Resumen:
Abstract ? Increased levels of stress hormones in the muscle could lead to post mortempost mortem
metabolic/structural modifications which could also be reflected on meat quality. Present study
investigated the metabolic effect of either adrenaline or cortisol injected into lambs. Results obtained
demonstrated increased glucose metabolism and increased muscle temperature linked to adrenaline
or cortisol injection. Muscle pH immediately post mortem was affected by adrenaline, but not by
cortisol injection. Final muscle pH and temperature were not affected by hormones injection. WHC of
fresh muscle was not altered neither by adrenaline nor by cortisol treatments. The animal model of
acute stress used succeeded in emulating a biological acute stress. Ageing studies of meat quality are in
progress in order to test the hormone effect on the development of meat quality.post mortem was affected by adrenaline, but not by
