摘　　要：[目的]研究代乳料对羔羊生产性能及血液生化指标的影响，探讨羔羊早期断奶的可行性。[方法]将37只10～15日龄的白头萨福克（♂）×小尾寒羊（♀）F1羔羊随机分为A、B、C、D 4个组进行试验。其中，A、B、C3组羔羊分别饲喂3种不同的代乳料；D组羔羊为对照组，不断奶，随母羊哺乳。分别测定各组的生产性能指标及血液生化指标。[结果]生产性能指标：10～15日龄时，B、C组日增重显著低于D组（P〈0．05），而A组与D组间差异不显著；16～25、26～35日龄各组羔羊日增重均无显著差异；46～55日龄时，试验组羔羊日增重显著高于对照组（P〈0．05）。血液生化指标：B组和C组的血浆尿素氮（PUN）显著高于A组（P〈0．05），B组和C组间差异不显著；各组中血浆白蛋白（ALB）含量比较接近，无显著差异；B组总蛋白（TP）含量有高于A组和C组的趋势，但差异不显著；A、B、C3组间总氨基酸浓度差异不显著。【结论】用代乳料饲喂羔羊并实现羔羊的早期断奶是可行的。[ Objective ] In this study, the performance and blood biochemical indices in lamps fed on milk replacer were researched, the feasibility of early weaned in lamps was discussed. [Method] 37 of 10 days lambs of Suffolk（ ♂ ） x XiaoWeiHanYang（♀ ） were randomly divided into group A,B,C,D for this experiment. Group A, B, C were fed by 3 milk-replacers containing milk for different protein somw respectively, and ten lambs in each group; group D （seven lambs） were fed by ewes as the control. The performance and blood biochemical indices of the lamps were determined. [Result] The results showed that the average daily gains of 10 - 15 days of age was not significantly different between group A and D（P 〉 0.05）, the control were higher significantly than the group B, C （ P 〈 0.05）.The average daily gains of 16 - 25, 26 - 35 days of age were not significantly different in group A, B, C, D. The daily weight gains of Group A, B, C in 45 - 55 days of age were higher significantly than the control （ P 〈 0.05）. Plasma urea nitrogen （PUN） of group B and C were higher than group A significantly （ P 〈 0.05 ） ; Total protein （TP）, Plasma albumin （ALB） and Plasma total amino acid were no significant difference among the other 3 groups （ P 〉0.05）.[Conclusion] So, the milk-replacers were available for early-weaned lamb.
