Abstract：
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 (n = 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 (p < 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 (p < 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.
摘要：
总的来说,2022年，德国约有6.31亿只肉鸡被屠宰。该评估包括大约的数据。2022年在德国运输的1.98亿只不同年龄和品种的肉鸡（占2022年所有肉鸡运输病例的31％）。这项研究的目的是分析2022年1月至2023年5月期间德国肉鸡运输（n=14,054）到屠宰场的死亡（DOA）率和可能的影响因素。因此,每次运输的动物总量之间的关系，运输的持续时间和距离，运输笼中的计划放养密度，统计评估了每日平均温度，一天中的时间和运输季节以及DOA率。结果显示平均DOA率为0.09%(SD0.09)。在中午(11:00至17:00)进行的运输显示出比在其他时间(一天分成6小时间隔)的运输更高的DOA率(p<0.05)。平均DOA率最高(0.10%)出现在秋季，接着是冬天,而春季和夏季的运输导致最低的DOA率（p<0.05）。总而言之，与其他欧洲国家的研究数据相比，德国相对较低的DOA率（％）表明其肉鸡运输的良好标准。
