Animals worldwide provide meat, milk, eggs, draft power, skins, transportation, and a variety of other useful items. India has a vast livestock population with a diverse spectrum of species. Animal husbandry plays an important role in the life of rural farmers. Animal breeding is an area of science concerned with sound animal husbandry methods. Animal breeding is the use of genetics and reproductive physiology to improve the genetic makeup of animals. The goal of animal breeding is to improve not only individual animals, but the entire animal population. The breeder has two basic tools namely selection and breeding for genetic improvement of livestock. The kinds of selection are natural and artificial selection. In artificial selection, breeder has choice to choose superior animals over the average of population for desired traits and allow them to produce offspring for future generation. Animals are selected using four criteria (basis): individual selection, pedigree selection, family selection, and progeny testing selection. Individual selection selects animals based on their own performances.  Individuals are chosen through pedigree selection using ancestral records. In Family selection,

Type and Potential of Organic Residues

A number of diverse sources of organic materials are available for recycling in agriculture. These are mostly of plant origin and recycled either directly or after having being used as feed or food by animals and humans. In view of high organic content and mineral nutrients in the biomass, these are considered as valuable inputs to improve the soil fertility and crops production. Organic resources are low cost inputs but are valuable based on its potential for nutrients and organic matter content.

Attractive Features of Organic Resources

• Organic matter is the basic resource of several essential plant nutrients.

• It buffers the effects of pH dependent changes on nutrient availability.

• They are generated close to their use.

• They are renewable as they are generated regularly.

• With increasing demand for increasing food production, the potential of organic resources is expected to rise.

• Farmers are familiar with organic resources from time immemorial.

Introduction

The compassionate treatment of animals and consideration for their well-being is an important aspect of livestock farming. Compassions needs to be an integral part of livestock farming as livestock are sentient being. Positive human experiences during handling are essential for ensuring the welfare of animals. Humans play a significant role in the environment of production animals, particularly in commercial cattle production where daily interaction occurs. Intensively farmed animals endure negative emotions that diminish their welfare. For instance, they experience fear from unfamiliar stimuli or from being separated from their social group (Jones, 2011), as well as stress, pain and frustration due to the obstruction of naturally driven behaviors (Dawkins 1998) or the absence of predictability and control over their surroundings (Bassett et al, 2007), along with boredom stemming from insufficient environmental stimulation (Wemelsfelder, 1993). Compassion is a fundamental virtue in veterinary practice, and female-owned businesses in this sector often exhibit this attitude. Compassion, the highest quality of women, is highly valued in veterinary practice, and women-owned enterprises are perfect example of this. They place a high value on compassionate care, acknowledging the close bond between people and animals and making sure each animal gets the attention and assistance they require by focusing on improving the quality of life for all animals and their loving owners.

Slaughter is an act of killing or destruction of animals for food purpose and includes all processes and operations on all such animals in order to prepare it for being slaughtered. It is an expert act requires expertise and willingness. Slaughter is necessarily to be performed in a slaughter house recognized or licensed by authority empowered under law for the time being in force to do so.  Only authorized animals are to be slaughtered for food purpose and restricted animals or animals prohibited for slaughter should not be converted into meat in any case. Animals in pregnancy, has offspring less than three months or under the age of three months, animals not certified by veterinarian for fitness should never be slaughtered. Slaughterman should also have a valid license or authorization issued by municipal or other authority. The persons below eighteen years of age and suffering from communicable or infectious diseases shall not be permitted to slaughter an animal.

SYNOPSIS

Animal source foods (ASF) include any food item that comes from an animal source such as meat, milk, fish, eggs, cheese and yogurt. Many individuals do not consume ASF or consume little ASF by either personal choice or necessity as ASF may not be accessible or available to these people. Animals are used as food either directly or indirectly by the products they produce. Animal source foods (ASF) include any food item that comes from an animal source such as meat, milk, fish, eggs, cheese and yogurt.

Summary

Animal tissue culture is a biological technique in which a piece of tissue is taken from an animal specimen and cells from this tissue are grown and maintained in an in vitro or artificial environment (Harrison, 1907). Aim of cell / tissue culture is actually to make cells as happy in the in vitro conditions, as they are in their natural environment. The objective of this chapter is to highlight those principles and procedures that have particular relevance to the use of cell culture in tissue engineering.

