Organic Animal Husbandry happens to be an emerging area which requires attention given its growing potential for domestic as well as export market. The start-ups including farmers engaged in organic farming and entrepreneurs need support in terms of information, technical knowledge, financial, incubation, hand-holding and marketing of organic animal products. Organic animal husbandry has been defined as a system of livestock production that promotes the use of organic and biodegradable inputs from the ecosystem deliberately avoiding the use of synthetic inputs such as drugs, feed additives and genetically engineered breeding inputs, while ensuring the welfare of animals. There are four principles of organic farming viz; principle of ecology, principle of health, principle of fairness, and principle of care, which organic systems must always take into consideration. In order to achieve the animal welfare, environmental protection, resource-use sustainability and other objectives, certain key principles are adhered to under organic livestock production systems. The organic livestock & poultry standards have been notified by APEDA under National Programme for Organic Production (NPOP). All operations related to organic livestock including goat & poultry production are to be governed by these standards in India.

Rice is the primary food source for half of the Asian population. Nearly 2,000 million in this region obtain 60 to 70 per cent of their calories from rice and its products. Considering the importance of the crop, United Nations General Assembly declared 2004 as the “International Year of Rice” (IYR). In India, the crop covers one-fourth of the total cropped area. About half of the Indian population use rice as their staple food.

Rice based cropping systems are not only important for food security but also for maintaing an ecological balance. Low land rice fields conserve water and prevent runoff .They preserve the sustainability of the ecosystem.

Developmental Anomalies

Congenital icthyosis

Congenital icthyosis is scaly epidermis which resembles the skin of fish and occurs due to a simple autosomal recessive homozygous gene in calves. This condition is characterized by scaly, horny, thick epidermis divided into plates by deep fissures. Microscopically, there is thick keratin layer over the epidermis (Fig.1.1).

Epitheliogenesis imperfecta

Epitheliogenesis imperfecta is a congenital defect characterized by discontinuity of epithelium on skin leaving patches without squamous epithelium mostly at feet, claws and oral mucosa. Such defect may occur in calves which succumb to infection after birth or such foetus may abort. This disease condition is inherited as an autosomal recessive trait.

This chapter introduces tree improvement approaches aimed at developing forest species with enhanced resistance to biotic and abiotic stresses.

By integrating breeding strategies with modern technologies and climate-resilience objectives, the chapter emphasizes the development of improved forest trees capable of maintaining growth, productivity, survival, and ecosystem functions under changing environmental conditions.

SUMMARY

Fly ash, a waste product generated by coal based thermal power plants. The annual production of fly ash in the country has increased from 40 million tones in 1994 to 110 million tones in 2004 and it is expected that by 2012 the annual production of fly would reach the mark of 170 million tones. Owing to its physico-chemical characteristics, it has a vast potential for use in agriculture, forestry and wasteland reclamation. Application of fly ash into soil has been reported to increase the water holding capacity, hydraulic conductivity, porosity and decrease bulk density, modulus of rupture and surface encrustation. The studies conducted by various organizations on fly ash use in different crops have revealed significant increase in the crop yields such as wheat, maize, paddy, soybean, sunflower and vegetables like brinjal, tomato, potato, cabbage. Application of fly ash has been found to increase the level of heavy metals  viz., Co, Pb, Mo, As and Se as well as the activity of radio-nuclides i.e., ⁴⁰K, ²²⁶Ra, ²²⁸Ac  in the soil- plant system; however, the levels of all these heavy metals and radio-nuclides were found to be well below the permissible limits.

Embry Transfer Technology (ETT)

Definition: The process of removing one or more embryos from the reproductive tract of a donor female and transferring them to one or more recipient females.

7.1 Introduction

The integral calculus is concerned with the opeartion of “integration” which is the reverse process of differentiation. If f '(x) represents the differential coefficient of f '(x), then the problem of integration is to find f(x) from f '(x).

