The bulls carcass quality on seurop system

Popis výsledku v původním jazyce

The aim of the study was to evaluate the effects of the slaughter age at bulls, the carcass weight and the level of the daily net gain on the carcass classification according to the SEUROP system. The carcass classification for the statistical analysis was carried out according to the following system: the classes of meatiness (S=1, E=2, U=3, R=4, O=5, P=6); the classes of fattiness (1=1, 2=2, 3=3, 4=4, 5=5). All the studied bulls (n = 485) were slaughtered and evaluated in a slaughterhouse by a classifier. The age at the slaughter and the daily net gain had a highly significant (P < 0.01) effect on meatiness. The best meatiness was found at the bulls slaughtered at the age from 751 to 820 days and from 651 to750 days (2.53 and 2.35). On the other hand the worst meatiness (3.11) was found at the bulls slaughtered at the age from 450 to 550 days. The best meatiness (class E) was found within the bulls with daily net gain from 641 to 720 g. On the contrary the worst meatiness was fond at the bulls with the top daily net gain 480 g. The carcass weight had a highly significant (P < 0.01) effect on fattiness. The lowest fattiness (2.05) was found at carcasses with the maximum weight 31kg but on the other hand the highest fattiness (2.48) was found at the carcasses with the weights from 351 to 400 kg.
