摘要
为研究中草药添加剂对围产期奶牛泌乳性能和乳品质的影响,中草药饲料添加剂在奶牛养殖生产中的推广应用奠定基础,将30头健康围产期奶牛随机分成对照组和中草药饲料添加剂组,对照组饲喂基础日粮,中草药饲料添加剂组在基础日粮中添加200 g/d·头的中草药制剂,测定日均产奶量、日均采食量、料奶比、乳脂率、乳蛋白率、乳糖率、乳干物质率等检测项目。结果显示,中草药饲料添加剂组与对照组相比较,每头试验奶牛的日均采食量提高6.88%(P<0.05),日均产奶量提高10.98%(P<0.05),乳脂率提高7.86%(P<0.05),乳蛋白率提高5.25%(P<0.05)。中草药饲料添加剂可显著提高围产期奶牛的采食量和产奶量,显著提高乳样中的乳脂率和乳蛋白率,提高围产期奶牛的泌乳性能和乳品质。
In order to study the effect of Chinese herbal medicine additive on milk performance and milk quality of periparturient dairy cows,and to lay a foundation for the popularization and application of Chinese herbal medicine additive in dairy cattle production,thirty healthy perinatal cows were randomly divided into control group and Chinese herbal medicine feed additive group.The control group was fed with basal diet,and the Chinese herbal medicine feed additive group was fed with 200 g/d Chinese herbal medicine preparation,the daily average milk yield,daily average feed intake,feed-milk ratio,milk fat ratio,milk protein ratio,lactose ratio and dry matter ratio were determined.The results showed that compared with the control group,the average daily feed intake,milk yield and milk fat percentage of each experimental cow increased by 6.88%(P<0.05),10.98%(P<0.05)and 7.86%(P<0.05),respectively,the percentage of milk protein increased by 5.25%(P<0.05).The results showed that Chinese herbal medicine feed additive could significantly increase the intake and milk yield of periparturient cows,increase the milk fat and milk protein in milk samples,and improve the milk performance and milk quality of periparturient cows.
