Abstract
The offal is well appreciated by consumers in sub-Saharan Africa and viscera are sold at the same price as the carcass meat. Therefore, the aim of this study was to assess on the offal components yield of Lagunaire, Borgou and Zebu Fulani bulls raised on natural pasture and to examine the macroscopic lesions associated with potential hazards for the consumer. Offal was collected from the slaughterhouse of Cotonou-Porto-Novo in 40 Lagunaire, 71 Borgou and 110 Zebu Fulani bulls. The Zebu bulls offal weight and offal components weight were significantly higher than those of the Borgou bulls (p<0.001), whereas the Lagunaire bulls level were the lowest (p<0.001). The Zebu Fulani offal percentage was heavier, followed by the Borgou bulls whereas the Lagunaire had a higher head percentage and a higher offal percentage in the carcass. During the rainy season, the viscera weights of Borgou and Zebu bulls were higher than during the dry season; they were characterized by a higher external offal weight. Nevertheless, the Lagunaire bulls were weakly discriminated whatever the season. The offal components were condemned for 20 affections or diseases at the post mortem inspection. The main causes of lungs seizure were tuberculosis (43.04%) and pulmonary emphysema (21.41%). The diaphragm was also affected by tuberculosis (93.3%) and scarcely by abscess (3.70%). Livers were affected by fascioliasis (41.43%), dicrocoeliasis (22.92%) and tuberculosis (15.77%). Spleen
