[Changes in the distribution of muscle fiber types in the M. longissimus dorsi of boars during growth, prepared by different histochemical methods]

Samples of the M. longissimus dorsi from growing up pigs were taken by a shooting-biopsy. The types of muscle-fibers could be demonstrated by two different histochemical staining procedures. With these two histochemical staining procedures significant differences between the different structure of the muscle-fibers during increasing age of the pigs could be detected.
