From Italy ice cream spread over Europe during the 17^th century, and for long remained a luxury product for the royal courts. Italian ice cream was very popular in London around 1870.

A greenfield ice cream project involves much more than installing production machinery. It requires integrated planning of the business model, market opportunity, capacity, product portfolio, plant layout, process technology, refrigeration, utilities, packaging, cold storage, quality systems, regulatory compliance, distribution, working capital, and future scalability. This chapter presents a practical framework for evaluating new ice cream manufacturing projects, with particular attention to a representative 1000 LPH facility. Different project scales and business models are considered along with major plant and machinery requirements. The chapter also highlights common project-planning mistakes and best practices. It helps entrepreneurs and investors assess technical feasibility, operational readiness, financial requirements, scalability, and long-term commercial viability.

India is emerging as one of the most dynamic ice cream markets, with growing demand driven by urbanisation, rising disposable income, premiumisation, regional flavours, modern retail, quick commerce, and expanding cold-chain infrastructure. This chapter examines the evolution and structure of the Indian ice cream market, major growth drivers, consumer segments, competitive conditions, and emerging opportunities. It also considers important challenges including seasonality, freezer investment, cold-chain reliability, SKU complexity, regulatory compliance, working capital, and market returns. The chapter provides strategic guidance for entrepreneurs and manufacturers on market entry, positioning, product portfolios, distribution, and sustainable growth in India’s increasingly competitive ice cream industry.

Blood Sample collection

Blood samples (5 ml per goat) will be collected aseptically from the jugular vein in a vacutainer tube (B.D. Bioscience, Germany) containing EDTA as anticoagulant and transferred to the laboratory in an ice box.

Isolation of Genomic DNA

The Genomic DNA will be isolated from the blood samples by ‘Phenol: chloroform isolation’ method as described by Sambrook and Russel (2001). The steps for isolation of genomic DNA are as follows:

SOURCES OF LOSSES
In most of the cases of excessive fat or product loss, a combination of several factors rather than any single factor are responsible.
 
Inaccuracy in weighing: Receiving room scales should be checked regularly with a set of weights. The check should be made immediately before weighing operations begin. Improper drainage of the weighbowl will permit a carry over into the next batch dumped, resulting in incorrect weighing. Errors in weight in bulk handling methods may be caused also by improper leveling of the tank, incorrect calibration of the measuring rod, or carelessness on the part of the person taking the measurement.
 
Inaccuracy in sampling: Failure to collect representative samples may sometime cause sizeable losses. Milk should be properly agitated before taking samples. The composite sample should be preserved and refrigerated and should be protected from mould growth.

Introduction
Antimicrobial resistance (AMR) represents one of the most significant public health challenges of modern times. The discovery of antibiotics in the early 20th century revolutionized medicine, transforming once-fatal infections into manageable conditions and enabling life-saving procedures such as organ transplantation, chemotherapy, and joint replacement surgery. However, the overuse and misuse of antibiotics in human medicine, veterinary practice, and agriculture have accelerated the development of resistant microorganisms. Today, infections caused by resistant pathogens claim millions of lives worldwide each year, with the World Health Organization warning of a postantibiotic era in which minor injuries or routine surgeries could again become life-threatening. Although AMR is often framed within the context of hospital-acquired infections and clinical treatment failure, its implications extend much further. In particular, AMR has significant consequences for physical and health fitness. For athletes, soldiers, patients in rehabilitation, and physically active individuals, resistant infections can disrupt performance, delay recovery, and compromise long-term health. The increasing prevalence of resistant organisms in community environments—including gyms, swimming pools, and sports facilities—further raises concern. This chapter situates AMR at the intersection of clinical medicine, sports science, and community health. It explores how resistant pathogens affect physically active populations, complicate rehabilitation processes, and influence outcomes in both competitive and recreational Fitnes. It also highlights the global and national responses to AMR, preventive strategies relevant to Fitnes and rehabilitation, and the role of healthcare professionals

Introduction

According to the Intergovernmental Panel on Climate Change, climate change refers to the long-term changes (typically decades or longer) in the average state of the climate with statistically significant variations.

The climate change, defined as the long-term imbalance of customary weather conditions such as temperature, radiation, wind and rainfall characteristics of a particular region, is likely to be one of the main challenges for mankind during the present century.

