Abstract

Histochemical properties of M. iliotibialis lateralis were compared between Kumamoto Cochin (a Japanese native breed) crossbred roasters (KC roasters, 112 d of age) and normal broilers (56 d of age). 2. Myofibres were divided into Types II-R, II-I and II-W showing high, moderate and low reduced nicotinamide adenine dinucleotide dehydrogenase (NADH-DH) activities, respectively. 3. Subsarcolemmal formazan granules indicating very strong NADH-DH activity in Type II-R fibres were observed only in KC roasters. In both sexes the percentage of Type II-R fibres present was greater in KC roasters than in broilers. 4. These results indicated marked differences in histochemical properties and meat quality between KC roasters and broilers.

摘要

比较了熊本科钦鸡（一种日本本土品种）杂交烤鸡（KC烤鸡，112日龄）和正常肉鸡（56日龄）外侧髂胫肌的组织化学特性。2. 肌纤维分为II-R型、II-I型和II-W型，分别显示出高、中、低的还原型烟酰胺腺嘌呤二核苷酸脱氢酶（NADH-DH）活性。3. 仅在KC烤鸡中观察到II-R型纤维中肌膜下甲臜颗粒显示出非常强的NADH-DH活性。在两性中，KC烤鸡中II-R型纤维的百分比均高于肉鸡。4. 这些结果表明KC烤鸡和肉鸡在组织化学特性和肉质方面存在显著差异。
