| 摘 要： | 为确定放牧条件下新疆褐牛的适宜补饲量,试验选取新疆褐牛泌乳牛32头,随机分为4组,每组8次重复,分别补饲0、2.5、5.0、7.5 kg/(d.头)。结果表明:在放牧条件下,补饲可以提高已过泌乳高峰期新疆褐牛泌乳牛的产奶量,还可以提高牛乳中乳蛋白和乳糖的含量。在该试验条件下,新疆褐牛的适宜补饲量为2.5 kg/(d.头)。

| Abstract: | To determine the appropriate quantity of supplementary feeding of Xinjiang brown cattle under natural grazing,32 Xinjiang brown cattles were selected and randomly divided into 4 groups with 8 replicates per group,which were fed with supplementary feeding by 0,2.5,5.0 and 7.5 kg per head everyday respectively.Results showed that the supplementary feeding could increase milk production of Xinjiang brown cattle under general grazing pasture conditions when Xinjiang brown cattle was after high lactation period,... |
