Abstract

This study aimed to investigate the effects of dietary Bacillus subtilis and Clostridium butyricum on growth performance, slaughter performance, serum biochemical indices and antioxidant capacity of Wulong goslings. A total of 200 healthy one-day-old Wulong geese with similar body weight were randomly divided into 4 groups with 5 replicates in each group and 10 geese in each replicate. Geese in group Ⅰ (control group) were fed a basal diet, geese in group Ⅱ were fed the basal diet supplemented with 250 mg/kg Bacillus subtilis, geese in group Ⅲ were fed the basal diet supplemented with 250 mg/kg Clostridium butyricum, and geese in group Ⅳ were fed the basal diet supplemented with 250 mg/kg Bacillus subtilis+250 mg/kg Clostridium butyricum. The experiment lasted for 4 weeks. The results showed as follows:1) compared with the control group, the final weight of geese of groups Ⅱ, Ⅲ and Ⅳ was increased by 7.78% (P<0.05), 3.12% (P>0.05) and 9.54% (P<0.05), respectively; the average daily gain was increased by 7.89% (P<0.05), 3.39% (P>0.05) and 10.18% (P<0.01), respectively; the feed to gain ratio was decreased by 4.96% (P<0.05), 1.65% (P>0.05) and 6.20% (P<0.05), respectively. 2) Compared with the control group, the percentage of breast muscle of geese of groups Ⅱ, Ⅲ and Ⅳ was increased by 2.10% (P>0.05), 2.80% (P>0.05) and 4.20% (P<0.05), respectively; the percentage of leg muscle was increased by 9.50% (P<0.05), 8.60% (P<0.05) and 10.86% (P<0.05), respectively; the percentage of abdominal fat was decreased by 7.74% (P<0.05), 5.81% (P>0.05) and 10.97% (P<0.05), respectively. 3) Compared with the control group, the serum total antioxidant ability of geese of groups Ⅱ, Ⅲ and Ⅳ was increased by 4.46% (P>0.05), 3.39% (P>0.05) and 12.33% (P<0.05), respectively; the serum total superoxide dismutase activity was increased by 4.94% (P<0.05), 3.30% (P>0.05) and 7.69% (P<0.01), respectively. In conclusion, dietary Bacillus subtilis and Clostridium butyricum can improve the growth performance, slaughter performance and antioxidant capacity of Wulong goslings, and the effects of combined use of the two bacteria is better than that of a single strain.
