摘要
The intestinal immune system is affected by various factors during its development,such as maternal antibodies,host genes,intestinal microbial composition and activity,and various stresses(such as weaning stress).Intestinal microbes may have an important impact on the development of the host immune system.Appropriate interventions such as probiotics may have a positive effect on intestinal immunity by regulating the composition and activity of intestinal microbes.Moreover,probiotics participate in the regulation of host health in many ways;for instance,by improving digestion and the absorption of nutrients,immune response,increasing the content of intestinal-beneficial microorgan-isms,and inhibiting intestinal-pathogenic bacteria,and they participate in regulating intestinal diseases in various ways.Probiotics are widely used as additives in livestock and the poultry industry and bring health benefits to hosts by improving intestinal microbes and growth performance,which provides more choices for promoting strong and efficient productivity.
