Introduction

It has been proved that libraries play a crucial role in education. Libraries have been collecting, preserving, and organizing knowledge since time immemorial. In the age of virtual information, libraries have been reinventing themselves as accessible and engaging learning spaces. Libraries existed in India during the ancient and medieval periods. The library is the primary requirement of the university. University libraries have a paramount role in developing university education in the country. The present chapter highlights the historical development of libraries, committees, and commissions on university libraries in India.

Introduction

India has cemented its position as the global leader in milk production for 2023-24, contributing a staggering 230.58 million tonnes, or 25% of the world’s total supply. This achievement reflects an annual growth rate of 4%, driven by a vast network of small-scale farmers who manage one or two milch animals each. Despite their limited productivity, these farmers collectively power the nation’s dairy industry. Before the transformative Operation Flood, the sector was fragmented, dominated by middlemen, and poorly linked to urban demand. The initiative revolutionized the industry, introducing cooperative, private, and state driven organizations that established a seamless system for milk procurement, processing, and marketing. Today, thousands of dairy factories across the country transform raw milk into value-added products to meet India’s immense demand, with rural households allocating 15.51% of their food budget to dairy and urban households spending an even higher 18.19%. Coordinating milk collection from millions of scattered producers and delivering it to processing facilities is a monumental task, yet this streamlined system ensures that India’s dairy sector continues to thrive and satisfy its growing consumer base. India’s dairy export performance in 2023-24 was nothing short of “legendairy,” shipping 63,738.47 metric tonnes of dairy delights worth $272.64 million to fans in the UAE, Saudi Arabia, USA, Singapore, and Bhutan. Butter, ghee, and dairy spreads took the spotlight with $43.65 million in exports (8,106.54 MT) to destinations like Saudi Arabia, Bahrain, and Qatar, spreading Indian flavor worldwide. Cheese exports were equally impressive, with 9,262.63 MT worth $46.84 million making their way to the UAE, USA, and Bhutan clearly, everyone loves a slice of India.

Reproductive Organs of Fowl and Formation of Egg

The reproductive system of a hen is a fascinating and intricate setup designed to produce one of nature’s most perfect foods-the egg. Understanding this system requires a look into its two primary components: the ovary and the oviduct.

The Ovary

The ovary is where the magic begins. A hen typically has two ovaries, but in most cases, only the left ovary develops fully and remains functional. The right ovary, although present, becomes rudimentary and non-functional. The left ovary is responsible for the formation of ova, the initial stage of the egg.

Inside the ovary of a hen are approximately 2000 visible yolk-filled ova. These ova are the potential eggs, each waiting to be developed and released. As a hen matures, these ova progress through various stages of development. The transformation from an immature pullet, which has a small, undeveloped oviduct weighing about 1.1 grams, to a mature pullet ready to lay eggs, involves significant changes. By the time a pullet lays her first egg, her oviduct has grown to weigh around 77.2 grams.

Introduction

The climatic elements such as solar radiation, temperature, precipitation, humidity, evaporation, evapotranspiration and wind velocity affect growth and development of saplings. These climatic factors are not favourable for successful propagation of various horticultural crops in arid region. The main climatic features of Indian hot arid agro-ecosystem is high wind speed, sand storm and high temperature during summers up to 48-50oC  and during winter season temperature falls to the 2-3^°C, low atmospheric humidity i.e. 20-30% during maximum period of the year. Moreover the relative humidity goes down to below 10 per cent during summer months.

Vegetable seed drying is the most critical stage for any shop floor activities. Only properly dried seed will be taken for processing and all the other activities from seed receipt to storage. Seed producers harvest the seed which will have more moisture than packaged seed. For example onion seed harvested when its moisture at 60% but eventually dried to 10-12% for safe storage and packaging. Seed drying is highly skilled and specialized activity without affecting the seed quality. Proper drying procedures are vital for storage and field performance of seed lots. Drying prevents germination of the seed, the growth of bacteria and mould and it reduces the conditions for development of insects. The moisture content of a seed is influenced by the humidity of the air because they are very hygroscopic in nature. The more moisture in the air, the higher the moisture content of the product. If seed are harvested during warm, humid weather, the moisture content of the seed will be high because the relative humidity of the air is high as well. It is necessary to dry the seed before it can be stored safely. The method of drying depends on the local conditions (climate, season, volume of the seed, type of seed etc)

11.1 Biodiesel Chemistry

Biodiesel is a mixture of methyl esters of long chain fatty acids like lauric, palmitic, stearic, oleic and so on. It is produced by the transesterification of animal fats and vegetable oils – all of which belong to a group of organic esters called triglycerides. Typical examples are rape/canola oil, soyabean oil, sunflower oil, palm oil and its derivatives, etc. from vegetable sources, beef and sheep tallow and poultry oil from animal sources and also from used cooking oil. The chemistry is basically the same irrespective of the feedstock. The chemistry of biodiesel is given in Fig. 11.1.

