摘要
Abstract
According to the growth and development characteristics of cows, cows in perinatal period was divided into three stages： early perinatal stage（21 d before parturition）, late perinatal stage（21 d after parturition） and lactation（from the 21st day to the end of lactation）. And the feeding and management program was set up according to the growth characteristics and nutritional demands in three stages. The test results indicated that the feeding program in the dry period and perinatal period could decrease the incidence of retained placenta,milk fever,metritis and ketosis（P0.05）. The milk yield in test group increased 6.08 kg than that of control group, with significant difference （P0.05）. The milk compositions between the two groups had no significant change （P0.05）.关键词
