Abstract

Agriculture is the major sector for the livelihood of the billions of people worldwide. Increasing population and decreasing arable lands are the major concern for the fulfillment of the desired food production. After green revolution more production in the crop is obtained by worldwide. Several insects and pests are responsible for the inhibition of desired production in agriculture. Therefore, pesticides play a major role in the control of destructive insects and pests. After ban of organochlorine pesticides, organophosphorus pesticides has been used vigorously. Beside the effective pest management in agriculture, residual organophosphorus pesticides are more lethal for human and other living creature. Monitoring of these compounds is very much essential in the food and agricultural samples. Chromatographic techniques are well adopted techniques for the hundreds of residual pesticides. Introduction of various analyzers in chromatographic techniques improve the monitoring of the residual pesticides from different samples. Therefore, recent advancement in residual pesticides isolation and chromatographic techniques has been discussed in this book chapter.

Field-ready pregnancy diagnostic tests are an important tool for improving reproductive performance in livestock. They help optimize breeding programs, resource allocation, and decision-making processes, leading to better economic outcomes and sustainable livestock production systems. Pregnancy diagnosis is an important tool for improving reproductive performance in livestock for several reasons:

1) Timely management: early and accurate pregnancy diagnosis allows farmers and livestock producers to make timely decisions about the management of pregnant and non-pregnant animals. This includes adjusting feeding regimes, providing appropriate veterinary care, and establishing breeding plans.

2) Optimized breeding programs: In livestock, controlling the timing of pregnancies is critical to maintaining a well-organized breeding program. With accurate pregnancy testing, farmers can identify non-pregnant animals and breed them back earlier, optimizing resource utilization and shortening the generation interval.

3) Resource allocation: early identification of non-pregnant animals helps avoid unnecessary allocation of resources such as feed and health care to animals that will not produce offspring in the current cycle. This efficient allocation of resources is essential to maintaining a cost effective production system.

4) Lower costs: unproductive animals consume resources without contributing to farm productivity. By quickly identifying non-pregnant animals, farmers can avoid the cost of keeping these animals during their non-productive period.

5) Genetic improvement: for livestock programs focused on genetic improvement, accurate pregnancy diagnosis is critical. It enables the selection and promotion of animals with desirable traits for breeding purposes, thus accelerating genetic progress.

Abstract

It is well known that drying is an important unit operation in food processing industries, essentially used to extend the shelf life but also in making innovative processed products such as snacks with desired functionalities. Although drying of food products is carried out traditionally using several methods, the quality and energy aspects have been major focus of food drying research in the last decade or two. This is achieved by modifying and/or optimizing the existing drying systems, improving pre and post processing of the product, combination of more than one dryer type or developing altogether a new drying technique. There several dryer types which can give extremely good product quality, however, cost-effectiveness can be a major issue. It is necessary to balance both good product quality and minimum energy usage in order to sustain highly competitive market. This lecture will provide an overview of conventional drying methods used for foods, followed by some advances in these conventional methods and a discussion on some new drying techniques developed in recent years that are either commercialized or have potential of industrial use.

Abstract

Fusion is a well known entity in various fields (e.g. medical imaging, weapon detection, flood monitoring etc.) that surmises information originating from several modalities. This chapter is an attempt to assort the various image fusion techniques available for human face recognition and to put a review of the advancements being made by the different researchers. The various types of fusion those have been used or may be used for face recognition have also been discussed here.

Tissue Doppler Imaging

Doppler echocardiography relies on detection of the shift in frequency of ultrasound signals reflected from moving objects. With this principle, conventional Doppler techniques assess the velocity of blood flow by measuring high-frequency, low amplitude signals from small, fast-moving blood cells. In TDI, the same Doppler principles are used to quantify the higher-amplitude, lower-velocity signals of myocardial tissue motion.

