Ekonomické zhodnocení intenzivního výkrmu býků masných plemen skotu
Kosová, Michaela
The diploma thesis deals with the fattening of slaughter bulls of the Aberdeen Angus, Charolais and Limousin breeds from the weight category to slaughter weight. The main goal of this work was to economically evaluate the effectiveness of intensive fattening of beef bulls. A total of 366 animals were monitored in two feedlots. In the practical part, the animals were weighed in different stages of fattening, at the age of 8 and 14 months, and on the basis of these data, an analysis of the influence of the breed was carried out and subsequently the economy of fattening was evaluated. Growth was assessed by average gains for individual breeds and farms. The results show that the breed has a significant effect on the intensity of growth. The results were statistically significantly highest in the Aberdeen Angus breed in the pre-weaning period (1.12 kg/day), but after moving to a barn with intensive fattening, the highest growth intensity was achieved in the Charolais breed (1.61 kg/day). Weight increased linearly with age in all bulls, the highest differences were observed in the Aberdeen Angus and Limousin breeds. After the 1st and 2nd weigh-ins, representatives of the Aberdeen Angus breed (330.02 kg, respectively 579.57 kg) achieved the highest weights, while representatives of the limousine reached the lowest (302.24 kg, respectively 555.27 kg). The absolute highest average daily gains were achieved by bulls of the Charolais breed, in 160 days of intensive fattening, the absolute gain was 255.3 kg. Despite the lowest age, the bulls had the highest weight at the end of fattening, thanks to the high intensity of growth. The highest calculated profit was achieved on Farm A with the Charolais breed (CZK 8,838.37) and on Farm B with the limousine breed (CZK 2,645.6). The costs per feeding day ranged from 89 to 91 CZK.
