摘 要:[目的]甘肃省的饲料资源现状是粗饲料资源丰富,蛋白质饲料相对不足,为了解决草食畜养殖过程中蛋白质饲料不足的问题,[方法]通过对育肥牛、奶牛、牦牛等补饲尿素糖浆饲料舔块,增加蛋白质采食量,[结果]显示,采食尿素糖浆饲料舔块后,育肥牛日增重增加,奶牛产奶量提高,繁殖母牛怀孕率提高,读牛初生重提高。[结论]补饲一定数量的尿素糖浆饲料舔块,在粗放饲养和低精饲料条件下生产性能明显提高。To solve the problem of protein shortage in herbivores production in Gansu province, urea syrup were added to the dietary of finishing beef, dairy cow and yak to increase crude protein intake. It was found that when the urea syrup was added to feed, average daily gain, milk yield amd pregnant rate of finishing beef, dairy cow and reproduction cows were raised and birth weight of calves were increased, i.e. supplementation of urea syrup could improve the production performance of herbivores.
