Introduction

Climate-smart small ruminant production is an approach for transforming and reorienting the small ruminant production under the new realities of climate change. The main objective of climate-smart small ruminant production is to make the production sustainable for national food security, enhancement of resilience, and reduction of greenhouse gasses emission. Climate-smart agriculture is that, which increases the sustainable productivity, enhances resilience, reduce greenhouse gasses (GHG) and boost the achievements of national food security and development goals (FAO, 2013). In India, most of the rural communities earn their livelihood on smallholder livestock production system and they are very much vulnerable to climate change. Therefore, the need of the hour is to address the impact of climate change both in terms of adaptation as well as mitigation perspective (Vemeulen et al., 2013). The increase in population, the higher income, urbanization, and change in dietary preference leading to increased demand for animal products that pressurizing for higher productivity of livestock (Delgado et al., 1999; Thronton et al., 2007).

The mutton production in our country was 399 million Kg in 2012 which will be around 537 million Kg by 2020, and 840 million Kg in 2030 and 1317 million Kg in 2050. However, the requirement for mutton would be 813 million Kg by 2020, 986 million Kg by 2030 and 1408 million Kg in 2050. Similarly, the wool production in the country is 44.7 million Kg in present time (2011-2012), which have to be increased 150, 180 and 200 million Kg in 2020, 2030 and 2050, respectively. But the harsh climatic condition, shrinkage grazing resources, increase in cultivation and industrialization and decline interest of new generation for small ruminant rearing; making a question mark to meet the future demand in the current production trend. The scarcity of resources, impact of climate change and increase demand for mutton has made the traditional coping mechanism less effective (Sidahmed, 2008). Therefore, we need climate-smart sheep and goat production option that can achieve the triple win scenario of increasing productivity, adapting and building resilience to climate change through a reduction of greenhouse gas (GHG) emission (FAO, 2013; Shikuku et al., 2016).

Cloud computing and Edge AI provide complementary infrastructure for intelligent livestock management. Cloud platforms offer scalable storage, centralized analytics, model training and integration of data from sensors, cameras, automated feeders and farm-information systems. Edge AI processes information close to the farm, reducing latency, bandwidth consumption and response time. This chapter explains their architectures, workflows and applications in dairy, poultry, swine and small-ruminant production. Uses include disease detection, estrus prediction, behavioural monitoring, feeding and environmental control. Hybrid cloud-edge systems balance centralized intelligence with local autonomy. Challenges involving connectivity, interoperability, cybersecurity, cost, model reliability and ethical animal surveillance are also critically examined.

Dried Cocoa Bean have chemical composition as: The shell (testa) represents 10-14% dry weight of the cocoa bean, while the kernel or cotyledon is made up of most of the remaining 86-90%. The cotyledon confers characteristic flavours and aromas of chocolate and is composed of two types of parenchyma storage cells.

Before processing, the quality ofbeans is evaluated for the following indicators:

1. Degree of fermentation
2. Moisture content (maximum 6%)
3. Number of defects
4. Number of broken beans
5. Bean count (number per 100 g)

Cocoa butter, also called the obroma oil, is a pale-yellow, edible fat extracted from the cocoa bean. It is used to make chocolate, as well as some ointments, toiletries, and pharmaceuticals. Cocoa butter has a cocoa flavor and aroma. Its melting point is just below human body temperature. Cocoa butter that has been refined by neutralization with an alkaline solution and decoloured with for example bentonite, activated carbon etc. Subsequent deodorization can also be applied. The type of process used may affect the quality of the cocoa butter. For example, a too high deodorization temperature or a too severe alkalization can completely alter its setting (solidification) characteristics. High-quality raw materials are needed to make the best quality cocoa butter. The other important factors for high quality are the origin of the beans and the processing conditions used. Press cocoa butter, which is most commonly used in the chocolate industry, is only filtered and (partly) deodorized to obtain the desired flavour. Cocoa butter contains a high proportion of saturated fats as well as monounsaturated oleic acid, which typically occurs in each triglyceride.

Introduction

Botanical name of cocoa is Theobroma cacao and family is Malvaceae. The cocoa bean, also cacao bean or simply cocoa or cacao, is the dried and fully fermented fatty seed of Theobroma cacao, from which cocoa solids and cocoa butter are extracted. Cocoa flavour is the most distinct feature of chocolate, thus cocoa beans are the basis of chocolate. Dried cocoa beans are usually processed into cocoa butter, which contains fat between 56% and 58%, made up of a mixture of triglycerides. Cocoa butter with this composition is good for making chocolate and has favourable hardness and a melting point of body temperature. Theobroma cacao originated from the Jungle of the Amazon in Brazil. Theobroma cacao consists of two subspecies: the Cacao, a subspecies known as the Criollo, which can be found in Central and South America, and spharocarpum, which is also called theForastero. The Criollo has superior and fine flavour. The pods are red and the beans have no color. Forastero has a green pod

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.

