摘　　要：[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 source respectively, and ten Iambs 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 〉 O. 05 ）, the control were higher significandy 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.早期断奶可使羔羊尽早适应固体饲料，从而加快其消化道尤其是瘤胃的发育，进一步完善消化器官和消化腺的功能，为其将来采食大量饲料，提高生产性能打下基础。此外，实行早期断奶，不仅能大大降低母羊的饲养成本，而且有助于母羊提前进行生理和体况恢复，为在母羊群中实行高效高频繁殖，从而为工厂化养羊奠定基础。该试验对羔羊代乳料的饲喂效果进行了研究。
