Carcass characteristics were studied in two groups of 6 and 4 Janoubi bulls slaughtered at the age of 18 and 24 months, respectively. Slaughter body weight, carcass weight hindquarters weight and rib eye area were significantly higher (P0.01) in the group of 24 months old. Forequarters weight, weight of head, heart, testicles and kidney fat were also higher (P0.05) in the older group of animals. Other offal and soft organs weight did not show significant difference among the two groups of age. Dressing percentage of the 24 months old animals was superior (P0.05) to those of 18 old. Weights of offal and soft organs as percentages of live body weight were not significant. Age at slaughter had no effect on percentages of dissected lean, fat and bone. While percentage of moisture was lower and percentages of protein, ash and ether extract were significantly higher (P0.05) in the longissimus muscle of the animals slaughtered at 24 months old in comparison with animals slaughtered at the age of 18 months
