Influence of temperament on performance and carcass quality of commercial Brahman steers in a Colombian tropical grazing system 2022 Access copy available to the general public Unrestricted Temperament is defined as individual behavioral responses to potentially fear-eliciting or challenging situations related to human presence and handling. A total of 190 steers of commercial Zebu Brahman (Bos indicus) were used in this study, selected when they were between 10 and 11 months of age, fattened for 24 months (720 days) and slaughtered between 34 and 35 months of age. Using a temperament index (based on two tests: chute and exit score), animals were classified as calm, restless, or nervous. In general, calm animals had a longer carcass, a higher slaughter and fasting weight, and a normal pH24 (<5.7). However, carcass yield was significantly higher in nervous than in restless animals, but did not differ from that of calm steers. It is important to note that these results were obtained under experimental conditions, therefore, effects could have a greater impact on carcass quality under commercial conditions. © 2022 The Authors info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 7.1 2022 FOOD SCIENCE & TECHNOLOGY 12 / 142 = 0.085 2022 Q1 T1 1.373 2022 Food Science 2022 Q1 12.6 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Flórez-Díaz, H.
