Space required for different body, positions was investigated for sheep of different weight and genetic background in undisturbed housing conditions. Body temperature, as stress indicator, was measured at different intervals during transport. The loading situation caused a distinct increase; a slight increase was measured after unloading. During transport, the values did not reach those taken before loading. Concerning the space required for resting, the present results indicate that sheep (weighing between 32 and 35 kg) being transported with a space allowance of 0.16, 0.26, 0.27, 0.42 and 0.45 m2/animal showed an appreciable amount of resting behaviour only at lower densities, i.e. with space allowance of more than 0.40 m2. The recommended space allowance by the EU of 0.21 to 0.23 m2 for sheep of this weight group has to be considered as too low to permit effective resting behaviour. The problem of supplying sheep with water and feed during transport has not yet been solved. The question is not only how much space the animals need for feeding but also a matter of the technical equipment for supplying feed and water so that all animals are able to reach it.
