摘要
利用开阳县当地盛产的玉米、米糠作为能量饲料,100头"大长杜"三元杂交仔猪,分2组进行饲养对比试验,试验组使用已获得国家绿色认证的云南省某公司生产的浓缩饲料,对照组使用市面常见的某厂家的浓缩饲料(无绿色认证),分别按配方要求配制饲料,饲养125 d后,对测定各组日增重、料肉比、经济效益等指标进行分析,结果表明:试验组平均日增重比对照组提高5.23%,差异显著(P<0.05);料肉比比对照组低6.12%;饲养成本也有所降低。
A feeding experiment on 100 ternary hybrid pigs, Large Yorkshire× Landrace ×Duroc, was carried out with the local energy feed （corn, rice bran） at Kaiyang. The experimental group was fed with concentrated feed which was produced by a company of Yunnan province with national green certificate, and that for control group was common concentrated feed without the certificate. The feeds were prepared with formula and to feed for 125 days. The results showed that the average daily gain of the experimental group increased by 5.23% comparing to the control group. It was significantly different （P〈0.05）. The feed conversion ratio increased by 6.12% and the feeding cost had a slight reduce.