There are important limitations to TD interrogation. As with all Doppler techniques, TDI measures only the vector of motion that is parallel to the direction of the ultrasound beam. In addition, TDI measures absolute tissue velocity and is unable to discriminate passive motion (related to translation or tethering) from active motion (fiber shortening or lengthening). The emerging technology of Doppler strain imaging provides a means to differentiate true contractility from passive myocardial motion by looking at relative changes in tissue velocity.

Cage Fully enclosed container for housing rabbits which, because of its size, restricts freedom of movement by rabbits and limits the provision of environmental enrichment strategies. Cages are usually constructed from metal or plastic, with solid or mesh sides.

1. Introduction:- Understanding Good Laboratory Practices (GLP)
1.1 Definition and Core Principles of GLP
The Organisation for Economic Co-operation and Development (OECD) defines Good Laboratory Practice as “a managerial quality control system that governs the organizational process and the conditions under which non-clinical health and thus, environmental safety studies are well planned, executed/ performed, vigilantly monitored, properly recorded, reported, and finally archived”. This definition highlights that Good Laboratory Practices (GLP) is a comprehensive framework focused on ensuring the quality and integrity of the entire study lifecycle, rather than dictating the scientific validity of the research itself. The primary goal of GLP is to ensure process integrity and data traceability, which are essential for the regulatory acceptance of safety data for a variety of products. These products include pharmaceuticals, pesticides, cosmetics, veterinary drugs, food additives, feed additives, and industrial chemicals, all of which undergo non-clinical testing to assess their potential health and environmental risks. It is important to note that GLP principles specifically apply to these non-clinical studies and exclude research involving human subjects. The OECD Principles of GLP are internationally recognized and serve as the basis for GLP regulations in numerous countries worldwide. These principles outline the responsibilities of key personnel involved in non-clinical studies, including test facility management, the study director, study personnel, and quality assurance personnel. Furthermore, they establish minimum standards concerning the suitability of facilities and equipment to perform studies, as well as the necessity for comprehensive Standard Operating Procedures (SOPs) to guide all aspects of laboratory operations. The core principles of GLP encompass a wide range of elements critical to ensuring the quality and integrity of laboratory studies. These OECD principles of Good Laboratory Practices (GLP) include: the proper organization team and personnel staff members within the testing facility, the well establishment of a robust quality assurance programme, the better suitability and proper maintenance of various necessary facilities, the efficient management of apparatus, materials, and reagents, the characterization and control of test systems, the handling of test and reference items, the development and adherence to Standard Operating

These products were originally flavoured with the herb marshmallow but a modem marshmallow is a foam that has been stabilised by a gelling agent. The traditional material for marshmallows is egg albumen which acts both as a foaming and gelling agent - this gives light, soft gel. Gelatine is now more commonly used, and once again can act as both a whipping and gelling agent. A gelatine marshmallow is soft and rubbery but heavier than an egg albumen one. Further gelling agents, e.g., pectin, agar and starch all give a soft, short textured gel. These gelling agents have the advantage of being vegetable products but have the disadvantage of normally needing a whipping agent as well. Enzyme-modified soya products have also recently become available for this use.

Introduction

Aflatoxins are a group of highly subsituted coumarine, of which aflatoxin B1 and G1 are  most  highly hepatotoxic (toxic to liver) to animals. The toxins are produced by some strains of Aspergillus flavus and other species of Aspergillus which develop in many food stuffs, particularly groundnuts. cottonseed, and their cake and flour. Protein concentrates meant for babies as well as adult are now a day  made from groundnut flour and the cakes are used as feed for poultry and livestock. It has been found that even fodgrains such as maize, rice and wheat are attacked by the fungus producing the toxins.

Introduction

The term ‘mycotoxin’ coined in 1962 in the aftermath of death of about 1,00,000 turkey poults in London, due to “Turkey X disease” in 1960, linked to a peanut meal contaminated with aflatoxins. Now, about 300 to 400 toxic fungal metabolites have been identified as mycotoxins, of which some are capable of inflicting deleterious effects to animal and avian health. The most commonly affected feedstuffs are cereals (maize, sorghum, barley, wheat, and rice meal), oilseeds (groundnuts) and oilseed meals (cottonseed meal). There are three major genera of fungi that produce mycotoxins: Aspergilius, Fusarium and Penicillium (Bennett and Klich, 2003). Among these, the Aspergillus species are of much concern as they are responsible for the production of aflatoxins, the most potent fungal toxin causing aflatoxicoses that have detrimental effects on living beings (Barret, 2000).

