Abstract: A total of 170 carcasses of bulls aged between 14 and 26 months were studied for their characterization in terms of conformation and fatness degree using morphometric measurements. The slaughtered bulls are mainly Holstein, Limousin, Charolais and Crossbred beef. Carcass measurements performed at the slaughterhouse were length of the carcass, perimeter of the hind leg, depth of the carcass, length and thickness of the hind leg. Hot carcass weight, thickness of fat cover at the sixth rib and kidney fat weight were recorded. Carcass characterization was performed using principal component analysis and cluster analysis using Ward Method. The results showed the existence of four groups of carcassec: with a low conformation and a small frame size. Carcasses with an average conformation and a large frame size. Carcasses with a fairly good conformation and a small frame size. Carcasses with a good conformation and a large frame size. In conclusion, this study provides valuable information for the characterization of carcasses of bulls slaughtered in Tunisia. It also provides useful information for establishing a beef carcass classification grid in an attempt to meet the needs of the red meat sector operators and allows a balance between the price and the quality of marketed carcasses.
