Comparison of Effect of "Niuyangzhuang"and "Niuyangfei"on Liveweight Gain of Han-Sheep with Small-tail

选用本地小尾寒羊60只,随机分为试验1组、试验2组、对照组3组,每组20只。试验1组在饲喂基础日粮中每只添加“牛羊壮”20g;试验2组在同等条件下,每只添加“牛羊肥”20g;对照组只喂基础日粮。试验表明,在试验期间,试验1组比试验2组平均多增重3.55kg,试验1组比试验2组经济效益多增28.98元。

60 Native Hart-sheep with small-tail were randomly divided into three groups-control group （n = 20）, test groupl （n = 20） and test group 2 （n = 20）. The Han-sheep with small-tail in the control group were fed with basal ration; the one in the test group 1 and the test group 2 were fed with basal ration added 20 “Niuyangzhuang”and “Niuyangfei”additive respectively. The results of test showed that the average liveweight gain of Han-sheep with small-tail in the test group 1 was 3.55kg more than that in the test group 2.And the economic benefit in the test group 1 was 28.98 yuan more than that in the test group 2.
