Welfare[edit]
Since stress is highly correlated to carcass quality, reducing causes of stress during the slaughter process can drastically improve meat quality.[8] In addition, calmer animals will have a lower body temperature, which can help eliminate protein denaturation if no lairage time is allowed. In birds, improving environmental quality will help to eliminate wing flapping, vocalizations, and excessive movement as animals are transported from the farm into the abbatoir, which can reduce PSE incidence. Lower meat pH’s are correlated with the length and roughness of transportation.[6][7] Stress levels are also known to decline as human handling decreases.
As solutions, automatic loaders and unloaders may be useful for the poultry industry (although this topic is under debate due to high level of noise from those machines). Personnel training for humane catching by closing the wings, instead of grabbing birds by legs, is under review. It is thought that reduction of bruises, pain and fear (of humans or machinery) can have a positive effect on meat quality and welfare.[9] Following transportation and unloading, animals should be given an extensive rest period before stunning (referred to as lairage[8]) to allow animals to recover homeostasis, especially regarding lactic acid removal from tissues and glycogen reserves reestablishment. Stunning methods can play a large role in meat quality. Current research suggests that a two phase gas chamber may be best for minimizing stress.[3] During summer time or in hot countries, the truck design should be taken into consideration, and passive ventilation and water shower before leaving the farm can have a positive effect and reduce the occurrence of PSE by up to 66.3%, which can be done by costless modifications.[6]
