JASB is a quarterly journal supported by Chinese As- sociation of Animal Science and Veterinary Medicine （CAAV）. The purpose of the joumal is to introduce Chinese research achievements of animal science and technology world over, and to strengthen academic communication between China and other countries. Subjects of the joumal are related widely of animal science such as： animal genetics and breeding, reproduction and physiology, biotechnology, nutrition and feed processing, environmental protection and grassland management.展开更多
