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.
