The aim of the study was to investigate the effect of origin, age at first calving and calving season on body weight and conformation traits in limousine cows. A highly significant dependence was found between the origin of cows and their general appearance (constitution, type), and a significant dependence between the country where the animals had been purchased and their body weight. The most advantageous results were recorded for cows coming from the Czech Republic. Calving season was found to have an effect on body weight, height at the sacrum and the total score in conformation judging in a 100-point scale. More valuable values for the analysed traits were recorded for the animals which calved in the spring-summer season, which was most probably the result of more effective pasture feeding in that period. It was found that the age at first calving has a highly significant effect on body weight and scores of general appearance (constitution, type), limb locomotion score, as well as a significant effect on the forequarters (depth, width), barrel (back, loins, abdomen) and rump (the sacrum, pelvis, shape). However, the results collected within this study suggest that the most significant factor determining service date of limousine heifers is their body weight, and not their age.
