摘要
为探讨适合四川省实际的种猪测定饲料配方及适宜的饲喂方式,本试验采用了两因子重复设计,即三种不同营养浓度的饲料、自由采食和定量给食两种饲喂方式,对48头杜长仔猪进行试验,测定猪在30～100千克体重阶段的日增重和耗料指数,并观察不同钙、磷水平对猪四肢的影响.试验结果表明三种不同营养浓度的饲料和饲喂方式对猪日增重和耗料指数均无显著影响,但营养浓度略低的饲料成本较低.为便于管理,采食方式建议采用定量给食的饲喂方式,对试猪四肢观察结果表明,钙、磷水平最高的一种饲料,可在一定程度上缓解因生长过快造成的四肢病症.
In order to probe into feed formula and its feeding methods for performance testing of breeding swine fitted to the practice in Sichuan an experiment with 2 factors repeated design was carried out． Three nutritional levels and two feeding methods were included． Average daily ADG and feed conversion ratio FCR were tested with 48 crossbreed piglets Duroc×Landrace from 30～100kg live－weight． Besides the effect of Ca and P levels in the rations on the legs was evaluated． Results show that there were no significant differences of ADG and FCR affected by all factors studied． But lower nutritional level cost less． Ad lib feeding was suggested in performance testing． Higher level of Ca and P in the ration could alleviate leg problems of pig to some extent due to fast growth．
