三组养殖的红鹿在田间被射杀，三组在农场被屠宰，三组被运送到商业屠宰场。观察动物的行为，屠宰后立即测量外周血浆皮质醇浓度，屠宰后24小时测量颈部肌肉pH值。当只有一个畅通无阻的方向对它们开放，环境中没有任何东西引起警报时，鹿可以被处理和放牧而不受干扰。浅角度的装载坡道更可取。鹿射击在外地和鹿围栏没有处理有较低的平均血浆皮质醇浓度（小于7 ng/ml）和肌肉pH值小于5.74，而鹿已被放牧在农场，或运输到屠宰场，有较高的皮质醇浓度（大于20 ng/ml）和肌肉pH值高于5.74。然而，只有四个66公鹿运送到屠宰场的肌肉pH值高于6.0，pH值与黑色切割肉在红鹿。
Three groups of farmed red deer were shot in the field, three groups were slaughtered on the farm and three groups were transported to commercial slaughterhouses. The behaviour of the animals was observed and peripheral plasma cortisol concentrations were measured immediately after slaughter and neck muscle pH was measured 24 hours after slaughter. The deer could be handled and herded without agitation when only one unhindered direction was open to them and nothing in the environment caused alarm. Shallow angled loading ramps were preferable. Deer shot in the field and deer penned without handling had low average plasma cortisol concentrations (less than 7 ng/ml) and a muscle pH less than 5.74 whereas deer which had been herded on the farm, or transported to a slaughterhouse, had high cortisol concentrations (greater than 20 ng/ml) and a muscle pH above 5.74. However, only four of 66 male deer transported to a slaughterhouse had a muscle pH above 6.0, the pH associated with dark cutting meat in red deer.
