微生态制剂在肉鸡饲料中应用效果的研究

A Study on the effects of Microbial Feed Additives On Feeding Efficiency of Meat Chicken

试验选用 1日龄商品代黄羽肉鸡混合苗 5 0 0只 ,随机分成五组 ,设 1个对照组及 4个试验组。试验组分别在对照组基础上添加不同剂量微生态制剂 ,以探讨其效果。结果显示 :“保得”微生态制剂能够取代肉鸡饲粮中的抗生素、抗菌药物类生长促进剂 ;微生态制剂适宜添加方式为饮水中添加 ;饮水中“保得”微生态制剂适宜添加量为小鸡 15 0mg/kg、中鸡10 0mg/kg、大鸡 5 0mg/kg ;饲料中“保得”微生态制剂适宜添加量为小鸡 6 0 0mg/kg、中鸡 40 0mg/kg、大鸡 2 0 0mg/kg ;

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.
