Book Description
First published in 1943, “Animal Breeding Plans” contains a detailed guide on animal breeding designed for students with experience of genetics, embryology, breeds, and stock judging. It aims to furnish the reader with a clear understanding of the means available for improving the heredity of farm animals, especially what each possible method will or will not do well. Highly recommended for modern farmers and animal breeders. Contents include: “Origin and Domestication of Farm Animals”, “Consequences of Domestication”, “Beginning of Pedigree Breeding Methods in the United States”, “History of Animal Breeding Methods in the United States”, “Relation of the Breed Association to Breed Improvement”, “Genetic Principles in Animal Breeding”, “Mendelian Basis of Inheritance”, etc. Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with a specially-commissioned new introduction on farming.

Book Description
Livestock rearing is an integral part of socio-economic framework of India since time immemorial. Livestock sub-sector being a vital component of agriculture sector, plays a multidimensional role and acts as a tool in achieving nutritional security, employment generation and socio-economic development of rural sector, particularly among the landless, small, marginal farmers and women. India possesses huge livestock population of varying production potentials, distributed across different agro-ecological zones under different operational and livestock holding size. Hence, it requires different package of practices for their management. Further, factors like drivers of development change and climate change pose many challenges to this sector. Farm animal management encompasses integrated and precise application of basic scientific principles of breeding, feeding, heeding and weeding in general as well as in times of specific need. Therefore, an attempt has been made in this book to cover all these basic and applied aspects of livestock management in detail. In the perspective of reorganization of the syllabus of veterinary science and animal husbandry programme. This book is appropriately divided into fifteen s covering almost each and every aspect of livestock production management.

Book Description
This special re-print edition of Professor Eugene Davenport's book "Principles of Breeding" is a complete guide to the breeding domestic animals and plants. Written in 1907 by one of the leading professsors of Animal Husbandry of his day, this text includes details about the art of breeding animals or plants for production, exhibition or other selective purposes. Chapters include Variation in General, Morphological Variation, Substantive Variation, Functional Variation, Mutations, Causes of Variation, Type and Variability, Heredity, Prepotency, Systems of Breeding, Plant Breeding, Animal Breeding and more. At nearly 700 pages, this massive text is the most complete book of its kind and will be found to be a valuable resource to breeders of of all types of livestock and farm animals, as well as plant breeders. Note: This edition is a perfect facsimile of the original edition and is not set in a modern typeface.

Book Description
This newly updated and revised volume of the Encyclopedia of Sustainability Science and Technology (ESST) details the role of Animal Breeding and Genetics in the sustainability of animal agriculture. The volume covers scientific principles and applications includes the current science used to advance cattle, poultry, swine,sheep, and equine populations, as well as the future role of techniques such as gene editing. International leaders in the field explain foundational concepts such as heritability, the covariance between relatives, statistical approaches to predicting the genetic merit of individuals, and the development and advancement of molecular techniques to elucidate changes in the DNA sequence that underly phenotypic variation. The use of genetic-based tools to improve animal agriculture and meet consumer demands across species is treated in detail. Readers will gain an understanding of how global livestock producers have implemented advanced genetic selection tools and used them to improve reproduction, production, efficiency, health, and sustainability. The interactions of genetics and production environments, and the genetic components of the complex interactions among animals are also discussed. The future of Animal Breeding and Genetics, including the challenges and opportunities that exist in feeding a growing world population, are addressed.
