Comparative Morphometric Analysis of Longissimus dorsi Muscle Structure in Wild and Domestic Pigs

Mirela E. CADAR


There were done morphometric determinations on longissimus dorsi muscle as
proportion of type I, IIA and IIB muscular fibers, fiber diameter, transversal section area and
relative area of fiber types. The samples were prepared as histological transversal sections on which
was marked out the succinate-dehydrogenase activity.
We observed that in wild pigs, comparatively to those domestic ones of Large White breed,
the red fibers (type I and IIA) are more numerous, thicker and their relative area is superior to those
one in domestic pigs.
