Genetic parameters for the Black Pied Přeštice breed comparison of different multi-trait animal models

Original language description

Genetic parameters were estimated for the Black Pied Přeštice breed using six five-trait animal models. In model variants 1-4, herd and year-season were treated as separate factors which were either fixed or random; model variants 5 and 6 included the combined herd-year-season effect as fixed or random, respectively. The following traits were evaluated: ADGF - average daily gain in the field test (n=22407); LMF - lean meat contents in the field test (n=8864); NBA, NW - number of piglets born alive and wlive and weaned, respectively (n=8979); LWW - litter weight at weaning (n=8783). Model 6 with herd-year-season random was found to show the lowest residual variances for all traits. The estimates of heritabilities and genetic correlations for model 6 were: ADGF 0.26, LMF 0.54, NBA 0.08, NW 0.08, LWW 0.07, ADGF-LMF -0.30, ADGF-NBA -0.10, ADGF-NW -0.13, ADGF-LWW 0.04, LMF-NBA 0.11, LMF-NW 0.10, LMF-LWW -0.09, NBA-NW 0.87, NBA-LWW 0.34, NW-LWW 0.52.
