In December and January of two consecutive years
data was collected in two slaughterhouses (A and
B) of North Patagonia (Río Negro Province). Both
of them are qualified by the National Service of
Food and Agriculture Health (SENASA) to supply
meat along the national territory. In each
slaughterhouse a total of 5 batches of Merino
lambs of approximately 3 months of age were
chosen. Each batch of lambs was of the same age
and origin and had been transported and handled in
the slaughterhouse all together. The time of lairage
in holding pens was registered, but information on
transportation time could not be obtained. Twenty
lambs were selected at random from each batch

While animals were in the holding pens blood
samples were collected via jugular venipuncture to
determine urea (commercial kit, Wiener,
Argentina) and cortisol (ELISA method, kit
Diagnostic Systems laboratories, USA).