Developing a nutraceutical or functional food is becoming mandatory as looking at the current nutritional status of the population over the world. Nutraceutical foods are proven to cause several health benefits to people. Hence the basic aim behind developing the nutraceutical chocolate bar was to fulfill the nutritional demands and provide some additional benefits to people. The product mainly contains two key ingredients that are, Drumstick (Morings oleifera) which has the most qualities to call a Superfood” and Quinoa (Chenopodium quinoa) which is referred to as “Mother of all grains”.

Introduction

Plant pathogens include fungi, bacteria, viruses, viroids, phytoplasma, and nematodes.

They have evolved different strategies for invading, feeding on, and reproducing inside plants.

Biotrophic pathogens require living tissue to grow and reproduce.

Necrotic pathogens kill host tissue at the onset of infection and feed on the dead tissue.

Viruses generally require living tissue for survival.

Introduction

The applied aspect of tree improvement consists of the development of improved trees followed by the mass production of the improved stock. No programme will be successful until both have been achieved. Too often, the improvement of forest trees is obtained without sufficient concern about how the improved material is to be reproduced and used on an operational scale. The better trees can be regenerated through seed or by vegetative propagation. All tree improvement programmes must have seed production at some stage of their development if continued gains are to be achieved. This is even true for the programmes using vegetative propagules for large-scale operations of planting; seed is needed for the development of outstanding trees, from which, vegetative propagation can be achieved.

Introduction

Though India is a highest producer of milk in the world, only 15 to 20 per cent of the milk is marketed through organized sector comprised of cooperative societies, public and private processing plants. Bulk marketing is limited to processing plants and cooperative societies. In contrast to Indian situation, most of the milk in developed world is consumed in different processed forms. It is something very general to India where overall food markets for processed foods are generally low and same is the case with milk. By all estimates about 75 per cent of the milk purchased by the consumer as liquid milk whether raw or processed. The share of pasteurized milk is only 10 per cent but the demand is increasing at the rate of 15 percent per annum. One fourth of the milk production is processed in the unorganized sector transforming into products like, sweets. Khoa, paneer, curd, lassi, etc. There are small scale milk product manufacturing units which fall in the category of semi-organized sector comprised of creameries, ice-cream units which are manufacturing the similar products as produced by the composite milk plants in the organized sector. They generally serve the local markets but have the important share in processing of milk as well as meeting the consumers specific demands. The organized sector comprised of mainly dairy plants, procures surplus milk through Milk Producers Cooperative Societies and generally follows the HACCP standards leading to quality of the products, whereas unorganized sector is composed of milk vendors, contractors, halwaies and creameries, collect milk from producers and sell either as raw milk or manufactured milk products or both.

Incubation is a critical process in poultry farming, involving the hatching of fertile eggs to produce chicks. This process can be carried out by natural or artificial means. Natural incubation involves placing eggs under a broody hen or duck, allowing the mother bird to provide the necessary warmth and conditions for hatching. In contrast, artificial incubation uses machines called incubators to create the ideal environment for the eggs to hatch. The incubation period, which varies among different poultry species, remains consistent within the same species regardless of whether natural or artificial methods are used.

Incubation

• It is simply the production of chicks by hatching fertile eggs either by natural or artificial means.

Introduction
The mammalian embryos are subdivided into two groups namely domestic animals where extraembryonic membranes form by folding process, and primates where blastocyst implants very soon after it enters the uterus and extra embryonic membranes forms after implantations. The major function of fetal membranes is to provide nutrients to developing fetus, protection, synthesis of enzymes and hormones and caring of fetal waste products. It is consisted of yolk sac, amnion, allantoic and trophoblast or chorion. The trophoblast is the single most important tissue of fetal membranes which has potential role in absorbing, transmitting and handling nutritive and waste products.
Yolk sac
It is a primitive structure. Develops early in the embryonic period from the entoderm which disappears after short period of time in ruminants. The uterine milk, secreted by the endometrial glands, is absorbed by the blastocyst along with yolk sac to provide nutrition to early embryo. Before forming other embryonic membranes yolk sac performs limited functions whose role is limited during mid and late gestation.
Amnion
It is an ectodermic vesicle that arises from an out folding of the chorion which is a double walled sac that completely surrounds the fetus except at the umbilical ring. The inner layer of this double-walled sac is the “true amnion” and the outer layer is the “false amnion” amnion chorion. Like yolk sac, the amnion chorion also lasts for shorter period.The amniotic fluid is clear, colorless and mucous in nature. Source of amniotic fluid: In early to mid-gestation, it is probably from the amniotic epithelium and from fetal urine as the fluid is quite watery. As gestation advances, the allantoic fluid increase in volume while the amniotic fluid volume remains fairly static but

These concepts are presented in the context of improving quality, traceability, market access and international competitiveness of Indian floricultural products.

