摘　　要：为进一步研究尿素糖浆营养舔砖对放牧牦牛和藏羊的补饲效果,2018年2—3月,从某养殖场选择1岁的藏羊和牦牛各20头,应用随机划分的原则,将20头牦牛和藏羊划分成2个组别,分别命名为试验组和对照组,试验组牦牛和藏羊分别选择使用尿素糖浆营养舔砖进行补饲,对照组藏羊和牦牛选择传统养殖模式进行放牧养殖。试验结束后,对比2个组别的体重增加情况。通过对藏羊和牦牛进行2月的补饲试验,得出试验组藏羊和牦牛补充尿素糖浆,营养舔砖能保障藏羊和牦牛体况维持相对平衡,有效缓解冬季牧草不足所造成的膘情下降的现象。试验组和对照组的牦牛藏羊体重变化情况相比对比差异性极其显著(P<0.01),季节牦牛和藏羊养殖中,通过适量添加尿素糖浆营养舔砖,能有效缓解藏羊和牦牛体重流失的情况,保障机体养分来源充足,确保藏羊和牦牛能安全越冬,在今后养殖中值得进一步推广应用。In order to further study the feeding effect of urea ayrup nutrient lick brick on grazing yaks and Tibetan sheep,20 Tibetan sheep and yaks were selected from a farm in December 2018,twenty yaks and Tibetan sheep were divided into two groups,which were named as test group and control group.Yak and Tibetan sheep in test group were fed with urea syrup nutrient lick brick respectively,the control group of Tibetan sheep and yaks were selected for the traditional breeding mode.At the end of the trial,weight gain was compared between the two groups.According to the supplementary feeding experiment of Tibetan sheep and yak in February,it is found that Tibetan sheep and yak in the test group can keep the relative balance of Tibetan sheep and yak iron ore by supplementing urea syrup and licking bricks,to effectively alleviate the lack of winter pasture caused by the decline in the phenomenon of standard.There was a significant difference in the change of body weight between the experimental group and the control group(P<0.01).In the breeding season of yak and Tibetan sheep,by adding urea syrup to the nutrient bricks,it can effectively alleviate the loss of body weight of Tibetan sheep and yak,ensure adequate nutrition source of body and ensure the safe winter of Tibetan sheep and yak.
