摘要

为了评价生长性状的遗传进展,使用了1986 - 2016年39408只莫加尼羊育种站的家系信息。研究的特征包括出生体重、断奶体重、6个月体重、9个月体重和一岁体重。利用袋熊软件,通过限制似然法和6种动物模型对各性状的方差成分和遗传参数进行估计。初生体重、断奶体重、6月龄体重、9月龄体重和1周岁体重的直接遗传力分别为(0.07、0.09、0.15、0.13和0.20)。利用单变量最佳动物模型估计各性状遗传趋势计算的育种值。通过对表型平均值、育种值平均值和育种值与表型值的差值除以出生年份的回归,估计性状的表型、遗传和环境趋势。初生体重、断奶体重、6月龄体重、9月龄体重和1龄体重的遗传趋势计算值分别为0.008、0.012、0.054、0.74和0.145 kg/年,除初生体重外,其余均极显著(p<0.01)。初生体重、断奶体重、6月龄体重、9月龄体重和1龄体重的遗传增重分别为0.213、1.071、1.171、1.164和1.324 kg。在评价年份,观察到性状的遗传趋势有许多波动。换句话说,在研究的年代里,似乎没有一个全面的计划来遗传育种和改善莫加尼羊的体重特征。

Genetic progress evaluation of growth traits in Moghani sheep
For evaluation of growth traits' genetic progress, pedigree information of 39408 Moghani sheep, between 1986 to 2016, at the breeding station of Moghani sheep was used. Studied traits included birth weight, weaning weight, six months weight, nine months weight, and one yearling weight. Variance components and genetic parameters of traits were estimated by restricted likelihood and six animal models using Wombat software. Direct heritability of birth weight, weaning weight, six months weight, nine months weight, and one yearling weight was (0.07, 0.09, 0.15, 0.13, and 0.20 respectively). Breeding values for the calculation of genetic trends for each trait were estimated by using the univariate best animal model. Phenotypic, genetic, and environmental trends of traits were estimated via regression of phenotypic average, breeding value average, and difference of breeding value from phenotypic value divided by birth year. The calculated genetic trends of birth weight, weaning weight, six months weight, nine months weight, and yearling weight were 0.008, 0.012, 0.054, 0.74, and 0.145 kg/year respectively, except for birth weight, the others were significant (p<0.01). The genetic gain of traits including birth weight, weaning weight, six months weight, nine months weight, and one yearling weight was estimated (0.213, 1.071, 1.171, 1.164, and 1.324 kg respectively). At evaluated years, many fluctuations were observed in the genetic trend of traits. In other words, it seems at the studied years, there wasn't a comprehensive plan for genetic breeding and improvement of body weight traits in Moghani sheep.
