Genetische parameter der mast- und schlachtleistungsmerkmale von reinzucht- und kreuzungsschweinen unter simultaner parameterschätzung

Genetic parameters of daily gain, lean meat percent and age were estimated for the Hungarian Large White, Hungarian Landrace and their cross. The analysis was based on the national database from field tests (1997-2010) using bivariate animal models. Estimated heritabilities for the analysed traits ranged between 0.21-0.36. Relative importance of random litter effects was low except for age, where the estimates exceeded notably (0.46, 0.49) the estimates of the other traits (0.17-0.33). The genetic correlations between purebreds and crossbreds were for all traits low to moderate, for daily gain r_g = 0.47 and 0.37, for lean meat percent r_g = 0.46 und 0.28 and for age r_g = 0.26 und 0.25.
