Abstract

This experiment aimed to study the effects of dietary coated sodium butyrate on growth performance, serum biochemical indices, nutrient apparent digestibility and fecal microflora population of weaning piglets. A total of 128 healthy 28-day-old Large White weaning piglets with an average body weight of (6.37±0.11) kg were randomly allocated to 4 groups with 4 replicates of 8 piglets. The piglets in control group were fed a basal diet, and those in the treatment groups were fed the basal diet with different supplemental levels of coated sodium butyrate (500, 1 000, 1 500 g/t). The experiment lasted 28 days. The results showed as follows: 1)compared with the control group, dietary supplemented with 1 000 and 1 500 g/t coated sodium butyrate significantly elevated the final weight and the average daily gain of weaning piglets at 1 to 28 days, and significantly decreased the feed/gain of weaning piglets at 1 to 14 days and 1 to 28 days (P<0.05). 2)Compared with the control group, dietary supplemented with 1 000 and 1 500 g/t coated sodium butyrate significantly increased the serum total protein (TP), glucose (GLU), immunoglobulin A (IgA), immunoglobulin G (IgG) contents of weaning piglets (P<0.05), and significantly reduced the serum urea nitrogen (UN) content of weaning piglets (P<0.05). 3)Compared with the control group, dietary supplemented with 1 000 and 1 500 g/t coated sodium butyrate significantly increased the apparent digestibility of crude protein and ether extract (P<0.05). 4)Compared with the control group, dietary supplemented with 1 000 and 1 500 g/t coated sodium butyrate significantly reduced the number of Escherichia coli (P<0.05), and significantly increased the number of Lactobacilli (P<0.05). In conclusion, dietary supplemented with coated sodium butyrate can promote the growth of weaning piglets and immunity, increase the apparent digestibility of nutrients, and improve the balance condition of intestinal flora. Under the conditions of the present experiment, the optimal supplemental level of coated sodium butyrate in the weaning piglets' diet is 1 000 g/t.