Precipitation and agglutination reactions are similar except in that for precipitation reaction antigen must be in soluble form. The precipitation reaction is highly specific and very sensitive for the detection of antigen being capable of demonstrating antigens in dilutions of 1:100,000 to 1: 1,000,000 or more. It is important to bear in mind that antigens used in precipitation reactions are of molecular size not cellular. A soluble antigen reacted with its homologous antibody at the optimum proportions produce an insoluble precipitate. The essential ingredients for precipitation test are soluble antigen (precipitinogen), antibody (precipitin) and an electrolyte (normal saline).
a) Precipitation ring test
The antigen is carefully layered over the antiserum, without mixing so that an interface is formed. Diffusion of each reagent will then occur into the other. If the system is homologous, precipitation will occur at the point in the tube, where the proper ratio of antigen to antibody is reached. Eg: Ascoli’s test for anthrax diagnosis.
In advanced decomposition of animals when cultures would be almost impossible, the precipitation method of Ascoli is used for diagnosis of Anthrax. This method is a mixing of immunized rabbit serum with an extract of organs under examination for the production of a precipitate.
Procedure
1. Grind up organs or blood of suspected animals.
2. Suspend in saline.
3. Boil for five minutes
4. Filter through filter paper and allow to cool
5. Carefully stratify 0.5 ml of this extract on 0.5 ml immune serum in small test tubes.

Agarose gel electrophoresis is the easiest and commonest way of separating, capable of resolving mixtures of DNA fragment that cannot be separated conveniently by other procedures. The purpose of the gel might be to look at the DNA, to quantify it or to isolate a particular band. The DNA is visualised in the gel by addition of ethidium bromide. This binds strongly to DNA by intercalating between the bases and is fluorescent meaning that it absorbs invisible UV light and transmits the energy as visible orange light.

Agarose, which is extracted from seaweed, is a linear polymer whose basic structure is shown in figure.

After fertilization and zygote formation, in utero development can be divided into two stages, i.e. embryonic and foetal. Embryo period refers to the time between fertilization and the development of organ primordia. During the embryonic period, fast development occurs, and primordia of most organs are established. During the foetal stage, which lasts from the end of the embryonic period until parturition, the body’s systems begin to develop and function.

Ageing of meat is also known as conditioning or tenderising or ripening or maturing and sometime resolution of rigor. It is a process of holding unprocessed meat above freezing point under controlled conditions. By this process we can make muscle soft and pliable thus meat becomes tender. When we keep the meat above freezing point at temperature between 0-3ºC then all those changes occurs which are normally occurs at higher temperature i.e. atmospheric oxidation and enzymatic action of fat, bacterial action etc. When this temperature range becomes below freezing point then it inhibits completely the enzymatic action in the muscles. Ageing is required for marked increase in flavour, juiciness and tenderness of meat. In this process action of enzymes in meat plays key role while bacterial action is not of any importance. Meat tenderness and taste are definitely improved if carcasses or vacuum packed cuts are conditioned after slaughter but paradoxically beef is quite tender just two hours after slaughter and several days of conditioning are required to recover this degree of tenderness.

During the contraction of muscles, thick and thin filaments sliding to each other and decreases the length of sarcomeres. In turn, this decreases the length of fibrils, fibres and the whole muscle. If these muscles remain in contracted length when rigor develops, it causes massive overlap of thick and thin filaments leading to severe meat toughness. It is also necessary to avoid the cooling of meat too rapidly after slaughter, otherwise it cold-shortens and gets tough. If we avoid cold-shortening of muscles during conditioning, it will increase meat tenderness. But with too much conditioning, weight loss, surface spoilage and the cost of refrigerated storage increases.