1 History

Animals are culturally worshipped and revered as gods in India by different communities such as cow as Kamadhenu by Hindu religion. The scientific study of animal welfare has rapidly grown during last few years. Many religions follow principles of ahimsa such as Jains and Hindus do not harm cattle; Muslims do not harm pigs etc. Thus caring for welfare of animals is an inborn attitude of majority of Indians. As per the Indian tradition and culture, animals always had a respect and a special place in society. Hinduism, Buddhism and Jainism have always preached kindness and compassion to animals. Each Hindu God or Goddess is seen with an associated animal as vehicle or incarnation. For example, Lord Krishna was a shepherd and is seen with a cow, Lord Rama with the monkeys, Lord Vishnu with the eagle and Lord Shiva with a snake around his neck and the bull ‘Nandi’ at his feet, Goddess Saraswati is the goddess of wisdom and literacy is seen with swan.

Animal Welfare Board of India was started under the stewardship of Late Smt. Rukmini Devi Arundale, well known humanitarian. The Animal Welfare Board of India is a statutory advisory body on Animal Welfare Laws and promotes animal welfare in the country. The board established in 1962 under Section 4 to 10 of the Prevention of Cruelty to Animals Act, 1960 (No. 59 of 1960).  The primary sources of funding of the AWBI are grants from the Government of India. However, contributions, subscriptions, bequests and gifts will also be encouraged.

A disaster (from Latin meaning, “bad star’) is the impact of a natural or man-made event that negatively affects life, property, livelihood or industry often resulting in permanent changes to human societies, ecosystems and environment. The event itself is not a disaster; it is the impact that is a disaster. Their possibility of occurrence, time, place and severity of the strike can be reasonably and in some cases accurately predicted by technological and scientific advances. Hence, we can to some extent reduce the impact of damage though we cannot reduce the extent of damage itself.  The impacts suffered include trauma, starvation, dehydration, infection, disease, shock etc. Animals are often the silent victims of disasters, and there is a real need around for the provision of effective training and management programmes to ensure that their survival and welfare are adequately accounted for. This demands the study of disaster management in methodical and orderly approach.

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.

ETHICS OF ANIMAL USE IN RESEARCH

• The use of animals in scientific research is a controversial issue. Animals have been used throughout the history for anatomical and physiological research as well as for testing toxic substances.
• Many medical advances, including vaccines for polio and rabies, the development of certain antibiotics, anti cancer agents and transplant medicine have been developed by using animals in research.
• But the question is whether it is right or wrong to use animals for these purposes.
• All scientists working with laboratory animals must have a deep ethical consideration for the animals they are dealing with.
• From the ethical point of view it is important that such considerations are taken care at the individual level, at institutional level and finally at the national level.

What are Ethics ?

5.1 INTRODUCTION

One of the generalizations that can be made about soils is that the particles of which they are composed together have a nett negative charge. There are exceptions: for example, some iron- and aluminium-rich tropical soils can attain a positive charge at low enough pH, but such cases are rare. It is nonetheless a fact that most anions are held strongly by the soil complex, and it is the purpose of this chapter to look at some of the reasons why this is so. Historically, the impetus to research in this area has largely been the practical necessity to understand the behaviour of applied phosphate fertilizer, and it is some indication of the complexity of the problems involved that, even after decades of effort by soil chemists and agronomists, this understanding is still far from complete. The reason for this is partly that the soil surfaces themselves are, as has been described by Greenland and Mott (1978) in the companion volume, the product of a ‘dirty’ environment. This generally means that phosphate added to the system has to exchange on sorption with an inadequately characterized suite of anions presorbed on ill-defined surfaces. There are also in the case of phosphate, possibilities of simultaneous precipitation. Faced with these problems, the trend in the literature over the past ten years or so has been to investigate in detail the physical chemistry of the sorption of anions onto simple surfaces which are fairly well understood, in the expectation that this will lead to ultimate comprehension of behaviour in the natural system. The results of many relevant experiments have only recently been published, and so some parts of the account are still at the discussion stage in the literature. This is especially true of phosphate, which looks destined to be a joker in the anion pack for some time to come.

