Abstract: The growth performance and immunity of Xingyi bantam fed with daily ration plus 5%A.bhotanensis powder were studied by measuring body weight,shinbone length,immune organ indexes and antibody titer of chicken against Newcastle disease to provide the theoretical basis for application of A.bhotanensis in cultivation of Xingyi bantam.The results showed that A.bhotanensis powder has the significant positive effects on body weight of Xingyi bantam with 8~20 weeks age and growth of shinbone length of Xingyi bantam with 4~20 weeks age,improves immune response,enhances immune efficacy of Newcastle disease vaccine and promotes growth of thymus,bursa fabricius and spleen.A.bhotanensis with the similar function to Astragalus membranaceus in cultivation of Xingyi bantam should be used as a Chinese herbal medicine feed additive for popularization and application.
