发酵饲料替代抗生素在断奶仔猪日粮中的应用

Fermented Feed to Replace Antibiotic Application in Weaned Piglets Diet

文章旨在研究生物发酵饲料在断奶仔猪饲养的应用效果,从而为抗生素替代品提供一种新尝试。试验将150头断奶仔猪按体重大小随机均分为15栏,设对照组、发酵饲料组、抗生素组3个处理,每个处理5个重复,每个重复10头猪,饲养45 d并观察记录各项指标。结果表明,发酵饲料组猪的平均日增重和粗蛋白表观消化率显著高于对照组(P<0.05),料肉比和腹泻率低于对照组,表明发酵饲料可以提高断奶仔猪的生长性能和消化能力,降低猪的腹泻率和料肉比,增强猪健康状况。

This article was to study the application effect of fermented feed on weaning piglets, thus providing a new attempt to substitute antibiotics. In the experiment, 150 weaned piglets were randomly divided into 15 columns ac- cording to body weight. These weaned piglets were divided into three treatment groups, each treatment group includes five replicates and each replicate had 10 pigs, respectively as the control group, fermentation feed, antibiotics group. The experiment lasted for 45 days. The results showed that the average daily gain of the pigs and the apparent digest- ibility of the crude protein were significantly increased in the fermented feed group compared with the control group （P〈0.05） and the ratio of feed to meat and diarrhea rate was decreased compared with the control group. The results showed that fermented feed could improve the growth performance, digestibility of weaned piglets and reduce the diar- rhea rate of pigs, the ratio of feed to meat and enhance the pig＇s health.
