The experiment was carried out to evaluate the influence of different breed of sheep (West African Dwarf WAD, Ouda, Balami) and three different post-mortem dressing methods (scalding, singeing, and skinning) on the carcass, physical properties, organoleptic properties keeping quality of mutton in a factorial arrangement. Significant differences were recorded for both the strain and processing methods effect on the carcass characteristics and primal cuts. Balami strain of sheep yielded highest significant values (p<0.05) on all the primal cuts except rack and leg cuts which their values are closely related. Highest and lowest significant (p<0.05) values were observed for carcass weight (%) in both scalding (43.12) and singeing (37.90) while similar values (p>0.05) were recorded for Ouda and Balami breeds in cooking loss and cold loss (%) but least significant (p<0.05) value was noticed for Balami in terms of drip loss (4.96). Strain and processing methods does not influence (p>0.05) pH significantly, however significant (p<0.05) values were obtained when pH were observed at intervals (0, 30 and 60 mins). On the organoleptic properties, significant differences (p<0.05) were recorded in both the strain effect and processing methods as Balami and scalding method possess the highest significant (p<0.05) values in colour, juiciness, texture, flavor and overall acceptability except for tenderness that was not influenced (p>0.05) significantly by different post-slaughter dressing methods. total bacteria count (TBC) was reported at lowest significant level for WAD (1.23 x 1018cfu/g) and scalded mutton (1.24 x 1018cfu/g) at 0hr post-mortem however Balami strain and scalding method maintained the least significant (p<0.05) total bacteria count throughout the storage days (>0hrs to 13weeks). Conclusively, Balami breed of sheep and scalding method of post-mortem dressing gave promising and preferred results in all the quality parameters and are hereby advocated.
