[en] Heritabilities and genetic correlations were estimated in first, second and all parities for dystocia and stillbirth for the Austrian Simmental population. Method ℜ was applied to estimate the (co) variance components with a linear animal model. In total, 1,399,990 calving records were analyzed. There were 363,097 first-and 274,486 second-parity records. The largest pedigree file consisted of 1,842,324 animals. Both traits were recorded categorically, 4 and 2 classes for calving ease and stillbirth, respectively.
