摘要：

The objective of the study was to evaluate, according to EUROP grading system, the slaughter value of cattle of different categories supplied by commercial stock producers. Included were 38 576 animals purchased in the year 2005 by one of the biggest meat processing plants in the central-eastern Poland. The assessment of meat content of carcass and carcass fatness according to EUROP grading system covered 3 613 heifers, 15 712 cows and 19 251 young bulls. The hot dressing percentage was determined in 2 922 animals representing three basic meatiness classes, ie. U, R and O. Established was also the weight and share of carcass perirenal fat (kg) and subcutaneous fat thickness (mm) in 100 animals from each analysed bovine category (Le. heifers, cows and young bulls. It was found that in each cattle category examined, the highest number of carcasses belonged to class 0 (54.37-84.85%), while the fatness assessment put majority of them to class 2 and 3. In each commercial class of the EUROP system the young bulls showed significantly highest hot carcass weight as well as the highest hot dressing percentage (53.7-56.8%). Heifer carcasses demonstrated the thickest subcutaneous fat (12.0 mm), whereas the thinnest was reported in young bulls (5.4 mm). In heifers and cows a higher perirenal fat weight was recorded as compared to young bulls (P < 0.05).
