The objective of the study was to determine the level of Bruising and Dark Firm Dry on Arsi, Boran and Harar cattle breeds in Ethiopia. A total of 39 beef bulls from three different breeds (14 Boran, 14 Harar, and 11 Arsi cattle breeds) were used in this study. Based on the present finding, from 39 slaughtered beef bulls 66.7% was bruised and 30.77% produced DFD meat. Harar breed had the highest (39.1%) overall level of bruising while Boran and Arsi had the lowest level. However, Harar breed had the lowest level of DFD (14.29%). Age groups 3 - 6 and 6 - 9 years had the highest level of a bruise (29.70% and 28.10%, respectively) compared to age groups 2 - 3 years. The mean number of bruises per carcass was 1.96 ± 0.25 while the bruise score per carcass was 3.58 ± 0.68. A linear bruise was the most observed (33.33%) shape of a bruise. It was concluded that the level of bruising and DFD was higher compared to some other abattoir studies in other countries which indicated the possible presence of poor handling practice of cattle from farm to abattoir gates. To minimize the incidence of DFD and bruising, it was recommended that proper handling of cattle during loading, transport, unloading, at lairriage and during slaughter need to be practiced.
