The present study was carried out at the slaughterhouse in the town of Korhogo to assess the morphological characteristics and quality of sheep carcasses. For this purpose, all sheep admitted to the slaughterhouse were considered. On these animals, different parameters such as determination of age, sex, live weight and body condition score were evaluated before slaughter. The criteria for assessing the quality of the carcasses (state of fattening, conformation and coloring, carcass weight and yield), carried out according to evaluation grids after slaughter. The results showed that Djallonke sheep were the most slaughtered in this slaughterhouse (91.3% of total numbers), including females over 4 years old (37.1%). However, Sahelian breed sheep had a higher carcass yield (47.93%) (P ≤ 0.05) than that of the Djallonkes (46.16%). The carcasses were mainly category D (83.77%) and conformation E (41.15%). However, the proportion of red coloring carcasses was highest in the Djallonké breed (64.97%) than in the Sahelian breed (5.92%). From the analysis of these results, it appears that most sheep admitted to the Korhogo slaughterhouse are females who have not finished their career in extensive breeding. Which could be detrimental to the sustainability of farms.
