Abstract

Using adult Silkie and White Leghorn (WL) chickens, fibre composition and total collagen content were compared between M. iliolibialis 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.

摘要

以成年乌骨鸡和白来航鸡为实验对象，比较了股外侧髂胫肌（ITL）和胸肌（PT）的纤维组成及总胶原蛋白含量。2. 纤维分为IIR型和IIW型，分别显示出强和弱的还原型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型和IIW型纤维组成，而PT肌仅由IIW型纤维组成。仅在公鸡的ITL肌中发现了品种组成差异（IIR型；乌骨鸡为53.8%，白来航鸡为37.0%）。4. ITL肌以及两种肌肉中的公鸡总胶原蛋白含量更高。然而，仅在母鸡的PT肌中观察到品种差异。5. 总之，总胶原蛋白含量受身体内肌肉位置和性别的影响，而非纤维组成的影响。
