Diploma thesis: "Evaluation of growth intensity and meat production of fattening bulls on a specific farm" aims to evaluate the intensity of growth in fattening bulls Agricultural Society as Vítějeves. Evaluation of growth intensity was carried out on 142 bulls of different breeds. Animals were weighed on a quarterly basis according to the weight divided into groups. For each group of animals was measured statistical conclusiveness between weight and additions. Throughout the feed lot bulls were found in the period December 2011 to December 2013 the average weight of 462 kg, average growth was weighing between 918 g.day-1 and average daily gain since birth g.den 998 g.day-1. To evaluate the meat yield of the bulls from the Czech pied cattle breed, the weight was taken on 120th, 210th and 365th day of age, the average daily weight gain since birth was calculated, the average daily weight gain between taking the weight and the weight of body prepared for slaughter was calculated by 1.78 ratio on the animal's weight before the slaughter. Subsequently the effect of the weight, the gain and the slaughter parameters on the slaughter age was assessed and the netto gain and classification to the SEUROP system classes as well. The bulls of Czech Fleckvieh breed average increased within one year of life 774g.day-1, after the one-year increment increased to 967 g.day-1. The average gain from birth to slaughter was 967 g.day-1. Most bulls were slaughtered before the age of 650 days, and their slaughter weight was about 632 kg. For SEUROP bulls were mainly included in class R2. Carcass weight was about 350 kg.
