[Using VCE4.0 package to estimate genetic parameters on growth traits in Landrace].
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.
