中国猪的优良种性及其对世界养猪业的贡献

The Chinese pig breeding has a long history. 9000-6000 years ago, the Chinese ancestors already tamed and trained the local wild boars. The Chinese ancient people paid great attention to the selective work of pigs. So, as early as in the Han Dynasty fine germ-plasm of Chinese pigs was well-known at home and abroad. During the Han Dynasty, the Small-ear pig of South China was introduced into Da chin country (Roman empire)to be bred into the ancient Roman pigs. By the seventeenth and eighteenth centuries, the Chinese pigs(Guangdong pig species) were introduced into Britain, the USA, etc. Then they. played an important role in the improvement of those countries' pig species.In recent years, for lack of good species resource some countries with developed animal husbandry have paid great attention to Chinese pig species and introduced them to many western countries. They have got the encouraging effects. Therefore nowadays France, Britain, Japan,U. S. A. and Netherlands are all carrying out the resources on pigs and hope to make greater contributions to the improvement of the world's pig species.
