摘 要:为了研究不同饲料配方对徐淮山羊育肥效果的影响,试验选择健康、体重相近、3月龄徐淮山羊40只,随机分为2组,每组20只。对照组饲喂商品饲料,试验Ⅱ组饲喂自配饲料,预试期15 d,试验期60 d。结果显示,试验组比对照组平均日增重高10.29 g,增重率为9.00%(P<0.05);平均日采食量增加0.02 kg(P>0.05);料重比降低0.86(P<0.05);利润提高19.70%。说明试验组日粮配方饲喂徐淮山羊,不仅提高肉羊的育肥效果,还降低饲养成本,经济效益上升,有着较大的推广价值。In order to study the effect of different feed formulae on the fattening effect of Xuhuai goats,40 healthy xuhuai goats with similar weight and 3 months old were randomly divided into 2 groups with 20 goats in each group.Control group feeding commodity feed,feeding the mixed feed testⅡgroup,15 d pilot test period,60 d trial.The results showed that the average daily weight gain in the experimental group was 10.29 g higher than that in the control group,with a weight gain rate of 9.00%(P<0.05);Average daily feed intake increased by 0.02 kg(P>0.05);Material weight ratio reduction by 0.86(P<0.05);Profits rose 19.70 percent.The results showed that the diet formula of the experimental group not only improved the fattening effect of the mutton sheep,but also reduced the feeding cost and increased the economic benefit,which had great promotion value.
