The aim of this master thesis was to evaluate the effect of the year on the growth ability and the birth process of charolais breed at the selected organic farm. Review is focused on the characteristics of charolais, breeding, performance testing, births, birth weight, growth, calving season, livestock grazing, organic farming and cattle breeding in organic farming. Evaluated results from the growth ability recording scheme on the private organic farm were described in experimental part of this work. Measured values were birth weight, weight in 120 and 210 days. Further the experimental part was focused on the birth process. All presented results were compared with values from the Czech Republic records. It has been found that charolais from the organic private farm has higher average growth ability compares to the Czech Republic. In the years 2011 to 2015 was measured average birth weight of 46.7 kg for bulls and 42.9 kg for heifers. Average weight at 120 days was 196.1 kg for bulls and 180.3 kg for heifers. Average weight at 210 days was 324.7 kg for bulls and 295.1 kg for heifers. The births were almost always evaluated like easy in the monitored farm. During evaluating calving season, results show 63% of the births from January to March. At the end is evaluate the impact of the air temperature and rainfall on the yield on feed, where we can say that for the growth of grassland is not important how many millimeters of annual rainfall is, but the distribution and frequency of rainfall.
