In total, around 631 million broilers were slaughtered in Germany in 2022. This evaluation included data of approx. 198 million broilers of different ages and breeds that were transported in Germany in 2022 (31% of all cases of broiler chicken transport in 2022). The aim of this study was to analyze German broiler chicken transport ( = 14,054) to the slaughterhouse between January 2022 and May 2023 with regard to the dead-on-arrival (DOA) rate and the possible influencing factors. Therefore, the relation between the total amount of animals per transport, the duration and distance of the transport, the planned stocking density in the transport cages, the average daily temperature and time of day and season of the transport as well as the DOA rate were statistically evaluated. The results showed a mean DOA rate of 0.09% (SD 0.09). Transport conducted at midday (11:00 to 17:00) showed higher DOA rates ( < 0.05) than transport at other times (day split into 6 h intervals). The highest mean DOA rate (0.10%) was found in the fall, followed by the winter, while transport in the spring and summer resulted in the lowest DOA rate ( < 0.05). All in all, the relatively low DOA rate (%) in Germany indicates the good standard of their broiler transport compared to available data from research in other European countries.
2022年，德国总计屠宰了约6.31亿只肉鸡。此次评估纳入了2022年在德国运输的约1.98亿只不同年龄和品种肉鸡的数据（占2022年所有肉鸡运输案例的31%）。本研究的目的是分析2022年1月至2023年5月间德国运往屠宰场的肉鸡运输情况（=14,054次），涉及到抵达时死亡（DOA）率及可能的影响因素。因此，对每次运输的动物总数、运输时长和距离、运输笼中的计划饲养密度、平均日气温、运输的时间以及运输季节与抵达时死亡率之间的关系进行了统计评估。结果显示，平均抵达时死亡率为0.09%（标准差0.09）。中午（11:00至17:00）进行的运输显示出比其他时间（一天分为6小时间隔）更高的抵达时死亡率（<0.05）。秋季的平均抵达时死亡率最高（0.10%），其次是冬季，而春季和夏季的运输导致最低的抵达时死亡率（<0.05）。总体而言，德国相对较低的抵达时死亡率（%）表明与其他欧洲国家的研究数据相比，其肉鸡运输标准良好。
