ABSTRACT: This study was conducted with the objective to determine carcass traits,
meat yield, and primal meat cuts of Arsi, Harar, Jersey*Horro crossbred, and
Ogaden cattle breeds at Haramaya University, Ethiopia. A total of 12 bulls of
four cattle breeds (3 Arsi, 3 Harar, 3 F1 Jersey*Horro crossbred and 3 Ogaden) with almost similar ages were randomly assigned to
four treatments in a completely
randomised design (CRD). Data on carcass traits, meat yield, and primal
meat cuts were analyzed using the General Linear Model (GLM) of the Statistical
Analysis Software (SAS) 9.4 version. The overall averages of live body weight,
hot carcass weight, chilled carcass weight, dressing percentages based on hot carcass weight, and rib eye area of
experimental cattle breeds were 215.58 kg, 102.93 kg, 99.56 kg, 47.61%,
and 8.13 inch2, respectively. The hot carcass weight and chilled
carcass weight of the Ogaden (136.57; 133.30 kg, resp.) breed were higher (p %, 45.27%, resp.) cattle breeds. The average meat
yield and proportion of meat yield of cattle breeds were 77.52 kg and 77.46%, respectively. With a linear regression
coefficient of prediction (R2) ranging from 52.26% to 93.58%,
primal meat cuts significantly (p dicted meat yield. In
conclusion, the breed of cattle had a significant (p 0.05) influence on live body weight, hot and
chilled carcass weight, dressing percentage, rib eye area, subcutaneous fat
thickness, meat yield, and the weights of most primal meat cuts. The Ogaden
cattle breed had a higher and better meat yield, carcass traits, and most
primal meat cuts compared to other experimental cattle breeds. Furthermore, the
inclusion of corn silage in the diet of fattening bulls improved the carcass
and meat yield. Therefore, the performance of Ogaden cattle compared to other
and previous studies suggests the possibility of using this breed for export
purposes in addition to Borana and Harar cattle breeds in the future.
