摘  要：
为了估算如皋黄鸡280日龄体重遗传力,分析遗传模型的适用性,本研究收集2009-2013年如皋黄鸡生产记录,整理后得到8116条体重记录,对不同日龄体重进行了标准化。应用WOMBAT软件分析表型方差组分,计算遗传力时考虑了年、批次以及母本日龄对表型方差的影响,以AIC值、BIC值选择最优模型。结果表明:如皋黄鸡280日龄体重性状遗传模型应考虑批次效应和母本日龄效应;应用个体动物模型计算的如皋黄鸡280日龄遗传力为0.52±0.03,应用sire模型计算的如皋黄鸡280日龄体重遗传力为0.56±0.02。遗传分析结果显示,280日龄体重属于中等遗传力性状。应用BLUP方法预测育种值可以进一步提高如皋黄鸡280日龄体重整齐度。

摘  要：
To estimate the heritability for body weight at 280 day-old in Rugao Yellow chicken,to evaluate the influence of different models on genetic effects.The data were collected from Rugao Yellow chicken population from 2009 to 2013.A total of 8116 body weight records from laying hen were evaluated.The records at different day-olds were standardized to280 day-old body weights.Variance components were obtained by WOMBAT software.The influences from year,batches and dam age were considered during evaluation of heritability.Models were compared using AIC and BIC values.The results suggested that the influences from batches and dam ages should be included in the fix effects.The heritability of 280day-old body weight was 0.52 ±0.03 with animal model, and 0.56 ±0.02 with sire model.The heritability for the body weight at 40 weeks were moderate.In the future,Expected Breeding Value(EBV) predict with BLUP able to improve the uniform of the body weight.
