通过测定背最长肌、半腱肌和尺侧腕伸肌的羟基吡啶和羟基吡啶含量，研究了肌肉胶原交联的形成。这些样本取自雄性、雌性和阉割的德国西门塔尔牛（150-620日龄），它们在不同的能量水平上被育肥，并与性别、喂养强度和肌肉类型的可能影响有关。在肌内胶原蛋白中，发现与年龄相关的吡啶啉含量增加。交联的形成也受性别和摄食强度的影响。Epimysia表现出吡啶碱含量的差异，这可能是由于肌肉物理应变的差异。
Development of muscle collagen cross-linkage was investigated by determining hydroxylysylpyridinoline and lysylpyridinoline contents of longissimus dorsi, semitendinosus and extensor carpi ulnaris muscles. These were removed from male, female and castrated German Simmental cattle (150-620 days old) fattened on different energy levels and related to possible influences of sex, feeding intensity and type of muscle. In intramuscular collagen, an age-related increase in pyridinoline content was found. Cross-link formation was also influenced by sex and feeding intensity. Epimysia exhibited differences in pyridinoline content which were probably due to differences in physical strain of the muscles.
