Drawing on numerous examples, this book examines in detail the various techniques used for genetic improvement of livestock, such as selection, crossbreeding and inbreeding. After a brief reminder of the foundations of genetics and the main factors to consider, as the effects of rearing environment on the animals, the authors describe the methods by emphasizing their advantages and disadvantages in the context of tropical and subtropical on how to use them to improve key traits of livestock. The importance of conserving the genetic diversity of local breeds of animals in hot regions is also emphasized. The book finally discusses the applications of recent advances in genomics and genetic improvement, including the development of molecular genetic markers at the DNA level.
This book will be a valuable tool for everyone - farmers, ranchers, agricultural technicians and consultants - whose activities or interests affecting the selection and improvement of livestock and livestock in the tropics. It will also serve as a reference for higher education and rural development programs.
