Dressing percentage did not differ significantly due to breed or castration. However, adjusted mean dressing percentage revealed a significant breed effect. Baladi goats dressed better (adjusted mean percentage: 51.8) than Zaraibi goats (adjusted mean 47.9%). No significant breed effect was observed on dressing percentage based on empty body weight. Neither carcase weight nor carcase dimensions were significantly affected by breed or cast ration.
The effect of breed on percentages of carcase wholesale cuts was non-significant. However, castration caused a highly significant reduction in the percentages of neck, shoulder and rack cuts.
The weight of empty tripe, bluck and kidneys with their fat was significantly affected by breed. Zaraibi had heavier weights of these components. Castrated males had significantly smaller head, hide and larger spleen than entire males.
