[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.展开更多
