Critical points in the pre-slaughter logistic chain of lambs in Spain that may compromise the animal's welfare

This study identifies critical points of lamb transport to slaughter in Spain with regard to handling before, during and after transport. Special emphasis was given to the effect of classification centres (i.e. temporary feedlots). Farmers (n = 60), hauliers (n = 30), abattoirs (n = 20) and classification centres (n = 11) were surveyed. Data were collected on methods and facilities used for loading and unloading, transport times, types of vehicle(s) and abattoir practices. The average journey time was 131 ± 74 min, with a mean transport distance of 110 ± 79 km. In general, the logistic transport chain for lambs seems to be acceptable. This is partly demonstrated by the low incidence of DFD meats <5%. However, the classification centres (CCs) represent the weakest part of the logistic chain, because of social mixing due to regrouping and double transportation. In consequence it is necessary to develop a decision support system to assess animal welfare along the logistic chain.
