The objective of this study was to calculate the risks (odds ratios) of occurrence of bruises on cattle carcasses in different animal categories. The study was conducted in a slaughterhouse plant, located at São Paulo state, Brazil. Data collection was carried out during one year, assessing 22234 cattle carcasses. To calculate the risk (odds ratios) of bruises occurrences on cattle carcasses the GENMOD procedure of SAS was used, considering logistic regression models.
