Withdrawal periods corresponded to EU transport regulations, which allow sheep and goats to be transported for a maximum period of 14 hours, followed by a rest period of at least one hour sufficient for them to drink water, if a further 14-h travel is necessary. In the present study tools for authorities to approve the offer of water were evaluated. Fifteen Boer goats and 1 Blackhead mutton sheep were assigned in a 3 x 3 Latin square design to 1 of the following treatments: AL (ad libitum), SHORT (14 h withdrawal – 1 h access – 14 h withdrawal) or LONG (29 h withdrawal). The study was conducted under stable conditions without transporting the animals. Haematological parameters were analysed at 0, 14, 15, and 29 h. Standing, lying, and feeding behaviour were recor ded. In sheep, LONG had lowered packed cell volume (PCV) compared with AL- and SHORT-animals at 14 h (P  lt; 0.05). Serum sodium (Na) was higher in SHORT- and LONG- than in AL-group at 14 h (P  lt; 0.05), and higher in LONG than in both other groups at 29 h (P  lt; 0.05). During 0–14 h sheep fed  gt; 20 min/h and ~5 min/h during 1–29 h (P  lt; 0.05). In goats, the SHORT- (at 14 and 15 h) and LONG-group (at 29 h) showed greater haemoglobin values when compared with the AL-group (P  lt; 0.05). Serum Na increased from 0 to 14 h in SHORT- and LONGgroups (P  lt; 0.05). Total feeding time was similar to sheep  gt; 20 min/h during  0–14 h and ~5 min/h during 15–29 h (P  lt; 0.05). In conclusion, the tested parameters showed only limited potential to monitor the fulfilment of transport regulations.  a0005-9366
