安来霉素在肉鸡日粮中的应用研究

Studies on the Application of Enramycin in Broiler Diets

应用安来霉素、金霉素、杆菌肽锌三种抗生素药物添加剂，对１２００只ＡＡ肉鸡进行生产性能和经济效益对比，试验分三组。安来霉素组（１０ｍｇ／ｋｇ）、金霉素组（１００ｍｇ／ｋｇ）；杆菌肽锌组（７５ｍｇ／ｋｇ）。每组设４个重复组。采食安来霉素饲养的鸡只，日增重比金霉素高０５６％（Ｐ＞００５）、比杆菌肽锌组高６１７％（Ｐ＜００５）。饲料转化率分别比金霉素组高１４３％（Ｐ＞００５），比杆菌肽锌组高７２％（Ｐ＜００５），屠宰测定表明三组之间差异不显著（Ｐ＞００５）。经济效益分析表明安来霉素组分别比金霉素高组３７５％，比杆菌肽锌高组３１６％。试验结果表明安来霉素可以显著改善肉鸡的生产性能，提高经济效益。

The enramycin, CTC, bacitracin zine were used in the experiment as antibiotics additives in broiler diets to contrast their effects on growth performance of broilers. One thousands and two hundred broilers were radomly assigned into three groups. There were four replicates in each group. The diets of the groups contanied enramycin (10 mg/kg), CTC (100 mg/kg) and bacitracin zine (75 mg/kg). ADG of enramycin group was 0.56% (P>0 05),6 17%(P<0.05) higher than two other groups, F/G was 1.43%(P>0 05),7 2%(P<0 05) higher than the two other groups respectively. Its benefit was better than the two groups,prmoted in degree of 3.75%, 31.6% respectively. This experiment showed that enramycin can improve growth performance and is of benefit for poultry production.
