Jones and Ekman (1960) showed that ¹⁴⁴Ce is absorbed to a very small extent in the gut of the ruminant and suggested its use as a marker in digestibility trials. Huston and Ellis (1968) studied the affinity of radioactive cerium for feedstuffs and digesta particles in vitro experiments and found that cerium is rapidly absorbed onto and remained tenaciously bound to  digesta particles. Ellis and Huston (1968) tested radioactive cerium as a particulate flow marker in sheep with favourable results.

Experimental Procedure
Three Holstein bulls weighing 315, 239 and 305 kg and one Holstein steer weighing 327 kg are used. Twice daily, at 9.00 am and 9.00 pm, they are fed 3.4 kg of a balanced ration, meeting NRC requirements for normal growth and maintenance.

Limitation of Weende Method

The partition of carbohydrate into fiber (CF) and nitrogen free extract (NFE) is presumed to represent a separation of less digestible starch and sugars. However, in 20 to 30 percent feeds listed by Morrison, the NFE is less digestible than the CF. This comes about for several reasons, the most important of which is the CF method (successive boiling with dilute sulphuric acid and sodium hydroxide) does not recover all the fiber and large portions of fibrous constituents  are extracted into the NFE. The most  important of these fractions are lignin and hemicellulose are dissolved by both acid and alkali. The basic error of the NFE concept is the assumption that if constituents are soluble they are digestible. Lignin, the rigid component of wood, not only is indigestible but lowers the digestibility of substances with which it is associated.

Another portion of the indigestible part of NFE arises from an artifact in the calculation of faecal NFE, where it is presumed that faecal nitrogen is protein (N x 6.25). Actually, 80-90 percent faecal nitrogen is NPN and is composed of bacterial residue in which the ratio of organic matter to nitrogen is about 1:4. Thus, part of the faecal NFE arises by an underestimation of the organic matter associated with faecal nitrogen.

(Method of Bryant et al., 1959)

Strontium and barium are adsorbed on a cation-resin column, and  after a suitable gowth period, yttrium-90, the daughter of strontium-90, is selectively eluted. The yttrium-90 is then adsorbed on and eluted from a second cation-resin column and counted. The radiochemical yield is greater than 97% gravimetric measurement of the recovery of strontium and yttrium carriers is not required. The method, with modifications, is applicable to samples that contain 100 mg of iron or uranium.

Introduction

Meaning of Entrepreneur

The term “entrepreneur” is derived from the French verb entreprendre, which means “to undertake.” Historically, its meaning has evolved. In the early 16th century, it referred to individuals involved in engineering tasks like construction. By the 18th century, the term came to describe those engaged in economic activities. Over time, the concept of an entrepreneur shifted from someone participating in military ventures to someone actively involved in business and economic pursuits. Today, an entrepreneur is defined as an individual who innovates, organizes resources, and takes on risks to create new ventures or products with the goal of generating profits.

Richard Cantillon was the first who proposed the term “entrepreneur is an agent who buys factors of production at certain prices in order to combine them into a product with a view to selling it at uncertain prices in future.”

Introduction

A marketing plan is a strategic document that guides an organization in generating leads and engaging with target customers. It serves as a roadmap for how a company will approach the market, akin to a job description for the business. Every organization needs a well-crafted marketing plan that is tailored to its specific objectives, regularly updated, and aligned with customer demands. Companies with a solid marketing plan tend to be more successful and outperform their competitors compared to those without one.

The marketing plan outlines a strategy for growth by detailing how a company will attract and retain customers. It is an integral part of the overall business plan and lays the foundation for future market opportunities. A strong marketing plan focuses on customer needs and provides a clear roadmap for launching new products, expanding the customer base, and boosting the company’s profile. It includes essential elements such as business goals, mission, budget, and strategies. A well-designed marketing plan ensures effective promotion of products and services, helping businesses reach their target market and track success. Moreover, it should be flexible and adaptable to the evolving market landscape.

