摘要

Fibers of the external obturador (1) and long of the neck (2) were analyzed in swine, of four genetic group. Histoenzymological techniques were employed (HE, acid mAtpase, pH 4,6 and NADH-TR). This allowed classification as to metabolism type and muscular contraction type. It was concluied that muscle 1 possesses more than 50% of FG fibers and muscle 2 more than 40% of SO fibers. Both presented a larger percentage of fast contraction fibers. Regarding metabolism, muscle 1 has a glycolitic (anaerobic) while 2 has an oxidative (aerobic) character.
