Outline
The objective of this study was to investigate the effects of dietary Moutai dried distiller’s grains （MDDG） on growth performance， nutrient apparent total tract digestibility （ATTD）， meat quality， serum immunity and antioxidant function， and intestinal health in growing-finishing pigs. And find out the suitable addition ratio. A total of 389 healthy Duroc × Landrace × Large White growing-finishing pigs with body-weights about 97 kg were randomly assigned to 3 dietary treatments consisting of 4 replicates with 31 to 34 pigs per replicate. The control group was fed a corn-soybean meal basal diet， the other two groups were fed the diet with 5% and 10% MDDG supplementation which replacing a portion of corn， soybean meal and wheat bran， with equal energy and nitrogen to the basal diet. The experiment lasted for 44 d. The results showed as follows： 1） Compared with the control group， the average daily feed intake and average daily gain in 10% MDDG group increased by 5.37% and 4.61%， respectively. In addition， the mortality rate in 10% MDDG group was decreased by 0.78% compared with the control group. The inclusion of 10% MDDG decreased the meat production cost by 0.02 yuan per kg， but the difference is not significant （P>0.05）. 2） A reduction in ATTD of crude protein， crude ash and calcium was observed with 10% MDDG inclusion （P<0.05）. MDDG inclusion up to 10% showed a decreasing trend of ATTD of phosphorus （P<0.1）. MDDG inclusion up to 10% had no significant effect on ATTD of crude fat （P>0.05）. 3） Compared with control group， inclusion of 5% or 10% MDDG significantly decreased the serum levels of endotoxin， diamine oxidase， and interleukin-6 （P<0.05）. The serum content of catalase tended to be increased in the 10% MDDG group （P<0.1）. 4） Compared with the control group， inclusion of 10% MDDG had a tendency （P<0.1） to reduce drip loss， while inclusion MDDG in the diet at 5% significantly increased （P<0.05） the redness a* value of longissimus dorsi muscle. 5） Dietary inclusion of 5% or 10% MDDG did not adversely affect the jejunum， liver and spleen histology. In conclusion， dietary inclusion of 10% MDDG increases the growth performance， fortifies intestinal barrier function， reduces inflammatory response， improves slaughter traits and meat quality of growing-finishing pigs， which enhances the economic benefits of swine feeding.
