    The aim of the study was to compare purebred and crossbred Charolaise cattle in respect to their compliance with the breeding goals and standards adopted by the Polish Association of Breeders and Producers of Beef Cattle. The study was based on data for the years 2002–2015 from the PABPBC and for the years 1996–2001 from the National Center of Animal Breeding (NCAB). The properties that were evaluated were the average weight of cows [kg], average body weight of calves after birth [kg], average daily weight gain of calves from birth to 210 days [g], average body weight of calves at 210 days [kg] and average milk yield of cows [kg]. Gradual decline in the share of the national Charolaise beef cattle population was observed as well as sSignificant decrease in the number of crossbreds with Charolaise breed. The aerage weight of cows in 2005–2006 amounting to 559.4 and 570.2 kg (for purebred) and 556.6 and 561.1 (for crossbred) meet the breeding standards for of cows entered in the initial part of the herd book, which define the minimum weight of Charolaise cows after first calving as 550 kg. The average daily weight gain of calves increased considerably in the last years of analysis. The daily body gain of purebred calves was usually higher in purebred population. The daily gains of heifers and bulls were high and usually exceeded 1000 g. For both populations growing trend of daily body gain could be observed. According to breeding standards, body weight at weaning for both heifer and bull calves were at a medium level. The average weight of bull calves was approx. 20 kg higher than the average weight of heifer calves of the same age in both purebred and crossbred populations.
