Research progress of probiotics used in poultry feed

The supplement of probiotics in the diet contributes to the gut health and nutrient use,which benefits animals in nutrient absorption and immune modulation.Probiotics increases the villus height and structure of the intestinal mucosa,which can improve the nutrient digestion and absorption,enhance the regulation function of tight junctions in epithelium to defence against pathogenic bacteria and maintain cellular homeostasis.Heat stress is the major environmental challenge in the poultry industry.The use of probiotics can overcome the heat stress challenge.
