Abstract

18 male suckling lambs 11-13 kg live weight of Lacaune breed have been studied in order to evaluate the impact of lairage time of 0, 3 and 6 hours at slaughterhouse: on the behavioural indicators of animal welfare (standing or moving, lying and number time of drinking) and plasma parameters of physical stress (lactate) and psychological stress (total protein and cortisol). Lambs housed in the lairage had significantly higher levels of lactate (P <0.01) than those lambs slaughtered immediately (0 h) as a result of increased energy expenditure. The parameters of behaviour show that the lambs were lying longer in the first three hours of lairage that in the last ones (P <0001), without significant differences between the lots of 3 and 6 hours. The results of this study indicate that the welfare of suckling lambs is affected by the lairage time, and this lairage should be reduced as much as possible.
