Abstract

Systems that objectively assess beef carcasses are becoming more common in slaughterhouses. The objectives of this study were to investigate differences in the EUROP classification of beef carcasses between independent national senior assessors and abattoir assessors, and to investigate the results of calibration and validation tests for the German VBS 2000 system in Poland. All the procedures involving calibration sample analysis and the certification test were conducted in accordance with the guidelines of Commission Regulation (EC) No. 1249/2008. The results show that evaluations provided by abattoir assessors significantly differ to those given by national assessors (P < 0.01), and that fat class is the best predictor of differences in EUROP evaluations. Pearson’s correlation coefficients for the median of evaluations from five assessors and evaluations from the VBS 2000 system were high for both conformation and fat classes: 0.905 and 0.907, respectively. A strong linear correlation between evaluations of conformation and fat obtained from assessors and the VBS 2000 system was found. Remuneration for livestock producers depends on the assessment of carcasses, and therefore, the evaluation process should be improved with an increase in the precision of carcass classification, and automated technologies give such possibility.
