Effects of three probiotic Bacillus on growth performance, digestive enzyme activities, antioxidative capacity, serum immunity, and biochemical parameters in broilers.
This study was conducted to evaluate the effects of three Bacillus strains on growth performance, digestive enzyme activities, antioxidative capacity, serum immunity, and biochemical parameters in broilers. A total of 360 one-day-old Ross 308 chicks were randomly allocated into four groups with three replicates per group (n = 30). The control group was fed a basal diet, whereas the other groups fed basal diet supplemented with either Bacillus subtilis natto or Bacillus licheniformis or Bacillus cereus (108  cfu/kg) for 42 days, respectively. The results revealed that the probiotic-treated groups markedly improved final body weight, daily weight gain, and the activities of trypsin, amylase, lipase and total protease (p < 0.05). Moreover, chicks fed probiotics had higher serum glutathione peroxidase activity and O2 - level, as well as hepatic catalase and superoxide dismutase activities, whereas malondialdehyde levels in serum and liver were reduced (p < 0.05). The significant increased IgA (p < 0.05) was observed in the probiotics groups as compared to the control group. In addition, dietary administration of probiotic strain markedly reduced the levels of serum ammonia, uric acid, total cholesterol, and triglyceride. Taken together, these three probiotic Bacillus showed beneficial effects on chickens with minor strain specificity.
