Abstract:

为研究玉米-豆粕型饲粮中使用DDGS对肥育猪生长性能和血清生化指标的影响,选择120头体重约60kg的杜×长×大三元杂肥育猪随机分为5组,对照组饲喂玉米-豆粕型基础饲粮,试验I组、II组、III组DDGS使用量分别8%,16%,24%,试验IV组添加24%DDGS+复合酶(添加量:160mg/kg),进行为期45d的饲养试验。结果表明,与对照组比较,各试验组平均日增重分别降低7.44%,13.69%,28.04%和19.76%,其中试验II、III和IV组差异显著(P<0.05);各试验组平均日采食量分别降低3.53%,6.01%,15.90%和8.48%,其中试验III和IV组差异显著(P<0.05);各试验组料重比分别提高4.14%,8.88%,17.76%和13.61%,其中试验III和IV组差异显著(P<0.05)。45d各组间血清总胆固醇、甘油三酯、血清磷、谷草转氨酶和谷丙转氨酶含量均无显著差异(P>0.05)。饲粮中DDGS使用量为8%和16%对肥育猪生长性能无显著影响。
