摘　　要：[ Objective] The paper presents the effects of Chinese herbal extract on the performance of local chickens for its application in animal production. [Method] The herbal extract Ⅰ and Ⅱ were added to the basal diet of 10 day-old chickens at the ratio of 0.6%, respectively. Then the chickens was fasted and respectively weighed at 0, 17, 24 and 31 days old. And the feed consumption and mortality of each group were recorded to determine average weight, average daily gain, and feed conversion ratio. Economic benefit was also analyzed. [ Result] There was no significant difference in average daily gain between the test groups and the control group as well as between the two test groups （P〉0.05） ; there was signifi- cant difference in feed conversion ratio between the test groups and the control group （ P 〈0.05）, but no significant difference between the two test groups （ P 〉 0.05） ; the survival rate and the economic benefits of the test groups were significantly higher than that of control （ P 〈 0.05）. [ Conclusion ] Chinese herbal extract Ⅰ and Ⅱ should improve chicken average daily gain, feed conversion ratio and survival rate, promote growth, and signifi- cantly improve economic benefit.[ Objective] The paper presents the effects of Chinese herbal extract on the performance of local chickens for its application in animal production.