Cold plasma technology represents an innovative non-thermal approach for improving food safety while minimizing undesirable changes associated with conventional heat treatments. This chapter introduces the fundamental principles of cold plasma and explains how reactive species generated during plasma treatment can contribute to microbial inactivation and food decontamination. It examines major plasma-generation methods, including dielectric barrier discharge, corona discharge and microwave plasma systems. The chapter highlights the potential of cold plasma for preserving nutritional and sensory characteristics while reducing microbial hazards. It also considers technological challenges such as treatment uniformity, interactions between plasma and food matrices and the need for process optimization and regulatory validation for wider industrial adoption.

Introduction
Similar to the procurement of raw materials in a factory, milk collection is one of the initial and essential steps for a milk processing or marketing company. A successful milk collection system combines efficient route planning, quality control, and effective farmer engagement. By prioritizing technology integration, cold chain management, and regulatory compliance, dairy companies can establish a reliable and sustainable milk procurement system that meets both operational and quality standards.
India dairy sector depends on smallholder individual milk producers, each contributing between one to a few litres of milk per day. Typically, milk production takes place in rural areas, while the demand is concentrated in urban centres. However, rural producers often face significant marketing challenges due to the dispersed nature of milk production, scattered settlements, and inadequate supply infrastructure. Therefore, milk needs to be collected, transported, and marketed from villages to cities to ensure profitable returns for producers. Milk is usually collected from producers at designated collection points in rural areas, which serve a large number of small suppliers. This approach minimizes the need for individual chilling and storage facilities. Collection points should follow the same hygiene standards as dairy processing facilities. Milk should arrive at a chilling station within four hours of milking, especially in warmer climates. There, it must be quickly cooled to below 4°C to preserve its quality. Bulk milk coolers of required capacity are installed for the chilling and storage of milk at low temperature till it is transported to the processing plant.

2.1. INTRODUCTION

The purpose of collecting data is to collect evidence for reaching a sound and clear solution to a problem. In this chapter we will study the sources of data, mode of data collection and its techniques.

Sources and Types of Data

Statistical data can be obtained from two sources:

Primary and

Secondary

Steps in the Estimation of Trace Elements
Estimation of trace elements in feeds and fodders and other biological materials involves the following steps :

    1.    Production of an acidic solution of the inorganic elements in the biological samples after removal of the organic matter by dry ashing or wet oxidation.

    2.    Removal or masking of interfering substances.

    3.    Determination of the selected elements, usually by using colorimetry.

Results of trace elements determinations are expressed as parts per million (ppm), mg/kg or µg/g dry matter.

Introduction Colostrum feeding • Colostrum is rich source of gamma globulins (antibodies), vitamins and minerals • Colostrum Temp.: 99ºF-102ºF • Colostrum feeding: first 3-5 days. • Whole milk: after 5 days • Feed the total amount of milk at 3 or 4 equal intervals up to the age of 7 days and then twice daily • Quantity of colostrum: 10 % of body weight. • Overfeeding: calf scour/diarrhea. • Around 0.5% of a cow’s yearly milk production is made up of colostrum. • After birth, the amount of immunoglobulins that can be absorbed from colostrum drops by 1/3 as soon as 6 hours, by 2/3 after 12 hours, and an intestinal barrier forms after 24 hours. • Colostrum must be given in sufficient amounts to the newborn calf because during the first 24 hours after parturition, the permeability of the stomach and the concentration of immunoglobulins drop sharply. • Cow colostrum must meet minimum requirements for both immunological and bacteriological characteristics:

Celite Column Chromatography
(Method of Wiseman and Irvin, 1957)
Principle

Celite columns with an internal indicator have been developed for the quantitative separation of silage and rumen volatile fatty acids ranging from butyric to succinic. The aqueous phase employs minimal amounts of sulphuric acid to prevent retention of organic acids, sugar is added to the phase to increase elution resistance. Aqueous samples, 2 ml or less are added directly to a dry column cap. Eluting solvents are mixtures of acetone and petroleum ether. Single zone collections make possible a reduced number of titrations with increased accuracy. The column permits fairly wide separations of lactic acids, often difficult on silicic acid columns.

The method employs celite with alphamine red R as an internal indicator. A distinctive feature is the use of concentrated sugar solution as the stationary phase to resist leaching action of solvents.