Abstract

The concept of functional foods has received significant media attention and, as a result, interest has focused on the need for research into the non- nutrient constituents of food plants. This has enabled market penetration of functional foods containing increased amounts of bioactive food compounds or physiologically active nutrients and non-nutrients within food that impart proven health benefits. Functional foods can take many forms. Some may be conventional foods with bioactive components that can now be identified and linked to positive health outcomes. Some may be fortified or enhanced foods, specifically created to reduce disease risk for a certain group of people. Numerous observational studies have shown that omega-3 fatty acids enriched diets are associated with a reduction of cardiovascular mortality, heart attack and sudden death. In several studies, a higher fish intake has been associated with decreased incidence of coronary artery disease (CAD) and cardiovascular mortality. A trial revealed that fish oil supplementation of 130 mg/kg of body weight each day decreased the number of stiff joints, duration of morning stiffness, pain and global arthritis activity. Many supplements contain active ingredients that have strong biological effects in the body. The bioavailability of nutrients within a given food is governed by the composition and microstructure of the food, commonly referred to as the food matrix. More specifically, numerous studies investigating the development of functional foods have shown that the interactions between nutrients and non-nutrients within the food matrix can be synergistic, additive, or neutralizing in nature. The preventive and curative effects of the functional foods on health concludes it to be integral components of established public health programs to reduce the risk of specific diseases.

All animals have a range of ambient environmental temperatures termed as thermo-neutral zone. This is the range of temperatures that are conducive to health, performance and well-being. The upper critical temperature is the point at which heat stress begins to affect the animal adversely. There are a number of climatic factors like temperature, humidity, wind speed and radiant energy/sunlight that influence the degree of heat stress. Heat is also produced by metabolism within the body, which includes maintenance, growth and production. Heat production is affected by body weight, species and breed, level of production, level of feed intake, feed quality and, to a lesser extent, by the amount of activity and exercise. Excluding temperature of the air ventilating the house, heat is also added from the roof and walls. Heat stress can be defined as the point where the animal cannot dissipate adequate quantity of heat to maintain body thermal balance. During the periods of heat stress, most of the productive energy is diverted to thermoregulatory adaptations that results into decreased weight gain, poor immunity, oxidative stress predisposing animals to various infectious diseases and high mortality rates. In order to characterize and quantify thermal comfort zones according to animal species, several thermal comfort indices or heat stress indices were developed.

The primary focus for livestock and poultry has been on heat stress indices to provide guidelines for environmental management and risk assessment for losses through linkages with physiological responses (Eigenberg et al., 2005) or performance (Baccari, 2001). The linkage is based on observations of a selected performance criterion (e.g., growth, milk or egg production) made concurrently with measures of the warm environment. These serve as inputs for the selected heat stress index and thus an empirical relationship can be developed which is termed as ?biological response function?. These indices recognize the ability of the animal to cope with environmental stressors by adjusting physiologically, behaviourally and immunologically to minimize adverse effects or even compensate for reduced growth and production performance during moderate environmental challenges. When the intensity and duration of potential stressors exceed thresholds, coupled with limited opportunity for recovery, animals are unable to cope and therefore are affected adversely. Nevertheless, the heat stress indices have served as useful surrogates for the complex interactions between the physical and biological components (Hahn et al., 2003).

Introduction

Digestion may be defined as the hydrolytic process carried out by various enzymes for breaking down complex food components such as proteins, fats and carbohydrates into simpler molecules like amino acids, fatty acids and monosaccharides, respectively. Whereas, absorption may be defined as the movement ofthese simple soluble digested food componentsalongwithvitamins, minerals and water from gastrointestinal track into the circulatory system.

The process of digestion starts from oral cavity (mouth) and ends at large intestineincluding tongue, teeth, jaws,secretions from salivaryglands (parotids, sub maxillary or submandibular and sublingual glands), pharynx, esophagus, stomach, small intestine and digestive enzymes secreted from pancreas and liver.

