The objective of this study was to compare in vivo and at slaughter performances and Longissimus thoracis (LT) composition of Goudali (G) and Goudali × Italian Simmental (SG) young bulls. Fifty G and SG reared entirely on native pasture in Northwest Cameroon and belonging to one farm were considered. Body weight (BW) of animals was recorded on-farm. After slaughter, the cold carcass weight and the fifth quarter composition were recorded, and the killing out percentage calculated on the reconstructed ante mortem BW (BWam). After 24 h a sample joint was removed from the 8th rib position, dissected in lean, fat and bone portion and the proximate composition was carried out. SG showed higher BW at farm, BWam, cold carcass weight and KO%, than G, but also a marked loss of weight during transfer and lairage time. SG had lower percentage of feet, tail, filled gut, and higher weight of rib steak, ribeye and percentage of lean tissue than G. Conversely, the LT composition was similar between breeds. Results suggest that performances and fat composition of LT of F1 crosses, SG, in comparison with the pure breed, G, could be further increased by improving the bull’s transfer and pre-slaughter conditions.

Abstract

The objective of this study was to compare in vivo and at slaughter performances and Longissimus thoracis (LT) composition of Goudali (G) and Goudali × Italian Simmental (SG) young bulls. Fifty G and SG reared entirely on native pasture in Northwest Cameroon and belonging to one farm were considered. Body weight (BW) of animals was recorded on-farm. After slaughter, the cold carcass weight and the fifth quarter composition were recorded, and the killing out percentage calculated on the reconstructed ante mortem BW (BWam). After 24 h a sample joint was removed from the 8th rib position, dissected in lean, fat and bone portion and the proximate composition was carried out. SG showed higher BW at farm, BWam, cold carcass weight and KO%, than G, but also a marked loss of weight during transfer and lairage time. SG had lower percentage of feet, tail, filled gut, and higher weight of rib steak, ribeye and percentage of lean tissue than G. Conversely, the LT composition was similar between breeds. Results suggest that performances and fat composition of LT of F1 crosses, SG, in comparison with the pure breed, G, could be further increased by improving the bull’s transfer and pre-slaughter conditions.
