3115 end-of-lay battery hens and carcases were sampled at set points in the sequence of events that occurred between depopulation of the battery cages at the layer farms and the end of the evisceration line in two processing plants. Live birds were killed in a convulsion-free manner and carcases were dissected to determine the incidence of broken bones. 2. Of the live battery birds 29% had broken bones by the time they reached the waterbath stunner, with on average 0.5 broken bones per bird. Removing birds from the battery cages and hanging them on the slaughter line were identified as causes of broken bones. 3. By the time birds left the end of the eviscerating line, 98% of carcases had broken bones, with on average 6 broken bones each. The stunning, plucking and eviscerating processes caused most of this damage. In particular, stunning broke the furculum, coracoid and scapula, plucking broke the ischium, pubis and ribs, and evisceration damaged the ischium and pubis.

在两个加工厂中，从蛋鸡养殖场的鸡笼清栏到去内脏生产线结束这一系列事件的特定时间点，对3115只产蛋后期的蛋鸡及其 carcasses 进行了采样。活禽以无抽搐的方式宰杀，对 carcasses 进行解剖以确定骨折的发生率。2. 到达水浴式致昏器时，29%的笼养蛋鸡出现骨折，平均每只鸡有0.5处骨折。将鸡从鸡笼中取出并挂在屠宰线上被确定为骨折的原因。3. 当鸡离开去内脏生产线末端时，98%的 carcasses 出现骨折，平均每只 carcass 有6处骨折。致昏、拔毛和去内脏过程造成了大部分此类损伤。特别是，致昏会导致叉骨、喙突和肩胛骨骨折，拔毛会导致坐骨、耻骨和肋骨骨折，而去内脏会损伤坐骨和耻骨。
