Immunohistochemical and succinate dehydrogenase (SDH) activity-based classification of myofiber types in Krškopolje pig longissimus dorsi (LD) muscle. (A) Serial transverse sections of the LD muscle from pigs raised in the conventional indoor husbandry system (group C; A–D) or in organic conditions (group O; panels E–H) stained with the monoclonal antibodies (A,E) NLC-MHCs, (B,F) SC 71, and (C,G) BF-F3, specific for myofiber types I, II, and IIb, respectively; (D,H) succinate dehydrogenase (SDH) activity demonstrating the oxidative profile of myofibers. Scale bar, 200 μm is valid for all panels.
