Application of electrocutaneous stimuli for short-time excitation of swine, accompanied by high locomotor activity, led in animals weighing between 30 kg and 45 kg to steep rises of catecholamine and glucocorticosteroid plasma concentrations, while little change was recordable from protein-linked iodine. Increase in plasma glucose and RQ in animals with higher rises in plasma-borne catecholamines and glucocorticoids was higher than that in animals with lower catecholamine deflection. Both the results reported in this paper and findings obtained from other studies into swine are likely to suggest major involvement of the sympathico-adrenomedullary system in the buildup of transport stress. Interdependence was found to exist between the intensity of the adrenergic reaction, on the one hand, and rises in plasma glucose and RQ as well as drop of pH, on the other. Those findings from various tests seem to support the conclusion that under conditions of severe excitation and high locomotor activity the differentiated resistance of swine to stress is atributable to different intensities of sympathico-adrenergic reaction of the animal concerned.
对体重在30公斤至45公斤之间的猪施加电皮肤刺激以进行短时间激发，同时伴有高运动活性，导致血浆中儿茶酚胺和糖皮质激素浓度急剧上升，而蛋白结合碘几乎没有变化。血浆中儿茶酚胺和糖皮质激素升高幅度较大的动物，其血浆葡萄糖和呼吸商的增加高于儿茶酚胺变化较小的动物。本文报道的结果以及其他对猪的研究结果都可能表明，交感 - 肾上腺髓质系统在运输应激的形成中起主要作用。研究发现，一方面肾上腺素能反应的强度与另一方面血浆葡萄糖和呼吸商的升高以及pH值的下降之间存在相互依赖关系。各种测试的这些结果似乎支持这样的结论：在严重激发和高运动活性的条件下，猪对压力的不同抵抗力归因于相关动物交感 - 肾上腺素能反应的不同强度。
