Czech mottled cattle is the original breed of cattle in the Czech Republic. It is part of a worldwide population of mottled breeds of the same phylogenetic origin, widespread, for all its continents, for its excellent properties and widespread use. It currently accounts for about one half of the total cattle population in the Czech Republic. The aim of the work was to monitor the growth of fattened bulls, focusing on the last half year of fattening and trying to determine the inflection point of fattening this breed under given breeding conditions. Furthermore, the monitored bulls were compared on the basis of genetic potential, ie the representation of the blood of the Czech spotted breed and according to the father. Fattening bulls are only from their own breeding as weaners from milked herds. The bulls are fattened up to the age of 24 months and are divided into groups of about 24pcs, depending on the weight. The feed is given to them twice a day, at regular intervals, with a mixing feed wagon with weight. The feed consists of corn silage, clover-grass silage and a core mixture, which the company produces itself. The results obtained did not show a statistically significant difference in the pre-slaughter live weight by father line, by month of birth of the individuals studied or by age at slaughter. Only by comparing the live weight before slaughter by SEUROP, there was a statistically significant difference.
