摘要
The slaughter and carcass features of four breeds named Limousin (LI), Charolais (CH), Angus (AN), and Hereford (HE) were examined. Nine calves from each breed were slaughtered at an average age of 18.5 months. The animals were weighed before slaughter, and the slaughter weights as well as some body measurements of the animals were recorded. The dismemberment of the carcasses was performed after a resting period of 24 h at + 4 °C. The slaughter weights were 581.89, 590.72, 577.67, and 610.89 kg, respectively. Chilled carcass weights were 348.26, 346.91, 327.60, and 338.10 kg, respectively, with no significant differences among breeds. Dressing percentages were 59.89, 58.75, 56.71, and 55.33%, and the valuable meat ratios were 27.89, 27.66, 24.45, and 24.32%, respectively. Carcass bone ratios were 13.89, 14.17, 14.64, and 14.61%, respectively. The longissimus muscle areas (LMA) were 97.46, 102.29, 81.05, and 83.93 cm2, and the subcutaneous fat thickness was 0.38, 0.43, 1.00, and 1.32 cm, respectively. Significant differences were observed among breeds in terms of these characteristics. Carcass weight was highest in LI, and LI and CH breeds had higher carcass yields than the other two breeds. Although HE had the highest slaughter weight, it showed the lowest carcass yield. Whilst more meat was obtained from LI and CH, the highest fat and bone ratios were determined in HE and AN.

检查了四个名为Limousin（Li），Charolais（CH），Angus（An）和Hereford（He）的屠杀和尸体特征。每种品种的九只小牛在平均年龄为18.5个月的平均年龄被宰杀。在屠宰前称重动物，并记录屠宰重量以及一些身体测量。在+4°C下的静止期24小时后进行尸体肢解。屠宰重量分别为581.89、590.72、577.67和610.89公斤。冷藏的尸体重量分别为348.26、346.91、327.60和338.10 kg，品种之间没有显着差异。敷料百分比为59.89、58.75、56.71和55.33％，有价值的肉比分别为27.89、27.66、24.45和24.32％。骨体骨比分别为13.89、14.17、14.64和14.61％。Longissimus肌肉区域（LMA）分别为97.46、102.29、81.05和83.93 cm 2 ，皮下脂肪厚度分别为0.38、0.43、1.00和1.32 cm。在这些特征方面，品种之间观察到了显着差异。li中的car体重量最高，Li和Ch品种的car体产量高于其他两个品种。尽管他的屠宰重量最高，但表现出最低的car体产量。虽然从LI和CH获得了更多的肉，但在HE和AN中确定了最高的脂肪和骨比。
