Stock management of the Swiss water buffalo livestock results in the slaughtering of about 350 animals per year. As the stunning of water buffaloes still is an unresolved issue, we investigated the terminal ballistics of currently used perforating stunning devices. Cartridge fired captive bolt devices, handguns and a bullet casing gun were tested in a shooting steep by firing on bisected heads, forehead plates and soap blocks. Energy loss of captive bolts confirmed their inadequacy when used for heavy water buffaloes, notably adult males. As for the free projectiles, ballistics revealed that beyond the impact energy, bullet deformation has a strong impact on the outcome. Light 9mm Luger or .38 Spl bullets as well as large deformable .44 Rem. Magnum bullets should be avoided in favor of heavier .357 Magnum deformation ammunition. These data have been translated into the development of a new stunning device for water buffaloes meeting both animal welfare and occupational safety requirements.
瑞士水牛奶牛的库存管理导致每年大约有 350 头动物被屠宰。由于水牛头的击晕仍然是一个未解决的问题，我们研究了目前使用的穿孔击晕设备的终端弹道学。在一个陡峭的射击坡度上，通过对半切开的头部、额板和肥皂块进行射击，测试了弹筒式击晕枪、手枪和弹壳枪。捕获螺栓的能量损失证实了它们在用于大水牛，特别是成年雄性时的不足。至于自由发射物，弹道学表明，除了冲击能之外，子弹变形对结果有很大的影响。应避免使用轻 9 毫米 Luger 或.38 Spl 子弹以及大变形的.44 Rem. Magnum 子弹，而应选择更重的.357 Magnum 变形弹药。这些数据已被转化为一种新的水牛头击晕设备的开发，该设备符合动物福利和职业安全要求。
