摘要： A feeding expriment was performed to investigate the effects of dietary supplementation with Brevibacillus brevis FJAT-1501-BPA fermentation on the growth performance, faecal microflora, faecal enzyme activities and blood parameters of weaned piglets. A total of 150 weaned piglets were randomly assigned to different treatments groups, which were fed the same basic diet supplemented with 10, 1, 0.1, 0.01 and 0 % B. brevis FJAT-1501-BPA fermentation. The results showed that a diet supplemented with 10 % B. brevis FJAT-1501-BPA fermentation could significantly increase the final body weight (P < 0.05) and decrease feed to gain ratio, which was 37.1 % lower than that of the control group. The addition of B. brevis FJAT-1501-BPA exhibited a trend of reducing the contents of the Escherichia coli, Lactobacillus and Salmonella compared with the control. During the 35 day experimental period, cellulase and protease activities were significantly increased by the dietary inclusion of the B. brevis FJAT-1501-BPA fermentation (P < 0.05). The cellulase activity for piglets fed diet containing 1 % B. brevis FJAT-1501-BPA fermentation, 21.8 U/g, was highest among the different treatments. The protease activity for piglets fed diet containing 10 % B. brevis FJAT-1501-BPA fermentation, 50.4 U/g, was highest among the different treatments. The amylase and hemicellulase activities for piglets fed diet containing 10 % B. brevis FJAT-1501-BPA fermentation were significantly higher than those on the control diet and other treatments (P < 0.05). Moreover, usage of feed dietary supplementation with B. brevis FJAT-1501-BPA had positive effects on levels of enzymes and minerals in blood. The alkaline phosphatase, alanine aminotransferase, Fe and Mg concentrations for weaned piglets fed diet containing B. brevis FJAT-1501-BPA fermentation were significantly higher than for those on the control diet (P < 0.05). Furthermore, concentration of IgG in serum was higher in weaned piglets fed diet containing 1 % B. brevis FJAT-1501-BPA fermentation compared to other treatments. These results indicated that feeding with B. brevis FJAT-1501-BPA has the potential to improve growth performance, faecal microflora, faecal enzyme activities and blood parameters of weaned piglets.
