奶牛产后应用灌服包效果研究
Effectiveness of oral drenching packets on the recovery and performance of postpartum dairy cows
目的 评估灌服包在奶牛产后应用的效果,为其在产后保健中的推广应用提供理论依据。 方法 选取健康产后奶牛162头,随机分为试验组和对照组,每组各81头,试验组在产后1 h内一次性灌服含有灌服包的灌服制剂(10 kg温水),对照组灌服含有红糖麸皮水和丙二醇的同等量温水。记录各组奶牛的产房停留时间、发病情况、产奶性能、产后首次发情时间及配种情况。 结果 与对照组相比,试验组奶牛产后15 d内转出产房的比例提高了15%~20%,围产期发病率降低了5%~18%,达到产奶高峰的时间缩短7~16 d,首次发情及配种时间提前7~15 d。 结论 产后应用灌服包可有效促进奶牛康复,降低疾病发生率,提高生产性能,具有良好的应用前景。
Objectives The effectiveness of oral drenching packets in postpartum dairy cows were evaluated to provide theoretical support for its promotion and application in the health care of postpartum dairy cows. Methods 162 healthy postpartum dairy cows were randomly divided into an experiment group and a control group, with 81 cows in each group. The dairy cows in the experiment group received a one-time oral drench of 10 kg of warm water mixed with a drenching packet within 1 hour after calving, while that in the control group received the same volume of warm water mixed with brown sugar, wheat bran, and propylene glycol. The duration of stay in the calving pen, incidence of diseases, lactation performance, time to first estrus, and insemination data in each group of dairy cows were recorded. Results Dairy cows in the experiment group had a 15%-20% higher rate of leaving the calving pen within 15 days postpartum, a 5%-18% lower incidence of peripartum diseases, a 7-16 days earlier attainment of peak milk yield, and a 7-15 days advancement in both first estrus and insemination time compared with that in the control group. Conclusions The application of oral drenching packets in postpartum dairy cows can effectively promote the recovery of cows, reduce the incidence of diseases, improve lactation performance, and have promising prospects of application.
