The routine methods were used for assessment ofgrowth rate, survival rate, feed conversion rate (FCR), productivity and disease resistance of theexperimental chickens. The studied result showed that the survival rate of chickens at 12 weeksold in two experimental groups with Ji Kang pharmaceutical products adding into feed reached89.26% - 94.81%
and the average body weight reached 2340g and 2580g, respectively. TheFCR of chickens in the experimental groups was lower in comparison with chickens in the controlgroup (2.52 vs. 2.68). The meat rate of the experimental chickens reached 71.73% - 72.33%, thedisease infection rate of the experimental chickens was also low (3.33% - 5.55%).
