【Abstract】 Focuses on the variation resources and change Principles of Toggenburg dairy goat udder characters. Some important genetic parameters are also calculated. The function and numbers of udder gland are discussed for milk performance. The breeding weight of udder and its relative characters are compared. Udder characters based on measurement in breeding is proposed here. Udder characters taken as selective object presents more efficent effect.更多还原
