ABSTRACT
Biotechnology development is rapid, broad application fields, including medicine, food, agriculture and animal husbandry, fishery, chemical industry, energy, metallurgy, marine industry and environmental protection, etc. Animal husbandry is an important field of biotechnology. Genetic engineering as the core, including cell engineering, enzyme engineering and fermentation engineering of biotechnology with the progress of modern animal husbandry and veterinary have close relations, become an important part of the animal husbandry technology revolution. These technology research, development and application of excellent germ plasm resources conservation and utilization of livestock, breed improvement, improve the feed nutrition value and fast and exact diagnosis and treatment of diseases provide a broad prospect. The establishment of the modern biological technology, pioneered a new way of livestock production.
