| 摘 要： | 分析12头海门山羊公羊 418个后代在1996－1998年共4095个生长记录，发现海门山羊生长符合Gompertz模型，生长的最大体重，拐点体重和拐点月龄分别为50．0kg,18．4kg和5．2月，其遗传力分别为0．196，0．196和0．445，初生至断奶日增重平均为108．6g.d^-1，其遗传力为0．415，断奶至8月龄平均日增重为118．0g.d^-1，遗传力为0．338，1－8月龄体重对生长模型参数影响较大。

| Abstract: | Gompertz model was used to fit Haimen goat growth curve.The maximum body weight,growth spinodal weight and spinodal age were 50.0 kg,18.4 kg and 5.2 months,respectively.Corresponding heritabilities were 0.196，0.196 and 0.455 respectively.The growth rate from birth to weaning wa s 108 .6 g*d－1 and its heritability was 0.415.The growth rate from weaning t o 8 month old and its he ritability were 118.0 g*d－1 and 0.338 respectively.The results indica te that 65% of growth variation occurs during months 1 to 8 in the Haimen goat. |
