Effects of Chitoligosaccharide on Immune Function and Intestinal Micro

The key laboratory of pig nutrition and feed in Fujian province found that adding chitosan oligosaccharide to the diet of perinatal sows can improve the intestinal health of sows, increase the number of live piglets to a certain extent, and significantly enhance the immune function of sows and newborn piglets. Chitosan oligosaccharide is a natural alkaline polymer of glucosamine, which has many physiological functions such as immunomodulation, hypolipidemia, anticancer and so on. Chitosan oligosaccharide has been proved to improve the production performance of weaned piglets, which is related to its enhanced immunity, regulation of intestinal flora and improvement of intestinal morphological function.


40 healthy pregnant sows were randomly divided into two groups, the control group fed the basic diet, the experimental group fed the experimental diet with 30 mg/kg of chitosan oligosaccharide. The experimental period was from the 90th day of pregnancy to the 7th day of postpartum (perinatal period).3%; can significantly increase the content of immunoglobulin and interleukin in sows and piglets, enhance immune function; significantly reduce the number of salmonella in sows feces, reduce the number of Escherichia coli in feces, improve the intestinal flora of sows.