7.2 Integration of a Function Containing a Constant

If we integrate a function containing a constant factor, this factor must also be a factor of final integral.

Pathology of Muscles

Equine Rhabdomyolysis

It is also known as Azoturia or Monday Morning Disease. The disease occurs in well fed horse after a spell of inactivity. Suddenly after walking a few steps, the horse is unable to move further and feels pain with intense sweating and hardening of muscles.

Etiology

• Accumulation of lactic acid in muscles.

• High glycogen storage.

• Lack of oxygen supply.

Macroscopic features

• Hardening of muscle just like wood.

• Urine is dark brown with myoglobin – myoglobinuria.

• Tonic spasms in muscles.

• Atrophy of affected muscles in chronic cases.

A. Tomato and Tomato Products
Tomato though botanically a fruit is generally considered a vegetable because of how it is consumed. Commercial products from tomatoes include juice, puree, paste, ketchup, soup canned and dehydrated tomatoes. Processing of tomato is now practised from home scale level to large scale enterprise. As a semi-finished product, tomato puree is prepared on a small scale while at a large scale, tomato paste has gained commercial significance. Both puree and paste are used for the preparation of different finished products like ketchup, juice, soup etc. The method for preparation of these products is well standardized, however, some modifications concerning recipes are made in the processing plants owing to variations in the quality of the raw material. The methods for the preparation of different tomato products are discussed as under: -
I. Tomato Juice/Pulp
Tomato juice is an unconcentrated product consisting of a liquid with a substantial portion of the pulp, expressed from ripe tomatoes with or without the application of heat and the addition of salt. Tomato pulp/juice is the basic ingredient for the preparation of different tomato-based products such as tomato puree, paste, ketchup etc. Fully ripe tomatoes are used for the preparation of tomato juice/pulp. All green, blemished and overripe fruits should be rejected as they adversely affect the quality of the product. The juice obtained from overripe tomatoes is usually thin and unpleasant. The juice should be deep red in colour with a characteristic taste and flavour. The juice shall have about 0.4% acidity expressed as citric acid. Cane sugar (1%) is added to further improve the taste and flavour of the finished product.

Introduction

Integrated disease management in horticultural crops are of paramount importance these days, keeping in view that a single management practice cannot control multiple diseases in a particular agro ecological system. It is therefore worthwhile that all management practices are integration of cultural, physical, biological and chemical control strategies. The routine application of fungicides for insurance purposes is not appropriate, as it does not focus the proper attention on the real problem and can lead to resistance and potential environmental issues. Fungal, bacterial, viral diseases cause a great damage to the horticultural crops thus resulting in economic losses to the farmers. The extent of damage varies from year to year, location wise and variety involved. The pathogens responsible for causing diseases affect the crop at various stages of their development right from seedling stage to harvest. The manifestation of a disease can be in the form of different symptoms viz., damping off, leaf spot, blight, wilt, etc. It is thus important to properly identify a particular disease in a crop on knowledgeable basis to reach a particular end of profitability. As such, a proper disease diagnosis is of paramount importance.

The green revolution enhanced the food grain production by increasing  productivity of the arable crops as the only means of expanding output. The impact of this ‘revolution’ was first realized especially in the north Indian states of Punjab, Haryana, and western Uttar Pradesh. Since the new technology was based on use of seeds of high yielding varieties, increased use of irrigation and chemical fertilizers, pesticides and farm mechanization; the incremental gains in productivity of late began to end and food production started stagnating, and in many places it even acquired a decreasing trend. It is well accepted fact that ‘success always has its costs and green revolution has been no exception’. Critics of green revolution point to the environmental and health hazards due to increased use of agro-chemicals and the vulnerabilities that is there due to the spread of monocultures in which indigenous land races have been ignored and least emphasis was given on cropping systems based on crop diversification.

