Learn how to successfully breed live food for the animals in your care with this guide for all professional and amateur vivarium owners. It provides easy-to-follow instructions for the development of long-term breeding environments for food animals and describes in detail how to raise a wide variety of live food such as plankton, worms, crustaceans, mollusks, insects, mammals such as mice and rats, and includes some live foods that are rarely used. This book offers advice and should answer questions that might arise during the raising of food for the vivarium. It contains information that is necessary in providing your vivarium animal with a healthier, longer life.
Addressing principles associated with breeding animals for enhanced health and resistance to specific diseases, this book provides a review of the field illustrated with examples covering many diseases of importance to livestock production, across all major livestock species. Authored by experts in the field, this updated edition covers techniques and approaches, viruses, TSEs, bacteria, parasites, vectors, and broader health issues seen in production systems, including metabolic diseases. The book will be an essential reference for professionals in the field, scientists and researchers, students, breeders, veterinarians, agricultural advisors and policy makers.

Genetics and Breeding for Disease Resistance of Livestock is a solid resource that combines important information on the underlying genetic causes and governing factors for disease resistance in food animals and applications for breeding purposes. It describes genomics at each species level to help researchers and students understand disease resistance and immunology using genomics and its application in breeding for disease resistance. This useful reference makes it easy for readers to understand and undergo further research in immunology and disease resistance for livestock. It includes novel applications and research material that is ideal for students, teachers, academicians and researchers. Presents basic principles and protocols to describe research methodologies through diagrammatic illustrations with figures, flow charts, examples, and references Covers various disease occurrences in livestock and the methodologies available to identify the various pathogens responsible for these diseases Includes advanced breeding techniques and practical applications
The determination of when, how, how often and with whom an animal breeds is moving rapidly away from evolutionary pressures and towards human purposes: these include the breeding of around 50 billion mammals and birds for food production annually, the breeding of pedigree dogs and cats, racing dogs and horses, specialised laboratory animal strains and the use of reproductive science to conserve endangered species or breeds and to limit unwanted populations of pests and non-native species. But the ethics and sustainability of this takeover of animals' reproductive lives have been insufficiently examined by either professionals or the public. This book discusses the methods, the motivations and the consequences of human intervention in animal breeding in terms of animal health, behaviour and well-being. It explores where we are now and the choices ahead, and looks to a future where we have more respect for animals as sentient beings and where we could loosen the reins of reproductive control.
This book attempts to describe applied breeding methods for different domestic animal species as currently implemented. 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. 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. 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.

Excerpt from The Breeding of Animals The problems of the animal-breeder may all be grouped under the three subjects, reproduction, inheritance, development. The mere multiplication of the species is now, and always has been, the major work of the breeder of domestic animals. But the real breeder is not only concerned with the production of mere numbers of animals of a given species but is primarily interested in securing animals possessing the largest number of desirable qualities and the least number of qualities undesirable to man. How to maintain the good qualities that have already appeared in an individual, and how to cause other and better qualities to become dominant in future individuals of the same species, is the problem of inheritance that chiefly concerns the breeder of the domestic animals. The highest attainments in the breeder's art have come only to those who have had a good knowledge of the principles and laws of heredity. The development of animals from the fertilization of the egg to maturity and their proper maintenance throughout their productive lives is second in importance only to inheritance. The environment of the animal, including food, climate, and exercise of functions, determines the degree of development in the individual animal. The term Development, as used in this connection, has reference to the unfolding of capabilities that have come to the animal through inheritance.
