摘要

Sixty steers were finished on two different diets being slaughtered the same day in two groups (n=30) staying 15 (G1) and 3 hours (G2) in lairage pens. The aim of the study was to evaluate the effect of diet, temperament, transport and lairage time on animal welfare. Flight time was monthly registered. Stress was evaluated in blood by different indicators, after transport, after lairage and immediately pre slaughter. Behaviour was observed during lairage and carcass pH was registered at 24 hours pm. Data was analised by the SAS package. Calmer animals were less stressed at all pre slaughter stages. Transport did not imply psychological stress, but animals were physically affected. According to negative behaviour, the first hour in lairage was stressful, but animals became calmer afterwards. Noise at the abattoir was higher during the morning. Probably that, and the insufficient resting period in G2, remained animals excitable, contributing to glycogen depletion and a higher carcass pH. Animals from Gl had a higher metabolic stress response but steers had greater opportunities to rest/recovery showing a better carcass pH. Those results suggest that more than 3 hours pre-slaughter time should be necessary, depending on lairage conditions.
