Estimation of genetic parameters for litter traits in Czech pig populations using a multitrait animal model
Univariate and multivariate analyses were performed for litter size born, born alive and at 21 days for the breeds Large White, Landrace and Přeštické Black Spotted. Heritability estimates were about 0.10 for all analyses, traits and breeds. High gen...
