During the catching of broilers for slaughter, 2 to 3 birds are grabbed per hand at one leg at the same time. From an animal welfare point of view, this procedure is under critical observation from animal welfare administration and the general public.In this paper 2 catching methods were compared: the routinely used 1-leg catching method, and a second tech-nique whereby birds were grabbed by both legs with a maximum of 2 birds per hand (2-leg catching method). Lesions on the body, legs, and wings (hemorrhages and fractures) were recorded by a camera system located after the plucking position. Two weight classes, 2 catching teams, and 2 flocks were included in the study.Heavy animals showed more lesions than birds of the light weight class. In all investigations, lesions on the body and legs were rare, whereas wing lesions occurred at a rate of up to 15.32%. Statistical analysis showed no significant difference between the 2 methods or between the catching teams for both weight classes. A correlation between lesions and weight was observed, with a significant odds ratio ( OR: ) of 3.6 (95% CI: 3.299-3.957).During 2-leg catching, the animals appeared to be more restless. Workers stated that the grabbing of both legs of a bird was more difficult and that working in a crouching position for a longer time was harder.We conclude that the cautious handling of animals to reduce stress is more important than "holding animals by both legs", as has been proposed.
在抓肉鸡进行屠宰时，每只手同时抓住一只腿上的2至3只鸡。从动物福利的角度来看，这一过程受到动物福利管理部门和公众的密切关注。本文比较了两种抓鸡方法：常规使用的单腿抓鸡法，以及另一种技术，即每只手最多抓2只鸡的双腿抓鸡法（双腿抓鸡法）。通过位于拔毛位置之后的摄像系统记录鸡身体、腿部和翅膀上的损伤（出血和骨折）。研究纳入了两个体重等级、两个抓鸡小组和两个鸡群。较重的鸡比轻体重等级的鸡出现更多损伤。在所有调查中，身体和腿部的损伤很少见，而翅膀损伤发生率高达15.32%。统计分析表明，两种方法之间以及两个抓鸡小组在两个体重等级上均无显著差异。观察到损伤与体重之间存在相关性，显著优势比（OR：）为3.6（95%置信区间：3.299 - 3.957）。在双腿抓鸡过程中，鸡似乎更不安。工作人员表示，抓住鸡的双腿更困难，长时间蹲姿工作更辛苦。我们得出结论，如有人所提议的那样，谨慎处理动物以减轻压力比“抓住动物的双腿”更为重要。
