one-day chicklings were chosen to study the effect of different supplemental level of Yeast Culture insteading antibiotic on chickling's production performance. The results were following: there was no significant difference on production performance until the third experiment week; compared with the control group, the 0.3%YC group and the flavomycin group improved the weight by 5.72%? 6.24% respectively(P0.05), improved the average weight gain by 6.37% and 6.92%(P0.05); 0.1%YC? 0.3%YC group improved the availability of dietary P by 20.22%? 22.11% respectively(P0.05), compared with the control group. This study indicated that 0.3%YC had the best effect, it not only improved the body weight, but also improved the availability of dietary P.
