Abstract
In a 2x2 factorial design, (n=6) sheep were either transported by road for 15h or kept in their home pens, and then either starved for 12h with access to water or offered hay ad libitum, with access to water. All groups were offered hay and water 12h after transport. Behavioural observations and mea surements of dehydration and feed restriction were made before, during, and for 24h post-transport, to evaluate the implications of these procedures f or the welfare of sheep. After the journey, the immediate priority for the sheep was to eat. Consump tion of hay increased water intake and reduced the time spent lying down. T he plasma cortisol concentration was greater in sheep which had been starve d during the 12h post-transport period, than in those offered hay during th is time; and the plasma free fatty acid concentration was greater in sheep which had been transported than in those which had not. Although transporte d sheep kept without hay during the first 12h post-transport drank more wat er than those which had not been transported, the mean time before they dra nk was greater than 7h. During the transport period, there was less lying b ehaviour in transported sheep than in non-transported sheep but transported sheep did not lie down more post-transport than non-transported ones. This work suggests that sheep should be offered both feed and water after a 15h journey. However, when feed was not available after a 15h journey drinking and resting did not appear to be immediate priorities.
