Abstract

Wearable and implantable physiological monitors are designed for minimally invasive health assessment in companion animals. We aimed to establish proof-of-concept for the use of PetPace collar monitors and VetChip implantable monitoring devices in pigs. PetPace monitors were used to measure pulse rate, respiratory rate and heart rate variability in individually housed pigs. Group housed pigs were fitted with PetPace monitors to assess their feasibility for use in the presence of conspecifics, in addition to implantation with VetChip subcutaneous monitoring devices. PetPace monitors caused skin abrasion after 10 days of continual wear, but simple modifications allowed collars to be worn safely in individually housed pigs. Collars could not be worn unsupervised by group housed pigs due to damage by conspecifics. PetPace pulse and respiratory rate readouts showed a strong correlation with manual auscultations, and PetPace heart rate variability showed a very strong negative correlation with salivary corticosterone levels. VetChip temperature and pulse rate readouts were accurate in healthy pigs. However, the suitability of dorsal mid-scapula VetChip implantation is questionable due to wound breakdown in two out of three pigs.

微创生理监测技术在猪科研中的应用。

可穿戴和植入式生理监测仪设计用于伴侣动物的微创健康评估。我们的目标是建立PetPace项圈监测器和VetChip植入式监控设备在猪身上的概念验证。PetPace监测器用于测量单独饲养的猪的脉搏率、呼吸率和心率变异性。除了植入VetChip皮下监测装置外，还为组猪安装了PetPace监测器，以评估其在同种异体存在时使用的可行性。PetPace监测器连续佩戴10天后会造成皮肤磨损，但简单的修改可以让单独饲养的猪安全地佩戴项圈。项圈不能佩戴无监督的群体饲养猪由于损害同种。PetPace脉搏和呼吸频率读数显示与人工听诊有很强的相关性，PetPace心率变异性显示与唾液皮质酮水平有很强的负相关。VetChip在健康猪身上的温度和脉搏率读数准确。然而，由于三分之二的猪的伤口破裂，背侧肩胛骨中部植入VetChip的适用性值得怀疑。

期刊介绍： Journal of Applied Animal Welfare Science (JAAWS) publishes articles on methods of experimentation, husbandry, and care that demonstrably enhance the welfare of nonhuman animals in various settings. For administrative purposes, manuscripts are categorized into the following four content areas: welfare issues arising in laboratory, farm, companion animal, and wildlife/zoo settings. Manuscripts of up to 7,000 words are accepted that present new empirical data or a reevaluation of available data, conceptual or theoretical analysis, or demonstrations relating to some issue of animal welfare science. JAAWS also publishes brief research reports of up to 3,500 words that consist of (1) pilot studies, (2) descriptions of innovative practices, (3) studies of interest to a particular region, or (4) studies done by scholars who are new to the field or new to academic publishing. In addition, JAAWS publishes book reviews and literature reviews by invitation only.
