葡萄籽粉替代玉米对成年母羊体重和经济效益的影响

Effect of Grape Seed Powder Replacing for Corn on the Weight and Economic Benefit of Adult Ewes

本试验旨在研究日粮中添加不同剂量葡萄籽粉替代玉米对成年母羊体重和经济效益的影响。试验选取年龄相近(15～16月龄)、健康状况良好的成年母羊32只,根据体重相近原则随机分为4组,对照组饲喂基础日粮,试验Ⅰ、Ⅱ和Ⅲ组分别用葡萄籽粉替代基础日粮中7%、14%和21%玉米。结果表明,试验各组间羊增重差异不显著(P>0.05),但试验Ⅰ组平均日增重比对照组提高了14.50%,且经济效益比对照组平均提高了37.74%。提示,本试验中在基础日粮中使用葡萄籽粉替代7%玉米对成年母羊的增重效果和经济效益最佳。

The research was conducted to study the influence of different doses of grape seed powder replacing for corn on weight and economic benefi of adult ewes. 32 adult sheep with similar age （15 to 16 months） and in good health were randomly divided into 4 groups according to the principle of similar weight. The control group was fed the basal diet, the testⅠ,Ⅱ and Ⅲ groups added different doses of grape seed powder replacing for 7%, 14% and 21% corn in the basal diet. The results showed that the test Ⅰ,Ⅱ and Ⅲ groups were no significantly difference compared with the control group in weight gain （P〉0.05）, the average weight of test Ⅰ group increased 14.50%, and the economic benefit of test Ⅰ group increased 37.74%. In short, adding grape seed powder replacing for 7% corn in the basal diet was the best for weight gain and economic efficiency of adult sheep in this research.