Abstract

By loosely inspiring the actions of neurons in the human brain, artificial neural networks (ANNs) are widely accepted as a powerful nonlinear adaptive approach to tackle complex, dynamic, highly nonlinear, and ill-defined problems in an increasing number of fields of food industry.They have been used extensively in food drying to solve problems of nonlinear function approximation, pattern recognition, data description, optimization, simulation, pattern recognition, control, data sorting, clustering, and noise reduction, due to their massively parallel structure and capability to learn from examples. In this chapter, after providing a brief description of ANN technology and its principles as well as the structure of the most commonly employed ANNs in this context, an example is given to explain how the ANN technique is used for modeling and controlling food drying process. Generally, modeling, prediction, and optimization of heat and mass transfer, thermodynamic performance indicators, and quality parameters as well as physico-chemical attributes of dried foods are the most popular subjects to attract researchers’ attention to apply the ANNs in food drying industry.

Collectively all the Annona fruits technically are syncarpous is composed of more or less numerous carpels coherent with the fleshy receptacle. Fruit has been described as ‘Deliciousness itself’ compared to pineapple, mangostean and cherimoya the finest fruits of the world. Its native place is the mountains of Ecuador and Peru as terra-cotta models of cherimoya fruits are frequently obtained from prehistoric graves in Peru. The word cherimoya is from the Peruvian name ‘cherimuya’ meaning cold seed. Although originated close to the equator the fruit attains best quality or performs better where climate is cold and relatively

Drumstick or Moringa is one of the world’s most useful crops and  is a tropical tree with multiple uses and its main feature is that it  is hardy with tremendous capacity to withstand drought. It is indigenous to the sub-Himalayan track extending from river Chenab to Sharda. It is grown  in  arid to humid areas of the tropical region  as a  human food crop mainly as a vegetable, animal forage crop, medicine, dye and oil yielding crop and for water purification. Among the 13 species known in the family Moringaceae, Moringa oleifera Lam is particularly easy to reproduce and its growth is very fast. The species is characterized by its long, drum stick shaped pods which contain  seeds. Within this species, utilizing its fast growing nature  and bearing fruits or pods selections are made to release varieties which can be grown as annual crop.During the very first year of growth, moringa  grows up to 4 meters and  bears fruit within the same first year (Folkard and Sutherland, 1996). The plant sheds its leaves with  onset of winter, stops producing flowers and virtually fruit set will not be there.

The numerous economic uses of Moringa oleifera together with its easy propagation have raised growing international interest for this tree which originated from India and  found in most tropical countries (Africa, Asia and America). Presently its cultivation on large scale  is seen in  India, Israel, Thailand, South Asian Countries, Africa and Pacific Islands. Presently in India, it occupies an  area of about 40,000 ha with  major growing areas in  Andhra Pradesh, Karnataka and Tamil Nadu which account for  more than 80 % of the area and production in India.

3.1 Tomato

Tomato (Lycopersicon esculentum) is an important vegetable crop. Its 2n= 24.

Floral biology

Flowers are borne in small forked racemose cyme. Anthesis starts at 6.30 a.m. and continues up to 11.00 a.m. Anther dehiscence is longitudinal. It occurs 1-2 days after opening of corolla. The stamen sheds its pollen when the style grows up through anther tube, thus self-pollination occurs. When the stigma protrudes above the anther tube, chances of cross pollination through bees increases. The optimum temperature for pollination is around 21°C.

Flowers blooming in a garden can be preserved by drying them for use in arrangements, decorations and various other applications. Natural dry flowers can be annual or perennial. Some of the important annuals used for dry flower making are described below.

14.1 Annual Flowers

Plants classified as annuals are those that complete their life cycle within the space of one year. Annual flowers are versatile and sturdy. The annuals have many uses in landscaping. Annual flowers are beautiful and garden lovers tend to preserve these flowers throughout. They dry these flowers and store them for use in several beautiful dry flower arrangements.
