Abstract
[Objective] The aim was to increase the performance of sheep.[Method]According to the lactation curve of ewes and the growth-development law of lambs, the milk replacer at standard nutrition level (tested group 1) and 15% lower than standard nutrition level (tested group 2) for 30 days old lambs were prepared for early weaning test, with normal weaning (90 days old) as CK, the daily weight gain and feed conversion rate of lamps and estrus situation of ewes in different tested groups were compared. [Result] The daily weight gain and feed conversion rate of lamps in tested group 1 and group 2 were all higher than those of lamps in CK group, the daily weight gain of 30-90 days old lambs in tested group 1 and group 2 were 164.6, 159.4 g resp., being very significantly and significantly higher than that of lambs in CK group (daily weight gain of 118.7 g) resp.. The estrus of ewes in tested group 1 and group 2 was earlier, being 51, 54 d resp., and that of ewes in CK group was 66 d.[Conclusion]Early weaning of lambs could made the estrus of ewes advanced 12-15 d.关键词