Digital dairy farming integrates IoT, artificial intelligence, machine learning, big-data analytics, cloud computing, sensors and automation to improve herd management. This chapter explains how wearable devices and monitoring systems support early disease detection, welfare assessment, milk-yield analysis and precision feeding. Automated milking, feeding and other operations reduce manual labour, improve consistency and lower operating costs. The architecture of smart dairy systems—including sensors, wireless communication and decision algorithms—is examined alongside environmental and economic benefits. Barriers include high initial investment, limited digital skills, poor rural connectivity and cybersecurity risks. Future developments may include AI-enabled autonomous dairy farms and interconnected, sustainable agricultural ecosystems.

Digitalization is transforming ice cream operations by connecting procurement, production, quality, cold chain, sales, distribution, finance, and management through integrated information systems. This chapter examines the transition from traditional manual operations to ERP-, AI-, IoT-, and data-driven management. It explains the costs of limited digitalization and the department-wise benefits of integrated systems, including better traceability, demand forecasting, inventory management, energy monitoring, cold-chain control, predictive maintenance, and profitability analysis. The chapter also explores artificial intelligence, business intelligence, IoT monitoring, and evidence from industry research. It emphasizes that technology alone is insufficient: standardized processes, accurate master data, user training, governance, and management discipline are essential for achieving measurable digital transformation.

Quantitative heat production estimation is necessary to  know the net energy of feeds and fodders. In the case of ruminants approximately 8 per cent of the gross energy consumed is lost as methane, therefore it becomes necessary to know this important loss in terms of methane energy so as to assess the metabolisable energy of any particular feed. In human subjects, heat production studies are conducted to know the effect of planes of nutrition on basal metabolism as affected by different environmental conditions.

In the important laboratories of world, heat production and methane production studies were conducted by respiration chamber (open circuit and closed circuit), since in our country respiration chamber has been installed at IVRI, Izatnagar, Bareilly (U.P.) India, therefore, this technique is mentioned in brief in this chapter. Indirect calorimetry involving the use of face mask and Douglas bag is followed at present in our country at NDRI, Karnal (India) so as to study the basal metabolic rate (BMR), heat production in human subjects and animals, Krishna (1973). Some laboratories in the country are interested to study respiratory quotient at different levels of feeding in human subjects and animals. The methods of estimation of RQ (respiratory quotient) is expressed in detail in this chapter.

Introduction

Disaster is defined as a serious disruption of the functioning of a community or a society causing widespread human, material, economic or environmental losses, which exceed the ability of the affected community or society to cope using its own resources (ISDR 2002).

Disaster in Global context - The impact of natural disasters in terms of human and economic losses has risen in recent years, society in general has become more vulnerable to natural disasters. Those usually most affected by natural and other disasters are the poor and socially disadvantaged groups in developing countries as they are least equipped to cope with them (IFRC 2001).

Introduction
In the past, the approach to disaster management was relief-focused and restricted to helping the area affected by the disaster. involves a continuous and integrated process of organizing, coordinating, and putting into action measures that are required or advantageous for preventing danger or threats, mitigating risk or its severity or consequences, building capacity through research and knowledge management, being ready to deal with any disaster, responding quickly to any situation that poses a threat to the community, determining the extent or severity of effects, evacuation, rescue and relief efforts, rehabilitation, and reconstruction.
Phases and Elements in Disaster Management
I. Pre-disaster phase: There are three components to the pre-disaster phase: preparedness, mitigation, and prevention.
II. The aftermath phase, encompassing response, recuperation, and restoration. All these components are connected by a structure of institutions and legislation.

Efforts to Mitigate Natural Disaster at National and Global Level

What is A ‘Disaster’?

It as ‘an event that has occurred unexpectedly with destructive consequences’ - (UNOCHA 2005). 
It as ‘a calamitous event resulting in loss of life, great human suffering and distress, and large scale material damage’ - (IFRC2005).
None of the international agencies take animals into account in their definitions

Introduction
There are always going to be natural disasters like cyclones, earthquakes, and floods. They are a component of our surroundings. Nonetheless, the amount of damage caused by natural disasters can be reduced if there is a reliable warning system in place
and the impacted population is ready. Thus, while reactive mechanisms constituted the majority of disaster management in the past, a change towards a more proactive, mitigation-based strategy has been gradually observed in the last several years.
The field of emergency and disaster management focuses on mitigating and preventing potential hazards. It is a field that deals with anticipating catastrophes, responding to them (e.g., emergency evacuation, quarantine, mass decontamination, etc.), and helping to rebuild society following natural or man-made disasters. Generally speaking, emergency management is the ongoing process through which all people— individuals, organizations, and communities—manage risks in an effort to lessen the effect of catastrophes that may arise from those risks. The perception of danger by individuals who are exposed influences the actions that are taken.
Definition
The word “disaster” comes from the French word “disaster.”
A disaster is a state brought on by natural factors in which there is a significant disruption of services and infrastructure that has an adverse effect on the environment, the economy, and human life.

