Conditions (total complex of stressors) during the transport of animal
s vary strongly between and within transports. Adverse climatic condit
ions are stressors that animals have to face during transport; The the
rmoregulation of animals is discussed with respect to threshold values
for optimal climatic conditions. These thermal thresholds depend on a
nimal related factors and environmental conditions. The specific impac
t of transport conditions, such as food and water deprivation, high st
ocking density, high humidity and high air velocity, on thermal thresh
olds are described.
