The results for purebred Charolaise and Limousin population as well as their crossbreds with Polish Black-and-White cows were analysed. The permanent increase of Limousin genes share in purebred and crossbred and stable share of Charolaise genes in purebred female population were observed. Body weight of purebreds and crossbreds with Charolaise breed are out of standards of breeding goal, when with Limousine breed slightly differ from it. There were no differences in body weight at birth between purebred and crossbred Limousin calves. Purebred Charolaise calves were much heavier than the crossbreds. Average daily body weight gain of purebred heifer calves were higher than those stated in the breeding standard, whereas for crossbred heifers were much lower. Purebred calves had higher body weight at weaning than the crossbreds. The differences were heigher for Charolaise (21 kg bulls and 28 kg heifers) than for Limousin breed (5 and 4 kg)
