Introduction

Water is the most abundant compound in the body, and most of life’s essential processes take place in this aqueous environment. Although there is substantial variation, the total body water (TBW) of most domestic animals is approximately 60% of body weight (0.60 l/kg).Electrolytes are substances that exist as positive or negative charged particles in aqueous solution. The positively charged particles are “cations,” and the negatively charged particles are “anions”. The osmotic properties of a solute in solution are related to the number of particles in solution and not to its weight or its charge. One osmole of a non-dissociable substance is equal to its molecular weight in grams. One osmole of any substance that dissociates in solution into two or more particles is equal to the molecular weight in grams divided by the number of particles into which each molecule dissociates. Osmolarity is defined as the number of osmoles per l of final solution, whereas osmolality is the number of osmoles per kilogram of water. Although the expressions are similar, osmolality more correctly describes the osmotic properties as measured in the clinical laboratory.

Introduction

In every industry main running factors are as Manpower, machine, material and money.

Money is main big factor for capital expenses as well as operating expenses. Beside this other driving force are man power who installed and run the any industry based on their skill level.

Every organization has their own organization structure to manage industrial operation based on product variant like market milk, curd, paneer, buttermilk, butter & ghee, ice cream etc. Basic dairy plant organization structure is shown in below table and HR department mainly keep in mind to recruit them based on functional requirement, educational qualification, professional experience etc.

Based on above manpower requirement and product variants, processing cost to be worked out.

Recruitment of Manpower

Manpower is major key component of any industry/organization to run efficiently. The dairy industry, being one of the most vital sectors of the global agricultural economy, relies heavily on a skilled and efficient workforce to sustain its operations. Manpower’s involvement starts from milk production at farm level to processing and marketing of value-added dairy products, every stage to ensure quality, productivity and compliance with industry standards. Recruitment and training of manpower, therefore, play a primary role in addressing the challenges of modern dairy operation, including technological advancements, quality assurance, and sustainability.

Glycogen breakdown is known as glycogenolysis. This breakdown occurs in the cytoplasm of cells of the organs, wherein glycogen is stored. The end product of glycolysis is glucose in the liver, which is glucose-1-phosphate in skeletal muscles.
Glycogen is a polysaccharide synthesized from glucose monomers. Glycogen is stored in the cell instead of glucose because glucose requires more water, whereas glycogen can be stored with much less water. Most of the stored glycogen is in the liver (5% of body weight) and muscle (1 to 2 % of body weight). Muscle and liver glycogen undergo glycolysis for different purposes. Muscle glycogen provides energy for muscular activity, whereas liver glycogen helps to maintain the blood glucose level.
Glycogen contains many glucose residues (up to 120,000) linked by alpha 1-4 glycosidic bonds, forming a straight chain. Glycogen has branches at alpha 1-6 glycosidic bonds at every ten glucose residues. At the reducing end, the carbon one of glucose is free, whereas it is not accessible in the case of non-reducing ends.

Seed germination

It is defined as the emergence and development from the seed embryo, of those essential structures, for the kind of seed in question, indicates its ability to produce a normal plant under favourable conditions. The seedlings devoid of an essential structure; showing weak or unbalanced development; decay or damage affecting the normal development of seedling are not considered in calculating the germination percentage.

Rootstocks play an important role in the propagation of plants. It may modify form or stature, adapt a variety of a soil, fit in an incompatible climate, impart or resist disease to the scion, increase production, hasten maturity of crop, change the colour of the fruit, effect the flavour of the fruit, shorten life of the tree, increase the size of the fruit, develop vigour, effect salt tolerance and influence storage capacity.

Introduction
The development of the respiratory system in animals is a crucial process that begins early during embryogenesis. The respiratory system, responsible for gas exchange, develops from the endoderm of the early embryo, which is one of the three germ layers. Specifically, the respiratory tract develops as an outgrowth from the primitive gut tube (foregut). This process involves complex interactions of molecular signalling, tissue differentiation, and organ morphogenesis.
Key Stages of Respiratory System Development
1. Formation of the Respiratory Primordium
The respiratory system originates from the laryngotracheal groove, which appears on the ventral wall of the primitive foregut. This groove eventually forms the laryngotracheal tube, which serves as the foundation for the respiratory tract.
2. Division of the Foregut
The foregut is divided into two regions: The dorsal portion (oesophagus) for the digestive system. The ventral portion (laryngotracheal tube) for the respiratory system. This separation is achieved by the formation of the tracheoesophageal septum.
3. Development of the Trachea and Lung Buds
The laryngotracheal tube elongates and gives rise to the trachea) At its distal end, two lung buds form, which will develop into the bronchi and lungs. These lung buds expand, branch, and grow into the surrounding mesenchyme, a process called branching morphogenesis.

Animal welfare organizations are those organizations which are volunteered to help people to protect their animals. It is concerned with the health, safety and psychological wellness of animals. They have a deep understanding of needs of animals and thus help animals in distress. The types of stake holders depend on what type of animals are reared.

SYNOPSIS

Inspite of the fact that governments in various food summits and conferences have made commitments on food and nutrition security, presently more than a billion people are suffering from hunger and malnutrition worldwide. The food and nutrition policies need to be revisited and updated to address both man-made food scarcities and natural disasters of present and future to mitigate hunger and malnutrition.

