It is of valuable tool for students, researchers, professors and a variety of employers, including government agencies, zoos, and food producers.ДЄnimal breeding is a branch of animal science that addresses the evaluation of the genetic value of domestic livestock. The book animal breeding and genetics encompasses topics such as genetic variability, genetic testing, and animal breeding focuses on various aspects of animal heredity, or the passing of traits from one generation to the next. The scientific theory of animal breeding incorporates population genetics, quantitative genetics, statistics, and recently molecular genomics. Selecting for breeding animals with superior EBV in growth rate, egg, meat, milk, or wool production, or with other desirable traits has revolutionized livestock production throughout the world. Animal breeding addresses the evaluation of the genetic value of livestock. The animal breeding and genetics provide new scientific discoveries to age-old livestock production problems to help producers and consumers. The revolution in genetic mapping technology and the advent of whole genome sequences have turned quantitative genetics into one of the fastest growing areas of biology. However, an increased knowledge of biology, especially genetics, has helped in improving the quality of animals and animal products as per the human requirements. This phenomenon is called Artificial selection. Before the discovery of principles of heredity human beings have selected the animals with required characters and learned to develop the plants having the selected characters. Previously the animals were developed basing on unscientific methods. These high yielding animals are produced by hybridization experiments. In dairy and poultry farms high yielding animals are reared. Pickal accomplished the careful drawing of fresh illustrations.ДЇrom the very early days human beings depend on animals and animal products for food and other requirements. Fuchshuber have completed an admirable job in typing my handwritten script and A. Frape for his help in changing my own translation into readable English. lowe much to constructive critical comments on the first edition. It is further hoped that my teaching experience has had some no ticeable impact on style and presentation. Nevertheless it is hoped that this introductory text will stimulate the reader to explore the subject in greater depth and inspire study of the original literature. The extent of work in this sphere has reached dimensions which preclude exhaustive discussion of all its aspects in a volume of this size. This has modified and in some cases even changed previously held conceptions, necessitating a thorough revision of the first edition. Since the first edition, considerable development has occurred both in the basic and in the more applied fields. Therefore, it brings into focus the basic principles of animal breeding, which are illustrated with per tinent examples however, it is not intended to give recommendations for particular situations. This book attempts to outline population genetics and quantitative ge netics as they pertain to animal breeding and to discuss the theoretical aspects of this field of agricultural activity. It is felt that the reader which are likely to comprise mostly of graduate and post graduate student of animal breeding and researcher will be able to get a deeper insight and better perceptions into the realm of the dynamic science of animal breeding. The subject matter has been dealt with in a logical sequence so that the reader is conveyed from simple to more complex interpretation with relative ease. In this book, brief history of population genetics, domestication of livestock species, classification of breeds, economic characteristics of different livestock species & poultry and their importance, basic statistics, qualitative and quantitative inheritance, gene and genotype frequency and factors influencing gene frequency, values and means of population, methods of estimation and uses of heritability and repeatability, correlations, selection, response to selection, basis of selection, progeny testing, open nucleus breeding system, sire evaluation, methods of selection, breeding or mating systems, heterosis or hybrid vigor definitions and current livestock and poultry breeding programmes have been discussed in different s. This book attempts to describe applied breeding methods for different domestic animal species as currently implemented.
