Abstract

The number of broilers recorded as dead on arrival (DOA) in 1113 journeys to a poultry processing plant was related to the length of the journeys. The average journey time was 3.3 h and the maximum recorded was 9 h. 2. Overall, 0.194% of 3.2 million birds were DOA. Mortality was higher for journeys which took longer. For journeys lasting less than 4 h the incidence of dead birds was 0.156%; for longer journeys the incidence was 0.283%. 3. There was some evidence that it was time of journey, rather than distance travelled, that was more important in determining mortality.

摘要

在前往一家家禽加工厂的1113次运输行程中，记录的抵达时已死亡（DOA）肉鸡数量与运输行程的时长有关。平均运输时间为3.3小时，记录的最长时间为9小时。2. 总体而言，在320万只家禽中，0.194%为抵达时已死亡。运输时间较长的行程中死亡率更高。运输时间少于4小时的行程中，死禽发生率为0.156%；较长行程的发生率为0.283%。3. 有证据表明，在决定死亡率方面，运输时间而非行驶距离更为重要。
