Histological Analysis Of Selected Muscles In Ostrich ( Struthio camelus var.dom.)

We found that the percentage of individual muscle components show statistically significant differences in all analyzed muscles. More α-red fibers were found in m. iliotibialis lateralis and m. femorotibialis externus, while abundance of white (α-white) muscle fibers was very low. Unlike other species of birds (turkey, chicken, geese) in all studied muscles, proportion of all red fibers (a-red and b-red) greatly exceeded the proportion of white muscle fibers (a-white ). Adipose tissue content in individual muscles ranged from 0.0% (m. iliotibialis lateralis) to 1.67% (m gastrocnemius).
