Studies of the stress response in swine require repeated blood sampling to determine diurnal variations of measured parameters. Most of these methods require elaborate artificial habitats such as metabolism crates and/or physical restraint for venipuncture. In either case, the aversive nature of the sampling procedure induces activation of the hypothalamic-hypophyseal-adrenal cortical axis. The development of a nonaversive procedure for repeated blood sampling of swine is described in this paper. The pigs were unrestrained and maintained in groups in a variety of habitats.
对猪应激反应的研究需要反复采血以确定所测参数的昼夜变化。这些方法大多需要精心设计的人工饲养环境，如代谢笼和/或静脉穿刺时的身体束缚。在任何一种情况下，采样过程的厌恶性质都会诱导下丘脑 - 垂体 - 肾上腺皮质轴的激活。本文描述了一种用于猪反复采血的无厌恶程序的开发。猪未受束缚，成群饲养在各种环境中。
