Development of muscle collagen cross-linkage was investigated by determining hydroxylysylpyridinoline and lysylpyridinoline contents of 1ongissimus 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.
