Abstract

This experiment was conducted to investigate effects of dietary Lactobacillus plantarum, buckwheat flavone and their compounds on growth performance, nutrient digestibility and serum indices of weaned piglets. Fifty 35-day-old weaned piglets weighed (7.85±0.67) kg were selected and assigned into 5 groups with 10 replicates per group and 1 pig per replicate. Piglets in negative control (NC) group were fed a basal diet, and others were fed basal diets supplemented with 40 mg/kg colistin sulfate (positive control group, PC group), 1×109 Lactobacillus plantarum (LP group), 40 mg/kg buckwheat flavone (BF group) and both 1×109 Lactobacillus plantarum and 40 mg/kg buckwheat flavone (LB group). The experiment lasted for 24 days. The results showed as follows:1) the average daily gain of piglets at 1 to 28 days in BF group was significantly higher than that in NC group and PC group (P<0.05), and increased 52.74% and 34.14%, respectively. 2) The nutrient digestibility of piglets in NC group was significantly lower than that in other groups (P<0.05), the digestibility of total energy, dry matter, organic matter and phosphorus of piglets in LB group was significantly higher than that in other groups (P<0.05). 3) The contents of total protein, albumin, urea nitrogen, glucose, free fatty acids, immunoglobulin G, immunoglobulin A and immunoglobulin M in serum of piglets in BF group were significantly higher than those in NC group (P<0.05). The activities of total antioxidant capacity, superoxide dismutase, glutathione peroxidase, catalase in serum of piglets in LP group were significantly higher than those in NC group and PC group (P<0.05), however, the serum malondialdehyde content was significantly lower than that in NC group and PC group (P<0.05). The results indicate that Lactobacillus plantarum can improve the antioxidant ability while buckwheat flavone can increase the growth performance and immune ability of weaned piglets. Moreover, combination of Lactobacillus plantarum and buckwheat flavone can promote the diet nutrient digestibility.