1.1. Introduction

A typical dairy farm consist of different classes of dairy animals like calf, heifer, breeding heifer, pregnant, milch and dry animals and bull. The systems of management for the different classes are not same. They need some routine as well as periodical farm practices, some of which are common for all categories of animals (i.e., identification, dehorning, grooming etc.), while some categories need special farm operations (e.g., castration in males, milking etc.). Also there is need of routine disinfection of animal sheds and farm premises to prevent and control occurrence of diseases and maintaining the animals healthy. Further for proper execution of all these operations there is need of keeping farm records.  Keeping in view the above points, this section deals with some important farm management practices.

The response of any living cell to a xenobiotic (including antibacterial agent) is significantly affected by the prevailing local environmental conditions. In case of bacterial infection, it may include the presence of other microbes, no matter commensal or pathogenic, or biochemical alterations at that particular site of bacterial infection in host. All these host and bacterial factors play a critical role in the evolutionary responses of bacteria but usually go unconsidered while determining the microbial sensitivity to a particular antibiotic in a clinical setting. These also include the direct and indirect interspecies interactions that can affect the responses of individual bacterial species and surviving microbial communities to a particular antibiotic therapy. These interactions may significantly alter the qualitative and quantitative responses, potential phenotypic changes and the final trajectory of evolution of antimicrobial resistance. Due acknowledgement and plausible interpretation to these interactions may help to reduce the upsurge in AMR and its associated morbidity and fatality and pave path to more proficient clinical success.

The factors participating in drug- microbe interaction can be classified into two broad groups: host factors and microbial factors. The environmental milieu of the interaction is chiefly regulated by the gut microbiota with stressors causing deflections. The gastrointestinal bacteria amend host mental and physiological cadence via microbial metabolites such as butyrate, polyphenolic antioxidants, vitamins, and amines, affecting the overall ready perception and active rebuke to a stimulus. Lifestyle stressors such as fluctuating sleep and erratic eating patterns (western diet) disturb the host circadian system along with the gut microbiome. The overall impact is impaired detoxification (decreased conjugation of bile acids or increased production of hydrogen sulphide), substrate oxidation and energy regulation (reduced butyrate production) in the host affecting the overall health and productivity.

Activation : The process of causing a substance to become artificially radioactive by subjecting it to bombardment by neutrons or other particles.

Activation Analysis : Any analytical procedure permitting the detection and measurement of trace quantities of elements following their exposure to a flux of neutrons.

Activity :  The strength of a radioactive source. In absolute units, it relates to the number of radioactive atoms decaying per unit of time. It is also a synonym for radioactivity. Absolute activity is usually expressed in curies or millicuries.

Alpha Particle : A particle which is identical to the helium nucleus, consisting of two protons and two neutrons. It carries a positive charge of 2.

Alpha Rays: A stream of helium nuclei. The helium nucleus has a mass number of 4 and an atomic number of 2. If consists of two protons and two neutrons.

It is emphasizing the systematic approach required for the successful planning and funding of projects:
Components of Project Formulation
1. Needs Analysis: Identifying and defining the needs that the project intends to address, typically involving stakeholder consultation and market analysis. This process involves systematically gathering and analyzing data about a community, a group, or a market to identify both the current conditions and the gaps between these conditions and desired outcomes. Effective needs assessment aids in designing projects that are relevant, targeted, and likely to produce significant impact. Here’s a more detailed exploration of how needs assessment is integral to project formulation:
Key Steps in Conducting a Needs Assessment
• Stakeholder Identification: Early in the project formulation, identify all relevant stakeholders, including direct beneficiaries, community leaders, funders, and other affected parties. Understanding who will be impacted by the project helps in targeting the needs assessment process more effectively.
• Data Collection: Utilize various methods such as surveys, interviews, focus groups, and field observations to gather comprehensive data about the current state and deficiencies experienced by stakeholders. This might involve looking at socioeconomic data, environmental conditions, or specific community challenges.
• Gap Analysis: Analyze the data to identify gaps between the current state and the desired outcomes. This analysis helps pinpoint the specific areas where interventions are needed.formulation: 

