In this study, silkie chickens were selected as the experimental subjects and randomly divided into two groups, one as the control group, and the other was added with Chinese herbal feed additives. The experimental period was 8 weeks. By observing and measuring the indicators of chicken production performance (body weight, feed conversion ratio, egg production rate) and immune organ index (spleen index, thymus index, plasma cell index), the impact of Chinese herbal feed additives on silkie chickens was analyzed.【Keywords】Chinese herbal feed additives; silkie chicken; production performance; immune organ index
