A large number of studies have shown that chitosan oligosaccharide can improve the growth performance of animals, improve the immunity of the body, regulate the micro-ecological environment of the intestine, etc., and chitosan oligosaccharide also has a relatively low molecular weight, good water solubility, easy moisture absorption, and high biological activity. Advantage. In addition, chitosan oligosaccharide also has the characteristics of pure natural and pollution-free.
01 The effect of chitosan oligosaccharide on the performance of broilers:
Studies have shown that adding an appropriate amount of chitosan oligosaccharide in the diet of broilers has a significant effect on improving the production performance of broilers. Huang R. L. and others concluded through research that different levels of chitosan oligosaccharide (50, 100, 150 mg·kg-1) were added to the diet and compared with the antibiotic group and the blank control group, and found that the feed added with chitosan oligosaccharide Significantly improved body weight gain and feed conversion efficiency of broilers.
02 The effect of chitosan oligosaccharide on the immune performance of broilers
It is understood that poultry has three important immune organs, namely the bursa, thymus and spleen. Deng X. Z. and others concluded through research that the diet supplemented with 100 mg·kg-1 chitosan oligosaccharide has a significant effect on the bursa index, thymus index and spleen index of broiler chickens. Through research, Li Xiaojing et al. concluded that the thymus index and spleen index of broilers added with 100 mg·kg-1 chitosan oligosaccharide were higher than those of other treatment groups, indicating that chitosan oligosaccharide can regulate non-specific immunity.
03 The effect of chitosan oligosaccharide on the growth performance of aquatic animals
Many studies have shown that chitosan oligosaccharide plays a significant role in promoting the growth performance of aquatic animals. Su Peng added different doses of chitosan oligosaccharide in the diet of redfin pufferfish and reared for 56 days. The results showed that with the increasing amount of chitosan oligosaccharide, the growth performance of redfin pufferfish gradually increased, and its weight gain rate, specific growth rate and At the same time, adding chitosan oligosaccharide in the feed can improve the non-specific immunity of fish and optimize the intestinal flora of pufferfish.
04 The effect of chitosan oligosaccharides on the intestinal flora of aquatic animals
The intestinal flora can secrete enzymes that promote the digestion and absorption of fish, so the intestinal flora plays an important role in the digestion, absorption and nutritional immunity of fish. Chitooligosaccharide was added to the feed of juvenile tilapia of Gift. The more the added amount, the more the number of intestinal lactobacilli, while the number of Escherichia coli gradually decreased. Chitooligosaccharide can not only promote the growth of beneficial bacteria in the intestine, but also inhibit the number of harmful bacteria, thereby improving the intestinal environment.
05 The effect of chitosan oligosaccharide on pig performance
Numerous studies have shown that the addition of chitosan oligosaccharide in the diet can improve the performance of sows. Huang Ye and other studies have shown that adding a certain amount of chitosan oligosaccharide can increase the total litter size, live litter size and litter weight of sows.
06 The effect of chitosan oligosaccharide on pork quality
The experimental results of Su Weifa et al. [26] showed that adding chitosan oligosaccharide in the diet can significantly improve the meat color of growing and fattening pigs and improve the antioxidant capacity of the body. Lipid oxidation is an important factor affecting meat quality and affects taste, aroma, color, texture, and nutritional value, among others.
It is concluded that chitosan oligosaccharide can improve animal production performance, slaughter performance, immune performance, etc., and can significantly improve meat quality and regulate the balance of intestinal microorganisms. Nowadays, with the deepening of research, as a functional oligosaccharide, chitosan oligosaccharide has a broader application prospect.
