Effects of Yeast Cell Wall Polysaccharides on Intestinal Volatile Fatty Acids and Microbial Flora of Weaned Piglets
摘要
Abstract
An experiment was conducted to determine the effects of yeast cell wall polysaccharides on intestinal volatile fatty acids and microbial flora of weaned piglets. A total of one hundred and eighty piglets with similar genetic background, health condition, parity and body weight which weaned at 21 days of age were randomly allotted to 4 groups with 5 replicates each and 9 pigs in each replicate. Pigs in the four groups were fed control diet ( without adding yeast cell wall polysaccharide) , 0.15% yeast cell wall polysaccharide diet, 0.30% yeast cell wall polysaccharide diet and 0.45% yeast cell wall polysaccharide diet, respectively. The experiment lasted for 21 days. The results showed as follows: 1) compared with the control group, dietary supplementation of 0.15%, 0.30% and 0.45% yeast cell wall polysaccharides significantly increased colon acetic acid content of pigs ( P<0.05) , and 0.30% and 0.45% yeast cell wall polysaccharides also significantly enhanced the contents of propionic acid, butyric acid and total volatile fatty acids (TVFA) in colon (P<0.05), but there were no significant differences between both ( P>0.05) . 2) Compared with the control group, dietary supplementation of 0.15%, 0.30% and 0.45% yeast cell wall polysaccharides significantly decreased the amounts of cecum Sal⁃monella and Escherichia coli, but there were no significant differences between pigs receiving 0. 30% and 0.45% yeast cell wall polysaccharides (P>0.05). These findings indicate that yeast cell wall polysaccharides can increase the intestinal volatile fatty acid content and improve intestinal microbial flora of weaned piglets. According to the calculation by the established regression equation, 0.31% to 0.40% yeast cell wall polysac⁃charides is the optimum addition level in the diet of weaned piglet.关键词
