【Abstract】 Meat Chicken aged from one day were divided randomly into one control group and four experiment groups. The experiment groups received the same basal diet supplemented with different pose of microbial feed additives(MFA).The results showed that MFA can alternate antibiotic feed supplement. The suitable supplement pattern of MFA is supplement in water. The suitable supplement of "BaiDe" MFA in water is 150 mg/kg of Chicken aged from 0～3 weeks and 100 mg/kg of Chicken aged from 4～6 weeks and 50 mg/kg of Chicken aged from 7～10 weeks respectively. The suitable supplement of "BaiDe" MFA in ration is 600 mg/kg of Chicken aged from 0～3 weeks and 400 mg/kg of Chicken aged from 4～6 weeks and 200 mg/kg of Chicken aged from 7～10 weeks respectively. Carcass qualities of Chicken can be improved greatly and medical remain of Chicken can be eliminated by MFA.更多还原
