【摘要】 本研究测定 72头不同日龄段皖南花猪的肌肉品质 ,以分析皖南花猪肌肉品质的变化规律。结果表明 ,皖南花猪的肌肉 p H1 值在整个生长期内变化不大 ,一直维持在 6 .58～ 6 .30之间 ;失水率与月龄呈直线负相关关系 ,由初生时的 2 3.0 3%下降到 1 2月龄时的 7.0 0 % ;肉色、大理石纹、熟肉率、剪切力和肌纤维直径等指标则随着日龄的增加而逐渐提高 ,与月龄均呈显著的直线正相关 ,至 1 2月龄时 ,皖南花猪的肉色评分为 3.50 ,大理石纹评分为 2 .88,熟肉率为 6 3.91 % ,剪切力为 4 .4 3kg,肌纤维直径为 53.86 μm,其中肌肉剪切力和肌纤维直径在 1 -6月龄时的提高幅度较大 ,8-1 2月龄的上升趋势减缓更多还原

【Abstract】 The meat quality of 72 Wannanhua pigs in different days were measured in order to study their change patterns The results showed that the value of pH 1 remained stable (from 6 58 to 6 30) all along in every growing stage With the growing of pigs, the rate of water loss decreased gradually from 23 03% to 7 00%,while the indexes of meat color,marbling,cooking rate,tenderness and muscle fibers increased gradually The values of Wannanhua pig’s meat color and marbling in 360 days were 3 50 and 2 88 points respectively,at the same time, the cooking rate,shear value and diameter of muscle fibers were 63 91%, 4 43 kg and 53 86 μm,respectively Otherwise,the shear value and diameter of muscle fibers increased quickly from birth day to 180 days更多还原
