The authors acknowledge,however,that it is difficult to attribute
DOAs precisely to a specific part of the process of handing and transport.Under commercial
conditions it is difficult to establish the causes of mortality in transport and there are few studies
available that have provided such information.Nevertheless,Hunter et al.(1997) examined the
distribution of mortalities on commercial broiler transport vehicles and reported a significant link
between the on-board thermal micro-environment and DOA values.Mortality was highest in those
parts of the vehicle where temperatures and humidities were greatest or where the ingress of cold air
and water resulted in cold stress.Postmortem examination indicated that an underlying level of
randomly distributed DOAs on the vehicles encountered on journeys at all times of the year could be
attributed to existing pathologies and/or catching injuries.
