Sex and animal behavior on yield and bruises in different beef cuts
The objective of this study was to examine the effects of behavioral differences in cattle on bruising on different cuts and on carcass yield. A total of 4,061 lots of cattle were evaluated, which corresponded to 199,026 carcasses. Animal temperament was classified as calm, anxious, or excited. The...

The objective of this study was to examine the effects of behavioral differences in cattle on bruising on different cuts and on carcass yield. A total of 4,061 lots of cattle were evaluated, which corresponded to 199,026 carcasses. Animal temperament was classified as calm, anxious, or excited. The following carcass cuts were evaluated: round, rump, shin, thin flank, tenderloin, and rib. Of the total number of slaughtered animals, 68.26% had at least one type of bruise with complete removal of the affected tissue. There was an interaction effect between sex and temperament on the occurrence of bruises on the different cuts and on carcass yield. In castrated males, bruises on the round, rump, shin, and tenderloin cuts did not differ between temperament classes, but the excited males showed more bruises on the thin flank and rib cuts. Among the females, for all cuts, the number of bruises was higher (P<0.05) in those with excited temperament than in the anxious and calm animals, which did not differ (P>0.05). Additionally, carcass yield relative to plant weight decreased (P<0.05), with the calm females exhibiting the highest values, followed by those with anxious and excited temperament. In the castrated males, however, although performance declined, those with anxious and excited temperament did not differ (P>0.05). Females and more reactive animals have more bruises on their carcass.
