Temperament data of 57 947 Austrian Simmental (Fleckvieh) dual purpose cows were analyzed. General temperament was scored in four categories from very calm to very nervous and scores for milking temperament were based on a 3-point scale from easy to very nervous. The statistical model included the fixed effects herd-year-season, parity and lactation stage as well as the random animal effect. Estimated heritabilities were 0.04 and 0.05 for temperament and milking temperament, respectively. The genetic correlation between the two temperament traits was high (0.85). Genetic correlations with milk production traits, milking speed and body condition score were low. EBV correlations suggest no practically relevant relationship of temperament with production, fitness and type traits. No routine genetic evaluation for temperament is currently being implemented in the Austrian-German Simmental population.
