Abstract

This experiment was conducted to investigate the effects of Lactobacillus plantarum and non-starch polysaccharide (NSP) compound enzymes on growth performance, fecal microbial flora and serum parameters of weaned piglets to achieve the purpose of substituting antibiotics. According the single-factor completely randomized design, one hundred and ninety-two 28-day-old healthy weaned piglets with average body weight of (7.15±0.36) kg were randomly divided into 4 groups with 6 replicates per group and 8 weaned piglets per replicate. The weaned piglets in control group (CT group) were fed the diet supplemented with 40 mg/kg bacitracin zinc, the others in the experimental groups were fed the diet supplemented with 1 g/kg Lactobacillus plantarum (PT group), 1 g/kg NSP compound enzyme (ZT group), 1 g/kg Lactobacillus plantarum+1 g/kg NSP compound enzymes (PZT group), respectively. The test lasted for 35 days. The results showed as follows: 1) no significant differences were found in final body weight, average daily gain, average daily feed intake and feed/gain of weaned piglets among all groups (P>0.05). 2) The numbers of Lactobacillus and E. coli and Lactobacillus/E. coli in faces of weaned piglets had no significant differences among all groups (P>0.05). However, the numbers of Lactobacillus and Lactobacillus/E. coli in faces of weaned piglets in PZT group were higher than those in CT group (0.05≤P<0.10), whereas the number of E. coil in faces of weaned piglets in PZT group was lower than that in CT group (0.05≤P<0.10). 3) The serum biochemical and immune parameters of weaned piglets had no significant differences among all groups (P>0.05). Thus, dietary Lactobacillus plantarum and NSP compound enzymes can promote the balance of intestinal flora, has benefit to piglet health, and to achieve the purpose of substituting antibiotics.
