Abstract
The aim of the study was to assess the utility of selected results of Simmental breed with respect to their compliance with the goal of racial breeding and standards adopted by the Polish Association of Breeders and Producers of Beef Cattle (PABPBC). The subject of the analysis were recording results of the Simmental beef cattle breed. The study was based on data for the years 2002–2014 of PABPBC and the National Center of Animal Breeding (NCAB) for 2000–2001. Evaluated properties are: average weight of cows [kg], the average body weight of calves after birth [kg], the terms of cows and heifers calving aptitude, the distribution of the population according to the order of calving cows. The average weight of cows in 2005–2006 amounting to 568.5 and 522.5 kg meet the breeding standards for of cows entered in the initial part of the herd book. which define the minimum weight of Simmental cows after first calving as 470 kg. The average weight at birth of heifers after 2009 began be lower than 33 kg. In purebred bulls decrease in the average birth weight was noticed.The average daily gains of heifers (550–560 g), guarantee obtaining at 15 months of age body weight allowing the commencement of breeding.
