摘要： 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。

Abstract: In this study,the effects of DDGS(distillers dried grains with solubles) on growth performance and serum biochemical indexes were investigated to discuss in finishing pigs. One hundred and twenty Duroc × Landrace × Large white pigs with 60 kg body weight were randomly allotted into 5 groups. The control group was fed with corn-soybean meal basal diet,and test I,II and III were fed with the DDGS volume of 8%,16%,24%,test Ⅳ was fed with the DDGS volume of 24% + compound enzyme(amount: 160 mg /kg), the experiment lasted for 45 days period. The results showed that,compared with control group,the ADG of test I,test II,test III and Ⅳ were decreased by 7. 44%,13. 69%,28. 04% and 19. 76%,and there was a significant difference between the control group and test I,II and Ⅳ(P ＜ 0. 05) ; The ADFI of test I,II,III and Ⅳ were decreased by 3. 53%,6. 01%,15. 90% and 8. 48%,and there was a significant difference between the control group and test III and Ⅳ (P ＜ 0. 05) ; The F /G of test I,II,III and Ⅳ were increased by 4. 14%,8. 88%,17. 76% and 13. 61%,and there was a significant difference between the control group and test III and Ⅳ(P ＜ 0. 05). On 45 d,the serum total cholesterol,triglycerides,phosphorus,AST and ALT concentration between each groups were no significant difference (P > 0. 05). The result suggested that there was no significant effect on growth performance when 8% or 16% DDGS was used in finishing pigs diet.
