Abstract

This study investigated the combined effects of transport distance and season on poultry mortality rates (end-of-lay hens, broiler chickens, turkeys, and ducks) during transport to slaughterhouses. Retrospective data analysis included all poultry shipments from Czech farms to Czech slaughterhouses from 2017 to 2023. In total, 11,503,789 end-of-lay hens, 807,874,546 broiler chickens, 1,075,070 turkeys, and 28,012,184 ducks were transported in the monitored period. The highest mortality rates were observed in laying hens (1.212 %) and broiler chickens (0.884 %) during winter when transported over very long distances (301 km and more). For ducks, peak mortality (0.589 %) was found during summer transport over the distances of 201-300 km (no ducks were transported for longer distances). In turkeys, the highest mortality (0.598 %) was recorded in autumn over distances of 51-100 km, likely due to the limited number of birds transported over longer distances (97 % of turkeys transported within 100 km) and during extreme-temperature seasons. These findings highlight the need for species-specific transport management strategies, particularly for vulnerable categories such as end-of-lay hens and broiler chickens.

摘要

本研究调查了运输距离和季节对家禽(产蛋末期母鸡、肉鸡、火鸡和鸭子)运输至屠宰场期间死亡率的综合影响。回顾性数据分析涵盖了2017年至2023年从捷克农场运往捷克屠宰场的所有家禽运输情况。在监测期内,总共运输了11,503,789只产蛋末期母鸡、807,874,546只肉鸡、1,075,070只火鸡和28,012,184只鸭子。产蛋末期母鸡(1.212%)和肉鸡(0.884%)在冬季长途运输(301公里及以上)时死亡率最高。对于鸭子,在夏季运输201 - 300公里时死亡率达到峰值(0.589%)(没有鸭子运输距离更长)。在火鸡中,秋季运输51 - 100公里时死亡率最高(0.598%),这可能是由于长途运输的火鸡数量有限(97%的火鸡运输距离在100公里以内)以及处于极端温度季节。这些发现凸显了针对特定物种制定运输管理策略的必要性,特别是针对产蛋末期母鸡和肉鸡等易受影响的类别。
