To exploring the effects of probiotics on growth performance, immune function, blood biochemical indicators and cecal flora of broilers, 5 native experimental probiotics (Bacillus coagulans, Lactobacillus fermentum, Bacillus subtilis, Bacillus licheniformis and Enterococcus faecalis) were isolated and purified. Broilers Fufeng and Sanhuang were divided: 5 single experimental probiotic groups, 1 mixed experimental probiotic group (Lactobacillus fermentum, Bacillus subtilis, Bacillus licheniformis, Enterococcus faecalis), commercial probiotics group and negative control group. Each group had 10 replicates of each type of broilers. The experimental probiotics were added to broiler’s diet during experimental period. The growth performance was measured on 21d, 42d and 77d while the immune function, blood biochemical indexes and cecal flora were measured on 77d. The growth performance results showed that experimental probiotics could effectively increase the FCR and BWG (P |
