| ABSTRACT Thirty ram lambs of native breeds (10 of each Ossimi, Barki and Rahmani), fattened up to 12 months old, were used to investigate the influence of breed and body weight on body measurements and carcass traits. Heart girth and paunch girth of Barki ram lambs were significantly (P < 0.05) higher than those of Ossimi and Rahmani ones. Liver weight was significantly (P < 0.05) heavier in Barki ram lambs than in Ossimi and Rahmani ones. Carcass of Ossimi significantly (P < 0.05) excelled that of Barki and Rahmani breeds in total fat stores. Whereas, Barki carcass had significantly (P < 0.05) less total fat content. The superiority of Ossimi breed in total fat stores may be due to its heaviest fat tail. Accordingly, hot carcass weight was the highest in Ossimi ram lambs (26.1 kg) followed by Barki ones (25.8 kg). Whereas, Rahmani ram lambs produced significantly (P < 0.05) the lowest hot carcass weight (24.3 kg). Hence, the highest dressing percentage was significantly (P < 0.05) found in Ossimi carcass (56.2%) which was over Barki (53.3%) and Rahmani (53.1%) carcasses. However, the highest weights of carcass cuts (round, loin, thoracic region, shoulder, neck and flank) were recorded in Barki carcass compared with those of Ossimi and Rahmani ones. One the other hand, body weight of ram lamb exerted a positive and highly significant (P < 0.01) effect on all body measurements and weights of all internal offals (except spleen), hot carcass and all carcass cuts. Meanwhile, neither breed of sheep nor body weight of ram lamb had a significant effect on Longissimus dorsi area. It could be deduced that Barki ram lambs raised under intensive production system had the best carcass traits with less fat content | ||