Mungbean is one of the most important pulse crops. It is grown in almost all parts of the country. Mungbean is primarily a crop of rainy season; however, with the development of early maturing varieties, it has proved to be an ideal crop for spring and summer seasons. Middle of March to last week of June is the most suitable growing period where there is a plenty of life-giving sunshine. During this period high temperature and low humidity keep insects and disease infestations at their lowest. Summer season offers an excellent opportunity for raising short duration pulses.

Introduction

Owing to several biotic and abiotic stresses, the problem of agrarian distress in India has accentuated in recent years. The Indian government set a target of doubling farmers’ income by 2022–2023 in its annual budget for 2016–17 and started a number of initiatives to achieve this goal, including better irrigation efficiency, crop insurance, market infrastructure improvements, organic farming promotion, soil health restoration, and others. The pathway for doubling of farmers’ income encompasses several dimensions, from production to post-harvest management. These include: bridging yield gap, crop diversification, improvements in total factor productivity and proper management of irrigation (GoI, 2007, Evenson et al. 1999) alongwith the provisions of market and institutional support for efficient post-harvest management. With respect to Himachal Pradesh, in order to improve the productivity levels of existing crop enterprises and promote the diversification of cropping systems, various steps have been taken by the line departments which include the creation of water harvesting and irrigation infra-structure, skill up gradation of farmers, subsidy on critical inputs like seed, fertilizers, plant protection materials, market access through information technology and village road network, crop insurance schemes, etc. The impact of these interventions is reflected through the continuous increase in the productivity levels and inclination of farming community towards the adoption of new crop enterprises vegetables and fruit crops.

Sterilization is a thermal process aimed at destroying all microorganisms and microbial spores in milk, ensuring the product is microbiologically safe and shelf-stable at room temperature for extended periods. It is primarily used in the production of sterilized milk and evaporated milk, with typical conditions involving heating at 116°C for 15 minutes. This process kills all microorganisms and also inactivates all milk enzymes, including plasmin, which might otherwise contribute to spoilage during storage. However, enzymes produced by psychrotrophic bacteria should not be present in raw milk, as they are highly heat-stable and may remain active even after sterilization. Sterilized milk can be stored at room temperature for longer period. Sterilization kills all microorganisms and inactivates all microbial spores that may germinate under the storage conditions of the product in the market.
The Food Safety and Standards Authority of India (FSSAI) define “sterilization” in relation to milk and milk products as the process of heating the product in a sealed container continuously to at least 115°C for 15 minutes. This treatment ensures that the milk can be preserved at room temperature for a period of not less than 30 days.
In-bottle sterilised milk is a shelf-stable dairy product produced by sealing milk in glass bottles and subjecting it to high-temperature heat treatment. Typically, the milk is heated to temperatures ranging from 110°C to 121°C for 15 to 30 minutes. This process effectively destroys all vegetative microorganisms and bacterial spores, making the milk microbiologically safe and extending its shelf life up to 6–9 months without refrigeration. The heating is usually done in batch retorts or autoclaves after the milk has been bottled and sealed. Although the process ensures safety, it often leads to a slight cooked flavour and some nutritional losses, particularly in heat-sensitive vitamins such as vitamin B1 and vitamin C.

