日粮中添加富马酸稀土络合物对黄杂肉用仔鸡增重的影响

Effect of Supplementing Rare-earth Complex Compound with Fumaric in Ration on Liveweight Gain of Yellow Hybrid Broiler

将32日龄黄杂肉用仔鸡240只随机分成4组,对照组饲喂基础日粮,试验组是喂在基础日粮中分别添加500,400,300mgkg的富马酸稀土络合物的日粮。结果表明,添加500mgkg富马酸稀土络合物组的效果最佳,只均增重938g,比对照组鸡(836.5g)提高12.27%,料重比(3.04∶1)比对照组鸡降低13.14个百分点,料重比和经济效益都比对照组好。

240 Yellow hybrid broilers at the age of 32 days were randomly divided into four groups.The broilers of control group were fed the basal ration and one of treatment groups were fed the basal ration with 500,400,300mg/kg rare-earth complex compound with fumari acid respectively.The results showed that the gain effect of broilers in treatment group fed the ration with 500mg/kg rare-earth complex compound with fumaric acid was highest.The average 1iveweight gain per broiler was 938g which increased 12.27% than that of control group (836.5g) and the ratio of feed to gain (3.04∶1) decreased 13.14 percent point than that of control group.The ratio of feed to gain and the economic benefit were more than those of control group.
