Breeding value for type traits in beef cattle in the Czech Republic
|Kateg. publikace||Vědecké publikace impaktované|
A model for estimation of breeding value for a description of the type of young animals of beef cattle was constructed. If a majority of evaluated animals is younger than 11 months, it is possible to use a model with linear regression on age at evaluation; otherwise it is suitable to apply a model with quadratic regression on age at evaluation. Deviations from normal distribution in the scoring of height at sacrum and live weight document that different method that would correspond with evaluation of the other traits should be used. High genetic correlations between some traits indicate the possibility of reducing the number of evaluated traits.
