Stunning evolution

摘要

In beef plants, the performance of the captive-bolt stunner has been paramount to developing humane slaughter for more than 100 years. However, a 1996 survey by animal-handling expert Dr. Temple Gran-din, showed that only 36 percent of plants were able to achieve acceptable stunning scores, highlighting a serious need to improve. Equipment manufacturers were challenged to improve the tool with the goal of delivering "first-time, every-time" stunning.
