摘要

本研究目的在探討豬隻於屠宰場之繫留欄內利用各種趕豬方式，包括手趕（A組）、木棒（B組）、木板（C組）及電擊棒（D組），將豬隻自繫留欄驅趕至電昏室加以電昏及屠宰，計算豬隻移動效率及分析屠體性狀。試驗結果顯示豬群使用電擊棒驅趕的移動效率顯著高於其他三組方式（P＜0.05）。各處理組屠體於0℃預冷室冷卻24小時後，發現電擊棒組的屠體中心溫度降低速度慢（P＜0.05）且背最長肌的電導度值顯著高於其他三組方式（P＜0.05）。分切肉質性狀表現以電擊棒組蒸煮失重率顯著高於木板組（P＜0.05）。截切值則是電擊棒組低於木板組（P＜0.05）。肉中游離水含量以電擊棒組顯著高於其他三組方式（P＜0.05）。綜合各項試驗的結果顯示，豬隻屠宰前使用電擊棒電擊驅趕非僅為害屠肉品質且有虐待豬隻違反動物褔利觀念的落實。

The experiment was conducted to investigate the effects of applying different driving methods (including driving pigs by hand, by wood stick, by wood board and by electric goad) on moving efficiency and carcass quality in hybrid pigs. Each pen held 25 pigs. Before slaughter, pigs were driven by different driving methods from the holding pen to stunning room. The distance between the holding pen and stunning room was 25 meters. After slaughter, the carcasses were held in chilling room (0℃) for 24 hours and then were sampled for measuring the carcass characteristics. The results showed that moving efficiency by using electric goad was the best among the treatments (P ＜0.01). And the driving with electric goad resulted in significantly higher electrical conductivity, L value, cooking loss and free water content on the pig carcass than those using wood stick (P ＜0.05). In conclusion, pigs driven by electric goad not only harmed the carcass quality, but also violated the animal welfare concept.
