The major histocompatibility complex (Mhc) is one of the few identified gene systems in domestic animals that is associated with quantitative traits such as disease resistance, immune response, growth, and reproduction. As knowledge of this important system increases, we move closer toward the reality of genetic enhancement of animal welfare and production efficiency. This book represents the current state of knowledge on the Mhc of agriculturally important animals and explores the latest advances in technology. For the first time, the unique findings of recent Mhc research are presented in a...
