Abstract

This experiment was conducted to study the effects of dietary yeast cell wall polysaccharide on growth performance and small intestinal mucosa morphology of weaned piglets. One-factor design was used and one hundred and eighty piglets with similar genetic background, health condition, parity and body weight weaned at 21 days of age were randomly divided into four groups with five replicates in each group and nine piglets in each replicate. Pigs in four groups were fed control diet, 0.15%, 0.30% and 0.45% yeast cell wall polysaccharides diets, respectively. The experiment lasted for 21 days. The results showed as follows:1) compared with the control group, diets added with yeast cell wall polysaccharide significantly increased average daily gain (ADG) and average daily feed intake (ADFI) (P<0.05), and had a trend to decrease diarrhea incidence and the ratio of feed to gain of weaned piglets, although there were no significant differences (P>0.05). 2) Compared with the control group, diets added with yeast cell wall polysaccharide significantly increased the ratio of villus height to crypt depth (V/C) in jejunum of weaned piglets (P<0.05), and diet added with 0.45% yeast cell wall polysaccharide significantly increased villus height in jejunum and V/C in duodenum of weaned piglets (P<0.05). Accordingly, the yeast cell wall polysaccharide can enhance the growth performance, and improve the small intestinal mucosa morphology of weaned piglets. By considering the growth performance, small intestinal mucosa morphology and economic cost, 0.30% yeast cell wall polysaccharide is an optimum addition level in the piglet diet.

Key words： yeast cell wall polysaccharide; weaned piglets; growth performance; small intestinal mucosa morphology
