Abstract

This study was conducted to research the effects of different ratios of Bacillus licheniformis and Bacillus subtilis on performance, anti-oxidation property and cecal microflora of Partridge shank chicken. The purpose of this study was to get the best supplemental ratio. Six hundred Partridge shank chickens were randomly allocated into 6 groups with 4 replicates of 25 chickens each. Chickens in control group fed a basal diet; the other 5 groups were fed the basal diet supplemented with different ratios of Bacillus licheniformis and Bacillus subtilis. The proportions of each group were 0.50%:0.50%,0.33%:0.66%,0.25%:0.75%,0.66%:0.33%, and 0.75%:0.25%, respectively. Experimental period was 56 days. The results indicated that the body weight and average daily gain of chicken in group Ⅴ were significantly increased compared with the other groups (P<0.05), the average daily feed intake and ratio of feed to gain in group Ⅴ were significantly decreased compared with the other groups (P<0.05), and the mortality of group Ⅴ was the lowest (P<0.05). In group Ⅴ, total antioxidant capacity (T-AOC), total superoxide dismutase (T-SOD) and glutathione peroxidase (GPx) abilities in plasma were significantly improved (P<0.05), and the content of malon dialdehyde (MDA) in plasma was significantly declined (P<0.05). When the compound Bacillus in ratio of 0.66%:0.33% supplementation, the number of Lactobacillus in cecum was significantly increased (P<0.05), and the number of Escherichia coli, Enterococcus and Staphylococcus was significantly declined than those in the control group (P<0.05). In conclusion, with 0.66%:0.33% compound Bacillus supplemented, the performance and anti-oxidation property are significantly improve, and intestinal microflora is enhanced, then mortality can be declined.
