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.

答案

作者承认,不论如何,很难精确的把活禽死亡看做是管理和运输过程中具体的一部分.在商业条件下,很难确定运输死亡率的原因,尽管一些有效的研究已经证明了这些信息.然而,Hunter等人审查了肉鸡运输工具的死亡率分布并公布了保温车的微观环境和活禽死亡标准之间的重要关联.车上温度和湿度最高的地方以及造成冷应力的冷气和水的入口处死亡率是最高的.尸体检查表明在每年各个时期的车辆旅行中随机分布的活禽死亡的基本水平都可以被认为是存在病症并且或者受伤.
