| 摘 要： | 针对奶牛的生长发育特点,将围产期与产奶牛细分为3个阶段,即围产前期(产前21d到分娩)、围产后期(分娩到产后21d)、产奶期(产后21d到产奶结束),并根据3个阶段的生长发育特点和营养需求建立饲养管理程序。试验结果表明,干奶期和围产期饲养程序可以降低胎衣不下、产褥热、酮病和子宫炎的发病率(P<0.05),试验组产奶量比对照组高出6.08kg,差异显著(P<0.05),2组的乳成分没有显著变化(P>0.05)。 |

| 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(P<0.05). The milk yield in test group increased 6.08 kg than that of control group, with significant difference (P<0.05). The milk compositions between the two groups had no significant change (P>0.05). |
