1.以成年乌骨鸡和白来航鸡为试验材料，比较了两种鸡的纤维组成和总胶原蛋白含量。2.将纤维分为IIR和IIW型，分别表现出较强和较弱的还原烟酰胺腺嘌呤二核苷酸脱氢酶活性。3.ITL肌和PT肌的纤维组成有显著差异。ITL肌由IIR和IIW两种类型的纤维组成，PT肌仅由IIW型纤维组成。品种间只有IIR、乌骨鸡和WL型公鸡的ITL肌肉成分存在差异(分别为53.8%和37.0%)。4.ITL肌和公鸡的总胶原含量均较高。然而，品种差异仅在母鸡的PT肌中观察到。5.总胶原蛋白含量受肌肉在体内的位置和性别的影响，而不受纤维组成的影响。
1. Using adult Silkie and White Leghorn (WL) chickens, fibre composition and total collagen content were compared between M. iliotibialis lateralis (ITL) and M. pectoralis (PT). 2. Fibres were divided into type IIR and IIW showing strong and weak reduced nicotinamide adenine dinucleotide dehydrogenase activities, respectively. 3. Fibre composition differed markedly between ITL and PT muscle. ITL muscle was composed of both types IIR and IIW fibre but PT muscle of only type IIW. Breed difference on composition was noted only in ITL muscle of cocks (type IIR; Silkie 53.8% and WL 37.0%). 4. Total collagen content was greater in ITL muscles and in cocks in both muscles. However, a breed difference was observed only in the PT muscle of hens. 5. In conclusion, the total collagen content was affected by muscle location within the body and by sex rather than by fibre composition.
