Abstract: [Objective] Early weaning during the lamb suckling stage combined with supplementation of nutritionally adequate and easily digestible milk replacer powder is an important technical approach to improving lamb growth performance. [Method] In this study,23 healthy male lambs aged 20 days were randomly divided into three groups： the mother's milk group（naturally suckled by ewes）,the commercial milk replacer powder group（fed with commercial milk replacer powder）,and the self-formulated milk replacer powder group（fed with self-formulated milk replacer powder）. [Result] The weaning weights at 60 days of age in both the self-formulated milk replacer powder group and the commercial milk replacer powder group were significantly higher than that in the mother's milk group（P<0.05）. The average daily weight gains during the periods of 50~60 days of age and 20~60 days of age were also significantly higher than those in the mother's milk group（P<0.05）.The intake of milk replacer powder in the self-formulated milk replacer powder group was significantly higher than that in the commercial milk replacer powder group at all ages（P<0.05）.The diarrhea rate of lambs in the self-formulated milk replacer powder group was 9.13% lower than that in the commercial milk replacer powder group and 5.13% higher than that in the mother's milk group. There were no significant differences in body length and chest circumference among the groups at any stage（P>0.05）;however,the body height and cannon circumference of lambs in the self-formulated milk replacer powder group at 40 days of age were significantly higher than those in the commercial milk replacer powder group and the mother's milk group（P<0.05）. [Conclusion] Economic benefit analysis showed that the self-formulated milk replacer powder group had the highest economic returns. Supplementation with self-formulated milk replacer powder can significantly improve lamb growth performance,reduce diarrhea rates,meet the nutritional requirements for lamb growth and development,and provide good economic benefits,offering an effective reference for optimizing early weaning techniques in lambs.
