日粮添加可直接饲喂微生物对生长肥育猪生产性能的影响

Effect of Dietary Direct-Fed Microbials Addition on the Performance of fattening pigs

试验选用 12 0头 80日龄 ,体重约 2 5kg的三元杂交 (杜×长×大 )商品代瘦肉型生长肥育猪 ,随机分为 2组 ,分别设为对照组和试验组 ,每组两个重复 ,每个重复 30头猪 ,对照组饲喂基础日粮 ,试验组饲料在对照组日粮基础上添加可直接饲喂微生物。经过 31d的饲养试验 ,结果表明 :①试验组猪只的日增重比对照组提高 6 .0 7% (P <0 .0 5 ) ,料肉比比对照组提高 3.2 8% (P >0 .0 5 ) ;②经济效益 ,试验组猪只提高了 8.11% ;③试验组猪只的腹泻率较对照组降低 5 .6 7%。

three-way cross-bred [Duroc×(Landrace×Yorshinee)]lean meat fattening pigs were used to evaluate the effects of direct-Fed Microbials.Initial average weight of fattening pigs is 25 kg(P>0.01).Initial age is 80 days.The fattening pigs were randomly divided into a trial group and a control in duplicates(30 fattening pigs for each groups),fed with or without Direct-Fed Microbials(DFM) respectively.After 31 days fed,the result showed that the average daily gain of trial group increased by 6.07%(P<0.05)and feed to gain ratio increased by 3.28%(P>0.05).Result also demonstrated that the group feed DFM increased income of production by 8.11% and had a lower incidence of diarrhea.
