摘要
以32头“杜长大”三元杂交仔猪作为试验动物,研究三阶段和四阶段肥育法对于猪生产性能和胴体组成的影响。结果表明,与三阶段肥育法相比,四阶段肥育法有利于提高日增重和饲料转化率,节约饲料成本,但差异不显著(P>0.05),对胴体组成也没有显著影响(P>0.05)。
piglets(Duroc×Landrace×Yorkshire)were used to study on the effects of three phases and four phases feeding on performance and carcass composition in pigs.The results showed that four phase feeding improve daily gain and feed conversion efficiency(P>0.05),feed cost was decreased(P>0.05).Compared with three phases feeding,carcass composition had no significance difference(P>0.05).
