发酵床养猪饲料中不同抗菌成分饲养育肥猪试验

Trial of Feeding Finishing Pigs on Fermenting Bed with Different Antibiotics in Feed

为探讨饲料中不同抗菌物质对发酵床养猪效果,对育肥猪进行了试验。结果表明,微生态组、抗菌肽组和对照组育肥全期日增重分别为0.670、0.658和0.639 kg,料肉比分别为2.840、2.987和2.962;经济效益分别为3.71、3.18和3.54元;整个育肥阶段,微生态制剂优于对照组,抗菌肽则比对照组略差。检测结果显示,微生态和抗菌肽粪便和垫料中氮磷和铵态氮均较对照组低,微生态制剂优势更明显。

In order to provide a reference for technology of finishing pig with antimicrobial substances in feed on the fermentation bed.The result showed that the daily weight gain were 0.670,0.658 and 0.639 kg;feed conversion were 2.509,2.453 and 2.687;economic benefits were 3.71,3.18 and 3.54 yuan respectly.The microbial group was better than the control,and the antimicrobial peptides was worse than the control group.Test results showed that the nitrogen,phosphorus and ammonium nitrogen were lower in microbial and the antimicrobial peptides than in the control group,and the microbial was the best of all.
