Equine Color Genetics, Fourth Edition presents a detailed examination of the color variation in horses and donkeys and the genetic mechanisms that produce color variations. Thoroughly covers the basic colors in horses, including bay, chestnut, black, and brownDetails the genetic basis of the colors built from the basic coat color, including dilutions and white patterningProvides an explanation of genetic mechanisms that determine coat colorPresents a thorough revision and update, including new advances in molecular genetics, biochemistry, molecular mechanisms, genetic loci, coat colors before domestication, and moreOffers a new introduction describing the principles of genetics and genomics research to help outline how knowledge is discovered and to assist the reader in understanding concepts covered in the book

For animal breeders colour coat genetics is one of the fundamental elements of breeding, along with health and conformation. Breeders need to know about colour coats for showing purposes and where the fibre is used in industry, for example sheep and alpaca wool.The science behind breeding for genetic traits is complex because of dominant and recessive traits. Because animals inherit two alleles for the base coat colour, it is possible that their phenotype, or visual appearance, does not reflect their underlying genotype.This book is a practical guide for breeders on the biology behind colour coats in large animals directing breeders on how to implement breeding strategies to achieve desired results.

Breeds are fascinating entities. They depend on individual breeders for their continuing existence. Although breeders may come and go, each of them is important and has the potential to make positive contributions to the breed.Multiple factors can guarantee breeders long-term successful management. These include biological aspects, consistent market demand, and the important and sometimes politically charged role of breed associations as the main advocates for breeds today.Strategies for success have been detailed in the first and second editions of Managing Breeds for a Secure Future. The third edition explores this further, providing more strategies that can assure long-term survival for breeds of livestock, poultry, and dogs.Managing Breeds for a Secure Future Third Edition is re-organized to flow better, and has additional chapters on specific protocols for maintaining breeds. It also delves more deeply into rescuing rare populations, through both theory and practice. Updates to the new edition include: biological issues, population analysis, pedigree-based analyses, managing a genetic defect, and specific rescue principles and practices.

Breeding Better Dogs: Genetics and Reproduction delves into the biology of managing reproduction in dogs, from mating to whelping and the first few weeks of life. It also delves into the genetic management of dog breeds and selection procedures to aid breeders in producing sound, useful dogs. The book includes:details of managing the genetic structure of breeds and genetic management of individual breeding programsdetails of managing dogs that are used for breedingdetails of mating dogs, managing pregnancies and whelpingThis book is an excellent resource for dog breeders. Providing an accessible approach to a complex subject, Breeding Better Dogs breaks down into digestible chunks the essential information for understanding the subject at a broad level.

Mason's World Encyclopedia of Livestock Breeds and Breeding describes breeds of livestock worldwide as well as a range of breed-related subjects such as husbandry, health and behaviour. This definitive and prestigious reference work presents easily accessible information on domestication (including wild ancestors and related species), genetics and breeding, livestock produce and markets, as well as breed conservation and the cultural and social aspects of livestock farming. Written by renowned livestock authorities, these volumes draw on the authors' lifelong interest and involvement in livestock breeds of the world, presenting a unique, comprehensive and fully cross-referenced guide to cattle, buffalo, horses, pigs, sheep, asses, goats, camelids, yak and other domesticants. Volume 1: contains asses, camelids, cattle, goats, horses and pigs Volume 2: contains sheep, water buffalo, yak and other livestock Coverage: Breed descriptions: including groups, types and varieties, history and links between groups, livestock products and trends for creating new breeds Wild species: ancestral and relatives, potential domesticants and hybridization Humans and breeds: spread of domestication, transhumance and pastoralism, social and cultural influences, suitability of different groups for different human purposes Genetics and Conservation: a dedicated section and glossary of terms Placing breeds in a practical agricultural context, this two volume encyclopedia will be of great value to agriculturalists, breeders, geneticists, biologists, rural historians, conservationists, ecologists, and all those who are interested in the rich diversity of livestock breeds.
