In this experiment, 1000 healthy Phoenix chicken with similar health and weight were used as the research object. The effects of feed additives on the growth, morbidity and mortality of the Chinese herbal feed additives were analyzed. The results showed that the average weight and daily weight gain of the chickens in the test group (Chinese herbal medicine group) were significantly higher than those of the control group (P0.05) after 14 days of age, and the weight ratio test group was significantly lower than the control group (P0.05), and the mortality test group was 9.2 percentage points lower than that of the control group. Therefore, the Chinese herbal prescription used in this experiment can promote the growth and development of broilers, prevent and control diseases, resist pathogenic microbes, and reduce the incidence and mortality of chickens.
