Description
Summary:The aim of this series of experiments was to examine the opportunity of application of X-ray Computer Tomography (CT) in cattle production. Altogether 191 animals of different breeds and genders were used in the study. In Experiment 1, the tissue composition of cuts between 11-13th ribs (n=136), was determined by CT and correlated with tissue composition of intact half carcasses prior to dissection and tissue separation. Results indicate that tissue composition of rib samples determined by CT closely correlates with tissue composition results by dissection of whole carcasses. In Experiment 2, tissue composition of rib samples by CT (n=40) were compared to the results of EUROP carcass classification. CT analysis has higher predictive value in estimation of actual tissue composition of cattle carcasses than EUROP carcass classification. The results of Experiment 3 showed that calves with higher muscle tissue area at the age of 7 days determined by CT will also have more meat in carcass. On the other hand, the cross sectional area of longissimus muscle can be used as a useful reference scan for the evaluation of meat of carcass.