A general definition of climate change is a change in the statistical properties (principally the man and spread) of the climate system when considered over long periods.

Climate Resilience

Climate resilience can be generally defined as the capacity for a socioecological system to: Absorb stresses and maintain function in the face of external stresses imposed upon it by climate change. Adapt, reorganize, and evolve into more desirable configurations that improve the sustainability of the system, leaving it better prepared for future climate change impacts.

Introduction

Birds lack sweat glands; hence non-evaporative cooling mechanism (radiation, conduction and convection) is the major route of heat dissipation within thermoneutral range. Beyond this TNZ, majority of heat loss occurs as insensible heat loss i.e., Panting. Panting is one of the visible responses in poultry during exposure to heat stress associated with considerable energy expenditure. This specialized form of respiration dissipates heat by evaporative cooling at the surface of the mouth and respiratory passage. Panting increase, the loss of CO2 from the lungs, this leads to a reduction in the partial pressure of CO2 and also reduces bicarbonate levels in blood plasma. In turn, the lowered concentration of hydrogen ions leads to rise in plasma pH, a condition generally referred to alkalosis (Daghir, 2009). Birds also respond by reducing their feed intake and thus metabolizable energy (ME) intake to reduce thermo genesis as an adoptive mechanism. If panting fails to prevent their body temperatures from rising, the birds become listless, comatose and soon die due to respiratory, circulatory or electrolyte imbalances (Saif et al., 2003).

Foot and mouth disease (FMD) is the most contagious disease of animals and has a great potential for causing severe economic losses in susceptible cloven-hoofed animals. FMD has been classified as a Transboundary Animal Disease (TAD) which is highly contagious or transmissible and has the potential for very rapid spread, irrespective of national borders, and causing serious socio-economic consequences. FMD has constituted a recognised threat to the health of livestock for over 500 years and still remains a serious hazard to the productivity of animal populations throughout the world. The large numbers of virus serotypes and subtypes, the ease of transmission and the limited efficacy of vaccination make control complicated and difficult. Contribution of environmental variables for emergence and distribution of infectious diseases has long been recognized by many researchers. India is largely subject to four seasons: winter (January and February), summer (March to May), a monsoon (rainy) season (June to September), and a post-monsoon period (October to December). There are reports on effect of environmental parameters such as relative humidity, windspeed and air temperature on the spread of the disease. FMD is endemic and at a high prevalence in many countries in Africa, the Middle East and Asia and is also present in parts of South America. Europe, North and Central America, the Pacific nations and the Caribbean are free from the disease. FMD in India is the biggest impediment to growth of livestock sector. FMD outbreaks occur in India throughout the year. The outbreaks occurred round the year with maximum occurrence during October to March, and in May and June (Fig. 15.1). Foot and mouth disease is associated with an aphthovirus (family picornaviridae) which occurs as seven major serotypes: A,O,C,SAT1, SAT2, SAT3 and Asia1. FMD is characterized by fever, profuse salivation, vesicles in the mouth and on the feet and a drastic reduction in milk production; sudden death in young stock may occur (Radostits et al., 2006).

In the existing planetary system, life was established and growing over millions of years on earth. If we track down to the history of evolution, beginning with a living unicellular organisms Amoeba, growing to a gigantic size of Dinosaur and stabilizing at well adaptable stage of an Elephant in animal kingdom or to reach the present status of the intelligent human being, throughout these developmental stages the climatic/meteorological factors play a crucial and supportive role. Further the Development of plant/Animal kingdom is making rapid strides in tropical climatic zones where the temperature ambient ranges between 20⁰C to 40⁰C and the rain fall/humidity factors are moderate. We are fortunate enough that India is geographically located in tropical zone. This classic location advantage of the country in the world geographical map helped the country in keeping India as number one milk producer in the world, no 3 producer in poultry egg production, number 5 in horticulture production i.e fruits and vegetables. Climate change affects livestock both directly and indirectly. Direct effects from temperature, humidity, rainfall, wind speed and other climate factors, aggravates the heat stress in dairy animals, and influences animal performance badly: in growth factors, milk production in Dairy animals, mutton production/ wool production in case of sheep. egg and meat production in poultry, and reproductive aspects in all the species. The indirect impact of these factors on livestock may result on economic, nutritional and health aspects of human society and also its contribution to the economy of the country.