A disaster is any event natural or manmade which creates an intense negative impact on people goods and services and or the environment and exceeds the affected community internal capability to respond prompting the need to seek outside assistance. In other words a disaster is a serious disturbance of a community or society interfere human resources losses and impacts on economically and environmentally or disaster means simply an event has unfortunate consequences on only on human but also on whole environment. Disaster can be two types’ Natural disaster and manmade disaster.

Introduction

A disaster is the result of an immediate situation or the result of a long, set process, which disrupts normal human life in its established social, traditional and economic system. This is due to the destruction of environment which is caused by extraordinary natural destructive phenomena or human-induced hazards resulting in human hardship and suffering beyond recovery unless external aid is brought in.

Climate change in particular global warming affect the health of the animals both directly and indirectly. Direct effects include temperature associated diseases like heat stroke and death and morbidity of animals during extreme weather conditions. Indirect effects include those deriving from attempt to adapt to changing environment or influence of climate on microbial populations, distribution of vector borne diseases, host resistance to infectious agents, feed and water shortages or food borne diseases. Among infectious diseases vector borne diseases and diseases caused by agents who have a stage in the environment are more likely to be affected than other diseases. The assessment of impact of climate change on animal diseases is challenging because there are several factors affecting the disease dynamics. But once the risk of potential diseases and their transmission routes are identified, the disease forecasts can be generated and control measures can be implemented to reduce the risk of such diseases.

4a. Intestinal Disorders
 
History of health claims
 
According to Bottazzi (1983) it was in 76 BC that the Roman historian Plinius recommended the use of fermented milk for treating gastroenteritis. Metchnikoff claimed that the intake of fermented milk containing Lactobacilli reduces the toxin producing bacteria, thereby increasing the longetivity of the host (Metchnikoff, 1908). Tissier (1905) showed that there was an increase in the Bifidobacteria in breast fed-infants, thus claiming that the administration of Bifidobacteria to infants suffering from diarrhea was very beneficial as they supersede the putrefactive bacteria that causes the disease. Intestinal beneficial microfloras are responsible to resist the disease (Bohnhoff et al., 1954).

The distribution systems are designed to ensure that processed fluid milk is stored and transported under optimal conditions, maintaining its quality and freshness until it reaches consumers. An effective distribution system for processed fluid milk involves careful planning and execution to guarantee timely delivery, quality preservation, and customer satisfaction. Given that milk is a highly perishable product, it requires meticulous handling and strict temperature control. Technology plays a crucial role in preserving its integrity throughout the supply chain. The use of technology reduces human error, increase the efficiency of distribution operations, and lower operational costs by preventing idle resources through coordinated logistics for both outbound and inbound trips.
To address the specific demands of manufacturing, packaging, distribution, and transportation, integrated business process automation solutions are implemented. These solutions include following features:
• Identify and define the most efficient delivery routes, reducing transportation costs and ensuring timely delivery.
• Scheduling and monitoring of delivery routes to maintain optimal delivery speeds, and manage loading and unloading processes so as to minimize exposure to adverse conditions. Automated solutions and tools help maintain the required temperature conditions throughout the entire supply chain.
• Verify and document supplier practices to ensure that all partners in the supply chain adhere to the agreed-upon temperature standards. Store the temperature-related data to help in auditing and analysis, and continuous improvement of the cold chain process.
• Shelf life and expiration date management is a critical component in  the storage and transport of dairy products. Proper management ensures that dairy products remain safe for consumption and retain their quality throughout the distribution chain.