ABSTRACT

Documenting the traditional knowledge system for technology development considers as the first step towards a sustainable agriculture. A study was undertaken in some villages of operational area of KVK, Nalanda district to investigate and document the traditional knowledge system of dairy farmers in the area of Breeding, Feeding, Health care and Management. The findings revealed the materials and practices related to animal husbandry from the study area. The majors among them were like use of Eucalyptus leaves in controlling Haemorrhagic septicemia (Gala ghotu), allowing animal to remain stand in mud for few hours, spread out tobacco leaf power on the infected part of FMD disease, applying brine solution on the animal’s buttock for the treatment of mastitis, feeding banana stem juice in order to controlling diarrohea in dairy animals. Papaya fruits fed to the cattle increases fertility in them, spraying of chhoa for controlling termites, incorporation of tobacco leaf, betel leaf and curry leaf enhances the shelf life of ghee at least by 2 months, use of Eucalyptus leaves in controlling Pneumonia in cattle.

Introduction

Libraries are universally recognized as important social institutions for diffusion of knowledge and information. The modern and highly equipped libraries are found in the universities since they are the centers of higher education, training and research. The universities libraries are essential to achieve the objective of university education and research.

Abstract

Indiscriminate and intuitive applications of the synthetic pesticides have adversely affected the ecological balance, resulting in pest resurgence, development of resistance in the pest species and environmental pollution. Biocontrol agents are now available to contain effectively diverse diseases and pests of various major field, fruit and vegetable crops with the result their demand in market has enhanced several folds but low production and scarce availability is a major constraint in their large scale adoption by farmers. While as now protocols for mass production of a number of biocontrol agents have been standardised and simplified, these can now be adopted by the unemployed educated youths to start entrepreneurship for self employment. In order to empower and improve the women farmers’ productivity, they need to have proper farm training and capacity building programs to compete various challenges in their rural livelihood and mass production of bio-control agents is an emerging enterprise with commercial potential. The Indian bio-pesticide market stands at over US$127 million (7-8% of the global market) and is expected to triple by FY20. The research efforts at the ICAR institutes and SAUs have been targeted to relieve women of the drudgery by providing technologies, time and labour saving tools with good market linkage. Women self help group with proper training can start their own bio-pesticides units for which finance with subsidy is available.

Quinoa (Chenopodium quinoa Willd.) is a part of “Chenopodiaceae” family. Up to 250 species of Chenopodium have been identified to date. Quinoa is a South American grain that has been farmed in the Andes for thousands of years, particularly in Peru and Bolivia. It is considered as a sacred plant because of its abundance in protein and essential amino acids (Jancurova et al., 2009). Quinoa is distinguished by its excellent adaptability to a diverse variety of land and environmental variables. Both leaves as well as the grains are considered as the edible parts. However, the quinoa grains have been extensively studied and economically explored (Rocha, 2008).

Introduction

Test of pollen viability (extent of pollen viability) is important in pollination experiments to ensure fertility/seed setting. It is also important in monitoring state of pollens during storage in ecological/ taxonomic studies as well as during research on pollen biochemistry, genetics, stigma interactions, and incompatibility studies. Pollen viability refers to the ability of pollen to accomplish post-pollination events to achieve fertilization. Pollen viability test has gained importance particularly in plant breeding and hybrid seed production experiments/ practices. In this chapter, you will be acquainted with the basics of pollen viability test. However, for more professional knowledge on the topic readers are suggested to refer specialized books.

Pollen Viability Test

It is important to know the extent of viability of pollens used in pollination experiment, in finding fertility of a plant of interest, to monitor state of pollen on storage, in ecological/taxonomic studies, as well as in research on biochemistry, genetics, stigma interaction, incompatibility assay, etc. of pollen. Several pollen viability tests have been developed time-to-time. It is recommended to initially use different tests for a given pollen type to find out the most appropriate method that provides reliable result on pollen viability. It is important to note that every procedure requires standardization of protocol according to the sample used. Following different tests are used for assessing pollen viability.

1. In-vitro Pollen Germination Test

It is a simple, speedy, and quantitative test for assessing pollen viability. In this method, a collection/sample of pollen is germinated in vitro and observed under microscope. The percentage of germinating pollens (producing pollen tube) after appropriate treatment and a given period of time is determined. The percentage provides an index of viability of the pollen sample.

Globally, antimicrobial resistance (AMR) is an important public health and development threat (WHO, 2020). Being one of the top 10 global public health threats, the ever-increasing rates in the occurrence of drug-resistant bacterial infections have become a grave public health concern for the governments (Laxminarayan et al., 2013). Moreover, such infections would be difficult to treat and therefore can lead to worse clinical outcomes (Laxminarayan et al., 2013). Worldwide, each year about 700,000 people die from antimicrobial resistant infections and the mortality figures are projected to reach 10 million/ year by 2050 (O’Neill, 2016). The crude infectious disease mortality rate in India is more than 400 per 100,000 persons and at least 23,000 deaths in adults and 58,000 neonatal deaths per year are caused by AMR bacteria (Laxminarayan and Chaudhury, 2016). A 2017 estimate puts the cost of developing an antibiotic at around US$1.5 billion (Towse, et al. 2017). Meanwhile, industry analysts estimate that the average revenue generated from an antibiotic’s sale is roughly $46 million per year. “That’s tiny and nowhere near the.
