摘　　要：选30 头纯系长白仔猪,按完全随机分组原则分为5 组,每组6 头仔猪,试验Ⅰ、Ⅱ、Ⅲ和Ⅳ组的日粮中分别添加(以稀土含量计) 百万分之五、百万分之十五、百万分之三十、百万分之四十五的复合氨基酸稀土饲料添加剂。经过110 天饲养试验,试验Ⅰ、Ⅱ、Ⅲ和Ⅳ组平均日增重分别比对照组提高16-62 %(P<0-01)、20-73%(P<0-01)、6-82% (P>0-05)和6-09 % (P> 0-05);平均纯收入分别比对照组提高25-26 元、47-40 元、9-62 元和4-04 元。结果表明:在养猪生产中,应用复合氨基酸稀土饲料添加剂能明显地提高增重和经济效益,添加量(稀土计)pure line landrace piglets were dvrided into 5 groups by random sampling,5,15,30 and 45 ppm complex amino acid rare-earth additives were respectively added to the rations of the test group 1,2,3 and 4.After 110 days,compared with the control group,the average daily gain of the piglets of 4 test groups was respectively increased by 16.62%(P<0.01),20.73%(P<0.01),6.82%(P<0.05) and 6.09%(P>0.05).The net income of each fattening pig of the test groups was increased by 25.26,47.40,9.62 and 4.04 yuan respectively more as compared with the control group.The result showed that the application of the rare-earth feed additive can effectively gain in weight of piglets and increase financial benefit in production of pigs.Adding 15 ppm rare-earth additive in the ration of piglet is well suitable for piglets.
