This study was carried out at the Bukavu central slaughterhouse known as the Ruzizi II / ELEKAT public slaughterhouse. The aim was to evaluate the slaughtering performance of slaughtered cattle within this slaughterhouse, not only taking into account their provenance, but above all by relying on their genotype expressed in the format and system breeding. The zootechnical parameters were determined by the barymmetric method to take the size at the withers or the Ugandan zebu comes first, the oblique length of the trunk of the animal or it is the Rwandan zebu that comes before and the thoracic perimeter of which the bull has a high score, here it is Swiss brown. While the yield components consisted of weighing the animal before slaughter for live weight and after slaughter, the weight of the carcass. The results obtained showed that the genomic expression retains its value whereas the system of breeding plays little. It was found that the average zebu yielded a slaughter yield which was low by 44% followed by the small-size zebu with a yield of 46% at the time when the taurine reached a high yield of order of 49%. Nevertheless, it appears that the hazards of transport and food play on these results.

Abstract: (french)
Cette étude a été effectuée à l’abattoir central de Bukavu connu sous le nom de l’abattoir public Ruzizi II / ELEKAT. L’objectif était d’évaluer le rendement à l’abattage des bovins abattus au sein de cet abattoir, non seulement en tenant compte de leurs provenances mais et surtout en s’appuyant sur leur génotype qui s’exprime avec le format et le système d’élevage. Les paramètres zootechniques ont été déterminés grâce à la méthode barymétrique pour prélever la taille au garrot ou le zébu ougandais vient en premier, la longueur oblique du tronc de l’animal ou c’est le zébu rwandais qui précède et le périmètre thoracique dont le taurin a un score élevé, ici il s’agit du brun suisse. Tandis que les composantes du rendement consistaient à peser l’animal avant l’abattage pour connaître le poids vif et après l’abattage, le poids de la carcasse. Les résultats obtenus ont montré l’expression génomique garde sa valeur alors que le système d’élevage ne joue guère. Il s’avère que le zébu format moyen a donné un rendement à l’abattage qui est faible d’ordre de 44% suivi du zébu de petit format avec un rendement de 46% au moment où le taurin atteint un rendement élevé d’ordre de 49%. Néanmoins, il s’avère que les aléas du transport et de l’alimentation jouent sur ces résultats.
