[Histological studies on the capillarization of various muscles in industrially raised rabbits]

The longissimus dorsi, semitendinosus, psoas major and biceps femoris muscles of 40 industrially kept rabbits were studied in regard to their numbers of capillaries per square mm. The relation between the number of capillaries and muscle fibres is narrower in a red muscle than in a white one. The total body mass is of more influence on the number of capillaries per square mm than the age.