Ageing of carcasses with little or no fat cover is not recommended by meat specialists. Because these carcasses loose moisture rapidly, loose weight excessively and discolour the meat surface rapidly. In addition, lean meat is also susceptible to deterioration through microbial growth, slime formation by bacteria and mould growth etc. Ageing is important for beef and buffalo meat while pork and lamb do not require ageing because they are slaughtered in the age where they are young and inherently tender. Additionally, the unsaturated fats found in pork fat oxidize during ageing causes rancidity and off flavour. Veal has very little protective fat covering and is high in moisture; thus it does not lend itself to ageing.

Principle
The principle of the test is that antibodies possess two antigen-binding sites that will attach specifically with the antigenic determinants on the surfaces of the bacteria, cells or particles. Under suitable conditions one antibody molecule will combine with the determinant group on the surfaces of two bacteria and in this way a lattice is formed. These lattices are generally visible with the naked eye as clumps and they sediment readily due to the large size of the clump.
Pre-requisites for Agglutination Reaction
a) The antigen (agglutinogen) should be in particulate form, which will remain in suspension for sufficiently long time.
b) The antibody (agglutinin) should be directed to the target surface epitope.
c) Antigen – antibody should be present in optimal proportions.
d) An electrolyte is necessary for the reaction to take place and usually the reaction is carried out in physiological saline solutions (0.85% NaCl). Because of the overall negative charge on red cells or bacteria at neutral pH it is difficult for them to come close enough, so that for molecule such as IgG antibodies are able to form a bridge between epitope of two different cells or bacteria. The presence of salt tends to neutralize the charge effects to allow agglutination.
Plate Agglutination Test
This is employed to screen sera within a short period for preliminary testing.
Materials
• Brucella abortus coloured antigen
• suspected serum
• glass plate.

2.1Introduction

Agriculture includes both self-employment and wage employment. This require precise information about who does what. Majority of farmers have small Land holding and landless labourers. This needs understanding of activity performance of men and women. Gender-based division of labour is universal, but culture and community diversities cause differentiation. Gender, therefore, has to be recognized as the social characteristic that cuts across caste, class, occupation, age and ethnicity. It is gender that differentiates the roles, responsibilities, resources, constraints and opportunities of women and men in agriculture for which precise gender information is the need of the day. Building gender into agricultural development will lead to: Building inherent strength of women and men to mutually learn, Overcoming gender based prejudices etc.

2.2

Importance of Gender in Agriculture Agriculture play an important role in livelihoods of the rural poor and achievement of the Millennium Development Goals (MDGs). Agriculture can be the engine of growth and is necessary to reduce poverty and food insecurity. The changes in Agriculture sector generate new sources of opportunities for livelihoods and food security, they also pose significant qualms. Equity distresses are being raised.

Watermelon (Citrullus lanatus), family Cucurbitaceae originated from West- Africa augurs well as a very promising scrambler and trailer fruit plant.

Agribusiness: A Dynamic Concept
Agribusiness, an ever-evolving concept since its introduction in the 1950s, encompasses a broad spectrum of business and management activities linked to agriculture. Downey and Erickson defined agribusiness as encompassing all activities undertaken by firms that supply inputs to the farming sector, produce agricultural products, and process, transport, finance, or market these products. Chait extended the definition to include agriculturally related businesses such as warehouses, wholesalers, processors, and retailers.
In developed countries, agribusiness is broadly defined as the total output from farm production and processing at both pre- and post-farm gate stages. In contrast, in developing nations like India, agribusiness is categorized into four distinct sub-sectors:
1. Agricultural inputs
2. Agricultural production
3. Agro-processing
4. Marketing and trade
These sub-sectors contribute to adding value and utility to agricultural goods. Agribusiness has emerged as a specialized field within management sciences, focusing on activities and linkages, both backward and forward, related to production, processing, marketing, trade, and distribution of food, feed, and fiber, along with the supply of inputs and services.
