Resumen:
The objective of the present study was to evaluate the effect of acute pre-slaughter stress on the quality of aged beef from animals raised and finished in contrasting production systems. The electrophoretic protein patterns (SDS-PAGE in gradient) indicated that muscle proteolysis was significantly altered in the meat of those animals submitted to the higher stress level for both feeding systems. Considering the absence of dark-cutting and normal pH 24 h of these muscles, it could be assume that the altered proteolysis is related to pH independent mechanisms.
