The objective of this study was to determine sex effects on blood stress indicators, muscle glycolytic potential and mutton quality. Blood samples were collected at exsanguination for measurements of glucose, lactate and cortisol levels. Representative meat samples were collected from the Muscularis longmissius thoracis et lumborum for the measurements of glycolytic potential, pH and color co-ordinates. Sex had an effect on blood lactate, cortisol levels, meat pH and colour co-ordinates, but not on muscle glycolytic potential. Ewes had higher levels of blood lactate, cortisol, pH and colour than the rams. High levels of blood stress indicators and meat pH are an indication that the ewes experienced the pre-slaughter period to be more stressful compared to the rams.
