Theme of this work is breeding of cattle meat breed Hereford breed and their crossbreds with Charolais and Czech spotted cattle. We monitored the influence of sex, breed of father and mother, parity and month of calving on the average weight of calves at 120, 210 and 365 days of animal age. Growth of calves in individual cross combinations were evaluated too. The study was performed on the selected herd of 215 pieces of cattle: 85 of Hereford breed, 68 of Charolais breed and 62 of Czech spotted cattle breed. The herd is bred on the private farm with a total area 90ha of pastures located in the South Bohemian village Lhota near Mladosovice. We used information and performance of the herd of cattle between the years: 2017 and 2018. This diploma thesis confirms that higher average weights can be attain as crossbreeding of meat breeds and also by crossbreeds with dual purpose cattle breeds. Calves born in the late months of the year come up to higher average weights too. From the statistical analysis it is possible to prove the influence of the parent combination on the average weights of calves and their weight gains. The lowest weight gains were observed in calves of crossbred combination of Charolais vs. Czech spotted cattle (0.83 kg per day) and the highest values were detected in calves of Charolais vs. Hereford breeds (1 kg per day).
