Book excerpt: Some skill, some luck and lots of fun: sheep colour genetics is like a game of cards! This book explains the rules of the game. Assuming no previous knowledge, the book uses a game of cards to visualise the rules that govern colour genetics, introducing terminology on the way. What are genes and alleles? What is the phenotype of a sheep? What the genotype? The reader is introduced to agouti-pattern, base colour, and spotting and strategies are shown to identifiy them in the reader's own flock. This knowledge is expanded to show how it can be used to plan breeding for certain colours. More genes that influence colour are introduced later in the book and thought is given to preserving diversity within a breed while strategically increasing the presence of desirable traits in a flock. The book focuses on practical aspects. How to identify genotypes? Which animals should be used for test breeding? How can the knowledge be used for individual goals? Written by a molecular biologist and science communicator and co-written by a professional editor of scientific textbooks - both of them breeders of coloured sheep - this book uses an easily understandable approach to explaining colour genetics.

Book excerpt: Sheep Breeding, Second Edition covers sheep breeding in its widest context through a collection of papers about sheep breeding from experts in the field across the globe. The book incorporates sections composed of general review articles and important research findings on the structures and objectives of national sheep industries from many of the major sheep-producing areas of the world. The text also discusses the genetic selection and breed improvement; stud breeding and cooperative breeding schemes; reproduction in the ewe; and male reproduction and artificial insemination. The monograph is recommended for those who wish to learn different techniques and practices in raising and breeding sheep, especially those who are new in the field. The book is also for those who wish to conduct research that would help improve raising and breeding sheep.

Book excerpt: The third volume in the Institute of Animal Health (IAH) Biology of Animal Infections Series, Bluetongue discusses one of the most economically important diseases of domesticated livestock. Affecting primarily sheep particularly the improved mutton and wool breeds, it is now endemic in Africa, India, the Middle and Far East, Australia and the Americas, and over the last six years has caused a series of outbreaks throughout the Mediterranean region and central Europe. Bluetongue represent a paradigm not only for the other orbiviruses (such as African horse sickness virus, which shares the same vector species) but also for other insect transmitted diseases, including those of humans. The only single definitive work that provides both historical and up to date data on the disease Describes the latest developments in epidemiological modelling, molecular epidemiology and vaccine development, as well as explaining the current global epidemiology of the disease Outlines the importance and possible mechanisms of overwintering, and the impact of global warming on the vectors and virus distribution
