Animal husbandry, also called animal science, stockbreeding or simple husbandry, is the agricultural practice of breeding and raising livestock. It has been practised for thousands of years, since the first domestication of animals. In more modern times, the cowboys of North America, charros of México, or vaqueros, gauchos, huasos of South America, and farmers or stockmen of Australia tend their herds on horses, all-terrain vehicles, motorbikes, in four-wheel drive (4WD) vehicles and helicopters, depending on the terrain and livestock concerned. Today, herd managers often oversee thousands of animals and many staff. Farms, stations and ranches may employ breeders, herd health specialists, feeders, and milkers to help care for the animals. Techniques such as artificial insemination and embryo transfer are frequently used, not only as methods to guarantee that females are bred, but also to help improve herd genetics. The uniqueness of this book hence lies in the author's way of reconstructing the chapter under review by delving deep into the areas of the subject. The book will be useful not only to the students of Animal Husbandary but also to general reader.
