Complex thermal environment has been identified as a major factor in the induction of physiological stress during transport. This paper presented some preliminary results of thermal conditions on commercial live haul trucks of three trips. Temperature and relative humidity were monitored at 30 selected locations during farm loading, transit and holding periods. Carbon dioxide concentrations, wind speeds on the trucks were also monitored. Large variation existed cross the truck in transit during the December trip when ambient temperatures were in the single digit. Less variation of temperatures were found during a day trip in January and a night trip in May. Fan operation under the shed was able to maintain temperature inside the truck not to exceed 6 C above the ambient condition.