Introduction

The basic concept of digital libraries is the sharing of information and resources globally for providing right and nascent information to the right user at the right time. It is the computing terminals having linkage to different sources of information in electronic or digital form. Digital library is a collection of information that is both digitalized and born in digital form, which offer capabilities beyond those of the agricultural and traditional libraries. Digital library is not only digitization of physical resources, but also thoughtful organization of electronic collection for better access.

Introduction
The urinary system comprises of two kidneys, two ureters, a urinary bladder, and a urethra) The latter is shared by the genital organs.
• The urinary system develops from the intermediate mesoderm
• Three different kidney systems are formed in vertebrates--pronephros, mesonephros, and metanephros.
Pronephros: - Forms a duct that empties into the cloaca- Pronephric tubules connect each body segment with the coelom (body cavity) Pronephric tubules never become functional in mammals
Mesonephros: - Pronephric duct becomes mesonephric duct Distal to the pronephric tubules appear mesonephric tubules that surround tufts of blood vessels (glomeruli), but no loop of Henle is formed Blood is transported to mesonephric tubules, filtrate is transported to the mesonephric duct and finally to the urogenital portion of the cloaca
Metanephros: - Metanephric bud (ureteric bud) Metanephric blastema
• Bud gives rise to the ureter, the pelvis of the kidney, and collecting tubules.
• Blastema gives rise to nephrons.
The internal structure of the kidney varies among species. It is determined by the number and size of calyces which branch from the renal pelvis. Each calyx forms the base of a renal lobe (renal pyramid). All mammalian kidneys begin as multipyramidal (multilobular) structures, but lobules fuse to varying degrees, depending upon the species. (Note, this multilobulation is maintained in the histological structures)

Productivity measures, such as rate of growth or reproduction have traditionally been used as indicators of biological functioning. If this is regarded as closely related to animal welfare, then high productivity should be evidence for a high state of welfare. In some cases, selection for production has pushed animals to the point where basic biological functioning and body maintenance is compromised. Therefore, Production measures are always misused.  Productivity of the group is a different measure than productivity of the individual. Such group overall is performing poorly but that productivity from a few outstanding individuals makes average productivity look high. Similarly specific individuals who are performing very poorly may be overlooked if average group performance is high. Although commercial organized dairy farms are very limited, but welfare issues are always there in both small and large farm. Some of the important issues in the organized farms are discussed below.

1.1 INTRODUCTION

India is the seventh largest country in the world in total geographical area and has second largest population next to China. Around 55 to 60 per cent of its population depend on agriculture and allied activities. Horticultural crops constitute a significant component of total agricultural production in the country. They require very intensive care in planting, carrying out different cultural operations, manipulating growth, harvesting, packing, transportation, marketing, storage and processing.

1.2 AGRICULTURE

The term agriculture broadly refers to the technology of raising plants and animals. Agriculture is the science, art or practice of cultivating soil, producing crops and raising livestock in varying degree of proportion followed by marketing. In other words, it is the activity of man to produce three basic needs of human being, i.e., food, fuel and fibre (3F) by using terrestrial resources optimally. The term agriculture is derived from two Latin words ager meaning field or land and cultura meaning cultivation or growing.

The major components of foods are the protein, carbohydrates and fat. The spoilage of foods containing fats includes the deterioration of the fatty components; the principal difficulties found in their preservation are in the development of rancidity. The spoilage of fats and oils has received much attention and substantial progress has been made in their preservation. One of the major causes of food deterioration is the chemical oxidation of unsaturated fatty acids in the lipids present in all foods. These fats are present in fat deposits and in cell membranes. End products of lipids oxidation, mainly aldehydes and ketones, contribute to the rancid off flavour and odours in the foods.

Fatty acids in food occur in the form of esters with the alcohol. The predominant esters are triacylglycerols accompanied by minor amounts of mono- and diacylglycerols and free fatty acids. The unsaturated bonds present in all fats and oils represent active sites that can react with oxygen. This reaction leads to formation of primary, secondary, and tertiary oxidation products that may make the fat or fat containing food unsuitable for consumption. Other consequences of oxidation include discolouration; changes in the texture, flavour and taste; and loss of nutritional value due to the destruction of essential fatty acids as well vitamins. Unsaturated fatty acids are subject to oxidation at their double bonds. In the presence of suitable catalysts, or in contact with lipooxidase enzymes, long chained unsaturated fatty acids may be fragmented to short chained fatty acids. The cleavage usually involves an intermediate peroxide formation. Many chemicals compounds aid in food preservation to protect the nutrients, flavour and texture, and storage stability of food stuff for longer period.

The duck environment usually involves the presence of water bodies (man-made or natural) which may enhance the co-mingling of free-living waterfowl species with the domestic flock promote disease transmission. Besides, environmental conditions also influence disease manifestation in ducks. The most of the viral diseases in ducks are contagious and transmitted very easily among the healthy birds in contact. The infectious viral diseases most commonly seen in domestic waterfowl species includes duck plaque, duck viral hepatitis, avian influenza, musky duck parvo virus infections, duck pox etc. These viral diseases cause great economic loss to the poultry industry due to high mortality and morbidity rate.
