چکیده انگلیسی
The influence of hide color and sex on carcass grading performance and value was evaluated on 18,575 carcasses. Cattle exhibited color frequencies of black (50.0%), black-white face (10.6%), red (10.6%), red-white face (5.8%), gray (4.9%), yellow (4.7%), white (3.5%), Holstein (2.7%), striped (2.4%), yellow-white face (2.2%), gray-white face (1.4%), and spotted (1.3%) and sex frequencies of 83.5% steers and 16.5% heifers. Black cattle (black and black-white face) had greater (PÂ <Â 0.01) s.c. fat (1.46Â cm), hot carcass weight (HCW; 362.4Â kg), KPH (2.38%), calculated YG (3.30), and marbling score (Small29) with less (PÂ <Â 0.01) LM area (83.9Â cm2) than did nonblack cattle (red, red-white face, gray, gray-white face, yellow, yellow-white face, white, striped, spotted, Holstein) (1.24Â cm, 357.2Â kg, 2.34%, 2.89, Small02, 86.9Â cm2, respectively). Steers had less (PÂ <Â 0.01) s.c. fat (1.18Â cm), KPH (2.22%), calculated YG (2.83), and marbling score (Slight98) with greater (PÂ <Â 0.01) HCW (372.3Â kg) and LM area (89.4Â cm2) than did heifers (1.37Â cm, 2.47%, 3.11, Small19, 344.0 Â kg, 83.4Â cm2, respectively). Black cattle had greater (PÂ <Â 0.01) HCW discounts (-$1.32), YG discounts (-$2.46), and market value ($122.93) with less (PÂ <Â 0.01) QG discounts (-$2.07) than did nonblack cattle (-$1.10, -$1.73, $122.49, -$3.46, respectively). Steers had less (PÂ =Â 0.02) HCW discounts (-$0.97) and (PÂ <Â 0.01) YG discounts (-$1.33) with greater (P < 0.01) QG discounts (-$3.68) than did heifers (-$1.43, -$2.30, -$2.56, respectively). The results suggest that the incentives to pay premiums for feeder cattle based on hide color diminish once the finished animal is in the carcass form and that steer and heifer carcasses have differing carcass characteristics that could warrant independent value-based marketing methods.
