摘　　要：In order to study the anti-bacterial infection effect of polysaccharide from Agaricus blazei Murrill on chickens, the experimental groups were orally administrated A. blazei polysaccharide at low dose and high dose, respectively, for 14 d continuously, and then, the chickens in various groups were infected with Escherichia coli or Pasteurella pneumotropica , so as to observe the clinical symptoms of chickens and record the change in body weight. Anatomy was performed 14 d later, and the organ indices were determined, so as to study the anti-bacterial infection effect of A. blazei polysaccharide on chickens. The results showed that after bacterial infection, the high-dose A. blazei polysaccharide group was significantly differed from other groups in changes of body weight and organ indices. It indicates that oral administration of high concentration of A. blazei polysaccharide could promote the development of poultry organs, thereby improving the immunity of organisms.In order to study the anti-bacterial infection effect of polysaccharide from Agaricus blazei Murrill on chickens, the experimental groups were orally administrated A. blazei polysaccharide at low dose and high dose, respectively, for 14 d continuously, and then, the chickens in various groups were infected with Escherichia coli or Pasteurella pneumotropica , so as to observe the clinical symptoms of chickens and record the change in body weight.
