In two cattle head deboning plants, a total of 8879 cattle skulls were investigated for number and precision of shots. Deviation from the ideal position on the forehead and the direction of the shot were measured, results were then attributed to three classes of precision. In all, 64.7% of the skulls in plant 1 and 65.3% in plant 2 were shot from the ideal position and in the ideal direction. A medium precision was observed in 31.3% and 31.5% of cases, 4.0% and 3.1%, respectively, of the skulls indicated a poor precision. In both plants, skulls with more than one shot hole were observed. Shot holes may indicate the precision of a shot, and thus the risk of suffering during the sensitive time of stunning. In addition to observations at the time of stunning, the observation of shot holes on skulls at random or in total after a day's slaughter can reflect the shooting precision.
在两家牛肉屠宰场中，总共检查了 8879 头牛的头骨，以确定击打的数量和精度。测量了额头偏离理想位置和射击方向的偏差，然后将结果分为三个精度等级。在工厂 1 中，64.7%的头骨和工厂 2 中 65.3%的头骨是从理想位置和理想方向射击的。31.3%和 31.5%的头骨属于中等精度，分别有 4.0%和 3.1%的头骨精度较差。在这两个工厂中，都观察到了有多个弹孔的头骨。弹孔可以指示射击的精度，从而反映出在敏感的击晕时间内动物的痛苦程度。除了在击晕时进行观察外，在一天的屠宰后随机或全部观察头骨上的弹孔，也可以反映出射击的精度。
