Abstract

This study was conducted to evaluate the effects of complex-probiotics supplementation on growth performance, fecal microbiota and serum profiles of weaner piglets. Ninety-six (48 females and 48 males) piglets (Large White×Landrace) weaned at 35 to 37 days of age [the average body weight was (9.70±0.88) kg] were selected and divided into 3 groups with 4 replicates per group and 8 piglets per replicate. The piglets in each group were fed one of 3 diets: a basal diet without antibiotics and probiotics (control), the basal diet supplemented with complex-probiotics (including Bacillus licheniforms, Bacillus subtilis and Lactobacillus plantarum, probiotics group) or the basal diet supplemented with kitasamycin (antibiotic group). The trial lasted for 35 days. The results showed as follows: 1) during the whole experiment period, no differences among three groups in average daily feed intake (ADFI) and average daily gain (ADG) were detected (P>0.05). 2) On day 35, the number of E. coli in feces of the piglets fed the diets supplemented with complex-probiotics was significantly lower than that fed the other diets (P<0.05). 3) On day 14, compared with the control group, the supplementation of complex-probiotics significantly increased serum albumin content (P<0.05), but significantly decreased the ratio of albumin to globulin in serum (P<0.05). On day 35, compared with antibiotic group, serum globulin content of piglets fed the diets supplemented with complex-probiotics was significantly increased (P<0.05) and the ratio of albumin to globulin in serum was significantly decreased (P<0.05). During the whole experiment period, the contents of albumin, urea nitrogen and creatinine, and the activity of alkaline phosphatase in serum were unaffected by the supplementation of complex-probiotics (P>0.05). 4) On day 14, the supplementation of complex-probiotics significantly increased serum IgM content compared with the control group (P<0.05). On day 35, the supplementation of complex-probiotics significantly increased serum IgA content compared with antibiotic group (P<0.05). These results suggest that complex-probiotics supplementation of Bacillus licheniforms, Bacillus subtilis and Lactobacillus plantarum decreases the number of E. coli in feces and enhances immune responses in piglets.