As an engine requires fuel to run, similarly the animal body requires food to run its vital activities. Food, after its digestion, absorption and oxidation, provides energy to the body. The energy thus obtained is utilized by the animal for maintenance, growth, reproduction and production. Hence, a good quality of food should be provided to the animal so that it may fulfil all the requirements of the animal. Food contains water, carbohydrates fats, proteins, vitamins and minerals which are essential constituents of the body and indispensable for life. Water being an essential constituent of protoplasm carries out many other important and inevitable functions in the body. Water helps the body absorb nutrients from the food and throw out wastes from body in the form of sweat and urine. Carbohydrates, fats, and proteins provide energy to the body. Fat provides 2.25 times more energy than carbohydrate and proteins. Besides providing energy, proteins are also essential for body building, growth and repair of wear and tear of the body tissues. Vitamins protect the body against diseases and help in keeping eyes, gums, skin, teeth and bones healthy. Vitamins are required by the body in small quantities. Vitamins are essential for normal growth, health and reproduction. Prolonged deficiency of vitamins causes characteristic diseases. Minerals required in small quantities are essential for normal growth of body and maintaining good health. Skeleton system of the body contains principally Calcium and Phosphorus with small amount of Magnesium.

Introduction

Until the 20thcentury, bacterial infections were the number one cause of human death. In the 1940s, antibiotics became the lifelines for treating serious infections that saved millions of lives. Despite the advantages derived from the use of antibiotics, resistance to these drugs emerged. Unfortunately, resistance to most antibiotics emerged in time-course even for the most powerful antibiotics developed.Resistance to antibiotics is a challenge to the scientific community in keeping up the pace of antibiotic discovery.World Economic Forum’s Global Risks Reporthas listed antibiotic resistance as one of the greatest threats (WEF, 2020).United Nations (UN) has warned that drug-resistant diseases could account for 10 million deaths each year by 2050. By 2030, antimicrobial resistance (AMR) could likelylead up to 24 million people into extreme poverty(IACG,2019). Currently, at least 7,00,000 people die each year due to drug-resistant diseases (IACG,2019). The emergence and widespread of antibiotic-resistant organisms is a global challenge and needs a multi-dimensional approach to address the fundamental issues to minimize drug-resistance.The Antibiotic Resistance Genes Database (ARDB) contains a repository of around 23,000 antibiotic resistance gene or protein sequences conferring resistance against over 240 antibiotics (ARDB). Computational Biology (Bioinformatics) has become one of the important tools in studying antimicrobial resistance. It employs a range of computation techniques to make predictions about the biological phenomenon.

Abstract

Food dehydration is an oldest method to increase the shelf life of food by reducing the water activity. A dried food product provides advantages of increased shelf life and reduced cost due to decreased weight as well as transportation. However, there is a decrease in product quality due to inadequate control on drying process parameters such as drying temperature and moisture removal together with change in thermo-physical properties of food. Computational modeling and simulations can provide a unique insight on the drying parameters that influences the product quality, and optimize the process conditions which are difficult by experimental analysis. Moreover, the computational techniques are advantageous over experimental optimization methods by minimizing the time and cost. This chapter reviews different computational modeling techniques such as, finite element modeling, finite volume and finite difference methods for modeling of food dehydration process. Also, this chapter describes the application of modeling techniques for determining the influence of shrinkage and porosity during dehydration.

Milk may be concentrated as a necessary initial step in drying operation or as concentrating step in the manufacture of sweetened condensed milk or evaporated milk or the preparation of infant formulae. In order to preserve the milk constituents in a concentrated form, condensed milk/concentrated milk is manufactured from whole skim milk by removing or evaporating part of the water under vacuum. But this form of milk still has limited shelf life. Attempts to prolong the shelf life of this product have been made through the addition of bacterial growth inhibitor like sugar (sweetened condensed milk) or by heat processing (evaporated milk) to destroy the microorganisms.

Concentrated milk industry is an important segment of dairy industry. It plays an important role in the economy of industry. It serves as a balanced economy. It utilizes surplus milk in the flush season. It utilizes abundant milk production in certain localized area. It makes use of surplus milk below excellent grade. By either concentrating or drying less space is needed to store and it becomes less bulky and therefore it can be transported to any part of the world. The keeping quality of milk is increased. The concentrated products give considerable saving in the cost of packaging, storage and transportation. Milk concentrates can be easily reconstituted with required amount of water corresponding to that removed by evaporation to yield a product having normal consistency of milk. It is estimated that nearly two per cent of the world’s milk production is converted into different types of condensed or concentrated milks.

Brief history and developments: The present day concept of preservation of milk by concentration and by application of heat had the beginning with the pioneering work of French man Nicholas Appert around 1793. Gail Bordon of USA was first to commercially exploit the method of concentration of milk under vacuum. He was awarded U.S. Patent in the year 1856 for processing milk in a semi-fluid state after evaporating under vacuum. Commercial production of sweetened condensed milk by Gail Bordon started in 1856.
