Estimation of additive and dominance genetic variance of reproduction traits in Austrian Simmental cattle with Method R
Abstract
Selection for functional traits is getting more important under actual socio-economical circumstances. Fertility, calving ease and stillbirth are among those traits which reduce production costs and improve animal health and welfare. Furthermore, large dominance effects (in comparison with additive effects) are expected for these traits. These could be used to implement oriented mating programs. To achieve efficient selection, precise estimates for heritabilities, dominance variance and genetic correlations are required. Method R is a recent method for variance components estimation which can handle the required large data sets. Those estimates will then be used to compare the efficiency of different selection methods for these traits.
