Estimates of reproduction in cows of Limousine breed and its 50 and 75 percent crossbreds carried out by Polish Association of Beef Cattle Breeders and Producers in the years 1997-2004 was the study material. The study was aimed at estimating the effect of mother's genotype, sequence of calving, housing and sex of the calf on the easiness of calving and the effect of these factors on further results of calves breeding. A highly significant impact of mother's genotype, housing and calf's sex on the easiness of calving in cows of this breed and a significant effect of calving sequence on the considered feature were found. All considered features significantly affected calves' mass at birth. Calving sequence and calf's sex showed a highly significant influence on calves' mass on 365th day but not on calves' mass on 120th day
