Contenido: 	Abstract: Sixty Hereford (H) and Braford (B) steers were assigned to two diets: D1) native pasture plus corn grain (1 % of live weight) (H n=15, B n=15); and D2) high quality pasture (H n=15, B n=15) for finishing purposes. Temperament was individually assessed and monitored during the experiment. All animals were slaughtered the same day in two groups (50 % of animals from D1 and 50 % from D2 in each group) after staying 15 and 3 hours in lairage pens, respectively. Different physiological indicators were used to assess stress after transport, lairage and immediately preslaughter. Carcass quality was determined through the incidence of bruising and final pH. Calmer animals had higher average daily gains (ADG) with no differences between diets. Transport was not a psychological stressful stage but animals were physically affected. The group that remained 3 hours in lairage pens showed a higher
frequency of negative behaviour. These stressed animals did not have enough time to cope with the environment, with the consequent deleterious effects on final pH. The long lairage group had a higher metabolic response but these animals could rest and recover, and reached adequate final pH values. Braford steers were more excitable during the finishing period and also during lairage. Regardless of breed, temperament appears to be a valid tool for increasing productivity and decreasing the physiological stress response during all preslaughter stages. Further research should be carried out to establish the proper intermediate lairage duration according to animal welfare, and carcass and meat quality criteria.
