This experiment was conducted to investigate the effects of compound microorganism fermented corn gluten meal on growth performance, intestinal microflora number and antioxidant capacity of broilers. One hundred and fifty 7-day-old broilers were randomly assigned to 3 groups with 10 replicates per group and 5 broilers per replicate. The broilers in the control group were fed a basal diet, and the broilers in other groups were fed the basal diet supplemented with 5% and 10% fermented corn gluten meal, respectively. The experiment lasted for 49 days. The results showed that compared with the control group:1) dietary supplemented with 5% and 10% fermented corn gluten meal significantly increased the average daily gain (ADG) and average daily feed intake (ADFI) of broilers (P<0.05), and dietary supplemented with 10% fermented corn gluten meal significantly decreased the ratio of feed to gain (F/G) (P<0.05); 2) dietary supplemented with 10% fermented corn gluten meal significantly increased the liver index, kidney index at 18 days of age and kidney index, thymus index at 56 days of age (P<0.05 or P<0.01); 3) dietary supplemented with 10% fermented corn gluten meal significantly decreased the caecal Escherichia coli number at 28 days of age (P<0.01), and dietary supplemented with 5% and 10% fermented corn gluten meal significantly increased caecal Lactobacillus number at 28 and 56 days of age (P<0.05); 4) dietary supplemented with 5% and 10% fermented corn gluten meal significantly increased the capacity of antisuperoxide anion free radical and restraining ability to hydroxyl free radical in serum (P<0.01), and significantly decreased the content of serum malonaldehyde content at 28 days of age (P<0.01). It is concluded that dietary supplemented with fermented corn gluten meal can promote growth, optimize the structure of intestinal microflora, and improve antioxidant capacity of broilers.
