Abstract
The experiment studied the effect of 2 kinds of Chinese herb extracts on chickens' performance. 240 one day old healthy chickens were chosen in the test and divided into 3 groups at random, i.e. blank control group, Test Group I and Test Group II with 80 chickens in each group. The Chinese herb extracts I and II were added into the basal diet as per 0.6 % of Group I and II resp. with 21 d of experiment period. The results showed that the daily gain of chicken in Group I and II was higher 4.71 % and 2.43 % than that of control group; the feed-weight ratio of Group I and II chickens was lower 15.35 %(P0.05)and 19.29 %(P0.05)than that of control group; the survival rate of Group I and II chickens was higher 7.5 % (P0.05)and 6.25 % than that of control group; The economic benefit of Group I and II chickens was higher 26.37 %(P0.05)and 29.67 %(P0.05)than that of control group. It indicated that the Chinese herb extracts I and II being added into the chickens' basal diet could increase the chickens' daily gain, feed conversion rate and survival rate, and was able to promote chicken growth and boost economic benefit significantly.