Introduction

Poultry production is one of the fastest growing sectors of livestock industry in developing countries. Environmental variation is one of the major factors that affect sustainability of poultry production systems in tropical climate (Sinha et al., 2017a). Adverse climatic stress declines the production performance of chicken which causes high economic loss to the enterprises as well as the farmers. Heat stress has an adverse effect on egg production, egg weight and shell quality of laying hen (Whitehead et al., 1998). Climatic variables like temperature, humidity, radiation and wind speed that directly affect the mechanism of thermoregulation and rates of heat exchange by all animals (NRC, 2001). Heat stress is a major factor that decreases productivity and reproductive efficiency of livestock due to lower feed intake and negative energy balance (De Rensis and Scaramuzzi, 2003). Moreover, it badly affect the production due to decline feed digestibility such as proteins, fats, starch (Bonnet et al., 1997). In addition, the acute heat stress drastically decreases the reproductive performance of hens due to alterations in acid-base balance and ion exchange mechanism (Mahmoud et al., 1996). Climate change in?uences the emergence of disease and their transmission due to increases vectors, pathogens. All the above effects impact a huge economic loss to the farmers as well as the country.

Livestock is considered one of the essential variables in the revenue of a farmer. The sector (excluding fisheries) contributes 30 per cent to India’s agriculture gross domestic product, and it is valued at more than Rs. 9 lakh crores. India is also one of the largest producers of milk in the world; around 70 million rural households are engaged in professions linked to dairy. India is also the second largest exporter of bovine meat after Brazil. This sector provides a substantial income to farmers and supports the economy by generating enough demand in the rural and semi-urban regions. This animal husbandry sector comprising dairy and poultry is extremely valuable for farmer’s income security, and Covid-19 has the potential to disrupt this sector.

In developing countries such as India, where dairy farming is one of the most important sources of livelihood for 60 million rural households, 80 per cent of whom are landless, small and marginal farmers who depend on dairy for daily income, the crisis is extreme. Thus, even a small decline in the growth of the dairy sector significantly affects a large chunk of our population which are already vulnerable due to low income, poor savings, and lack of livelihood alternatives. Small production in multiple households leads to more reliance on efficient transportation for procurement. In addition to this, the Indian dairy sector is still dominated by the unorganized sector which handles more than 50 per cent of the marketable surplus. Milkman and vendors collect a small quantity of loose milk from different households and then supply it to urban consumers, roadside eateries, hotels, and sweetshops. Closure of shops and restrictions on transportation has ruthlessly disturbed this arrangement. Even in the formal sector out of the total milk processed 65 to 70 per cent is sold as liquid milk which is immediately vended after packing and only 30 per cent is processed into other dairy products like ghee, butter, cheese, curd, ice-cream, milk powder, etc. Thus, the formal sector also lacks sufficient infrastructure and storage facilities for processing and storing surplus milk after value addition.

Introduction

The state of Maharashtra now again reels under the scarcity of water. Geologically, major part of the state is covered by Deccan basaltic flows. This basaltic terrain, as such, has been labelled notorious as far as the availability of groundwater is concerned. Uncertain availability of groundwater in the terrain is due to heterogeneity in the nature of piles of basaltic flows which adversely affects the geohydrological characters of the rocks.

The area understudy is unfortunately, a part of basaltic terrain in which no storage structures like major dams or medium projects have been constructed across the existing rivers. Consequently, the irrigation in the area and domestic needs of the people solely depend on whatever water is available in the existing dug wells. The wells do not suffice the need of the people because the percolation of water in the wells is not adequate in major part.

Introduction

Sheep and goats have a vital economic importance in India, inhabitant in semi-arid region and mostly rose under harsh environmental conditions (high ambient temperature, scarcity of feed and water). The arid and semi-arid regions of India are drought prone due to low and uneven rainfall.  The vegetation of arid and semi-arid tract is more acute during summer when the quality of the pastures becomes vulnerable which in turn decreases the body condition score of animals and reproductive efficiency is being compromised (Maurya et al. 2009a & 2010).  The small ruminants are widely distributed in comparison of other domesticated species. These species of livestock is also a source of employment for marginal and land-less farmers particularly in the arid and semi-arid region of India. Most of the Indian farmers have limited resources and small ruminants production offers an opportunity to alleviate financial conditions and improve living standards.
