title: Effects of corn distillers dried grains with solubles on performance, oxidative status, intestinal immunity and meat quality of Chinese Yellow broilers.
abstract: The study assessed the effects of different dietary levels of corn distillers dried grains with solubles (DDGS) on performance, oxidation status, intestinal immunity and meat quality in Chinese Yellow broilers aged from 1 to 63 days. Lingnan male hatchings (1440) were randomly assigned to six treatments, each consisting of six replicates of 40 birds. The basal diet (I) was a typical corn-soya bean ration while the experimental diets (II to VI) partially substituted corn DDGS for soya bean meal. The level of substitution in starter, grower and finisher diets was as follows: II, 2%, 4% then 6%; III, 4%, 8% then 12%; IV, 6%, 12% then 18%; V, 8%, 16% then 24%; VI, 10%, 20% then 30%. Average daily feed intake and feed-to-gain ratio increased as linear responses to corn DDGS substitution from 1 to 21 days (p < 0.001). The plasma content of triglycerides and liver content of malondialdehyde increased as linear responses to corn DDGS substitution (p < 0.05). There was a linear decrease (p < 0.001) in jejunal abundance of IL-6 transcripts, with a substantial reduction to approximately 25% those of broilers fed the control diet, and a quadratic effect existed for secretory immunoglobulin A (sIgA) (p < 0.001). In addition, increased dietary corn DDGS caused favourable changes in selected functional properties of the meat: drip loss at 24 and 96 h increased as linear response to corn DDGS substitution (p < 0.001). Further, meat colour L* values decreased and a* values increased linearly in response to increasing corn DDGS (p < 0.05). In conclusion, diet IV (6%, 12% then 18% corn DDGS) in Chinese Yellow broiler diets had no negative effects on performance, antioxidant capacity and meat quality. This level of inclusion also appeared to promote sIgA secretion and enhance anti-inflammatory status.
