| 摘 要： | 应用PEST和VCE4.0对温氏长白猪的主要生长性状进行了遗传分析。利用温氏水台原种猪场1998～2002年的6344头长白猪生长性能测定记录，运用多性状动物模型REML方法估计主要生长性状的遗传参数。估计遗传力的变化范围为0.207～0.493，性状达30kg体重日龄（AGE30）、达100kg体重日龄（AGE100）、30～100kg平均日增重（ADG）和100kg体重活体背膘厚（FAT）的估计遗传力分别是0.207、0.396、0.304和0.493；FAT/ADG、FAT/AGE100、ADG/AGE100、ADG/AGE30和AGE30/AGE100的各自遗传相关为-0.343、0.180、-0.941、-0.48和0.745；它们的表型相关分别为-0.139、0.138、-0.829、-0.026 和 0.565；AGE30、AGE100、ADG和FAT的窝效应估计结果分别为0.194、0.156、0.157和0.043。

| Abstract: | It is an accurate and quick methods to apply VCE4.0 to estimating genetic parameter. It makes full use of all information, analyzing selection and culling effects. The Genetic parameters for the age to 30kg(AGE30), age to 100kg (AGE100), and average daily gain from 30kg to 100kg (ADG) and backfat thickness at 100kg(probed,FAT) are estimated using VCE4.0 applied to REML with a multivariate individual animal model in Landrace pigs. Estimates of heritabilities for AGE30, AGE100,ADG and FAT are 0.207,0.396,0.304 and 0.493, respectively. Genetic correlations for FAT/ADG, FAT/AGE100, ADG/AGE100, ADG /AGE30 and AGE30/AGE100 are -0.343,0.180,-0.941,-0.48,and 0.745, respectively, its phenotypic correlations are -0.139,0.138,-0.82,-0.026, and 0.565, respectively. The common litter environment effects for AGE30,AGE100, ADG and FAT are 0.194,0.156,0.157 and 0.043, respectively. |