Introduction 
Polymers are mostly distinguished from metals by their property of inability to conduct electricity. Because of the insulating properties, polymers find advantages for many applications of plastics. However with the discovery of poly sulphur nitride [(SN)x], which acts as super-conductor at low temperature the evolution of conducting polymers began in 1975. After two years the linear conjugated organic polymer polyacetylene treated with gaseous bromine or Iodine found to have metallic properties. Some examples of conducting polymers are polyaniline, polypyrrole and polythiophene etc. Conducting polymers are organic polymer, possesses the magnetic, electronic, electrical properties, mechanical properties, and processibility etc. These properties are most commonly related to the conventional polymer. The transformation of polymer from insulator to conductor is called doping. For example: the effect of conductivity due to the absorption of I2 into polyacetylene is analogous to the effect of doping of arsenic, boron, and phosphorus into silicon to make semiconductor. Doping and undoping can be achieved in conducting polymers by an alternate route of electrochemical oxidation and reduction. Doping includes either the removal of electrons from or addition of electron to the conjugated backbone of conducting polymers. Doping is therefore of two types: Oxidative doping (p-type): In this case, the polymer backbone carries a positive charge due to removal of an electron by ordinary oxidation. Examples of p-doped conductive polymers are polyacetylene, polyaniline, polypyrroles etc. The p-doping causes oxidation of the polymer backbone to form cations. When these cations move along the polymer backbone in an electrical field, the polymer is electrically conductive. Reductive doping (n-type): the polymer backbone acquires negative charge by receiving electrons. Ex: Polyacetylene can be n-doped by alkali metals but these are less explored because they are very much sensitive towards atmospheric air than specific undoped type polymer. According to the principle of electroneutrality, doped conducting polymer needs counter ion to balance the opposite charges in the polymer backbone. These counterions are called dopant. Some common examples of dopants are usually small anions e.g. Cl-, I-, and SO4 2-. However poly-electrolyte like p-toluene sulphonic acid can act as the dopant. The process by which the doped polymer loses its charges and becomes an insulator is called undoping. For a doped conducting polymer with isolated small anions as dopants, undoping is accompanied by the loss of the dopant. Undoping causes the conductive polymer to lose its electrical conductivity and useful optical properties.

Introduction 
In healthcare settings, risk management is not a novel idea. There is a wealth of research on risk control in the supply of medications, in-vitro diagnostics production, pharmaceutical manufacture, health information protection, & healthcare process management. Risk management is an important part of patient safety programs in developed countries. An important aspect of quality improvement in laboratories is risk management, which requires an evaluation of every testing method. All the working laboratories must perform this repeated preventive means at least once a year. The safety of laboratory workers, the caliber of results, and environmental preservation all depend on risk management in good laboratory practices (GLP). These are a few GLP risk management techniques. GLP- The Concept In accordance with excellent laboratory practice, risk management should be implemented by evaluating every laboratory procedure to guarantee the safety of both patients and staff. When a GLP facility implements a risk-based inspection procedure, risk assessments will be documented. QA inspection programs will frequently cover widespread operations, but the frequency & extent of the inspection may not take into account or represent the risk associated with each action. By putting quality control procedures into practice, one can learn about the shortcomings of a particular activity and use this information to focus the quality assurance program. According to the OECD Principles of GLP, or “the principles,” there are three different kinds of quality assurance inspections: process-, study-, and facilitybased. Risk Management The process usually begins with the creation of management committee for risk, which consists of important Laboratory staff members and a few ad hoc people chosen by the primary members. All technical laboratory procedures (pre-, examination-, & post-examination) will undergo a process flow analysis

The arid regions of India, spread over 3,17,090 sq. km account for 12% area of the country. The western Rajasthan carries the onus of nearly 62% of arid area. Dryland farming is the main occupation of the people in Indian arid zone. More than 70% of the population in the region is engaged in dryland farming on more than 90% of cultivable lands. The average farm family in Indian arid zone consists of 6-8 members possessing 4-6 hectares of land. The over-exploited fragile natural resources are predominantly under mixed farming - pastoral as well as arable. Farming is almost entirely rainfed in this zone with low and unstable yields.

QTL Traits

Polygenic inheritance, also known as quantitative or multifactorial inheritance refers to inheritance of a phenotypic characteristic (trait) that is attributable to two or more genes and their interaction with the environment. Unlike monogenic traits, polygenic traits do not follow patterns of Mendelian inheritance (qualitative traits). Instead, their phenotypes typically vary along a continuous gradient depicted by a bell curve. Though not necessarily genes themselves, quantitative trait loci (QTLs) are stretches of DNA that are closely linked to the genes that underlie the trait in question. QTLs can be molecularly identified (for example, with PCR or AFLP) to help map regions of the genome that contain genes involved in specifying a quantitative trait. This can be an early step in identifying and sequencing these genes.
