title: Comparative studies on the histochemical properties of M. iliotibialis lateralis from Kumamoto Cochin crossbred roaster and broiler chickens.
abstract: 1. 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.
