Meat quality characteristics of Bafra ram lambs slaughtered at different weights were investigated. A total of 24 lambs fattened intensively was slaughtered at four slaughter weights of 30, 35, 40, and 45 kg. Water-holding capacity, cooking loss, tenderness, color, as well as protein content did not vary significantly among the slaughter weight groups, although the 30-kg slaughter weight lambs displayed the greatest postmortem pH fall in musculus longissimus dorsi (P < 0.05). As slaughter weight increased, intramuscular fat of musculus longissimus dorsi showed an increasing nutritive value (P < 0.05), total unsaturated fatty acids/saturated fatty acids ratio (P < 0.05), and n6/n3 ratio (P < 0.05). However, atherogenic index and thrombogenic index values decreased with increasing slaughter weight, although this effect was not significant. The effect of slaughter weight on total cholesterol was not pronounced.
研究了不同体重屠宰的巴夫拉公羊羔羊的肉质特性。总共24只集约化育肥的羔羊在30、35、40和45千克四个屠宰体重下进行屠宰。尽管30千克屠宰体重的羔羊在背最长肌中表现出最大的宰后pH下降(P<0.05),但屠宰体重组之间的持水力、烹饪损失、嫩度、颜色以及蛋白质含量没有显著差异。随着屠宰体重增加,背最长肌的肌内脂肪显示出营养价值增加(P<0.05)、总不饱和脂肪酸/饱和脂肪酸比率增加(P<0.05)以及n6/n3比率增加(P<0.05)。然而,致动脉粥样化指数和血栓形成指数值随屠宰体重增加而降低,尽管这种影响不显著。屠宰体重对总胆固醇的影响不明显。
