猪痛觉的行为学评价研究进展

Research Progress of Behavioral Evaluation on Pig Pain

随着对动物福利问题的关注和重视,如何在养殖和管理过程中减少猪的疼痛感受是畜牧兽医工作者面临的新课题。在猪肉生产过程中,特别是在养殖环节猪会经历一系列管理程序(例如剪牙、阉割、断尾等)、打斗受伤、环境因素造成跛行以及其他疾病引起的疼痛。结合养猪管理实践对猪疼痛发生、疼痛评估、行为学变化以及定量感官测试等方面进行阐述,总结了评估猪疼痛的方法和行为学指标。由于目前动物的疼痛评价在猪上没有统一的标准和方法,因此总结国内外猪痛觉的行为学相关研究进展,能为开发更多有效缓解疼痛的药物及制定有关策略提供参考。

With the attention to animal welfare issues, how to reduce the pain of pigs in the process of breeding and management is a new topic facing to livestock veterinarians. In the process of pork production , pigs will undergo a series of management procedures (such as tooth cutting, castration and tail-cutting, etc.), fighting injuries, lameness caused by environmental factors and pain caused by other diseases. With the combination of pig management practices, this paper explained the pain occurrence , pain assessment, behavioral changes and quantitative sensory tests in pigs, and summarized the methods and behavioral indicators for the evaluation on pig pain. Since there was no unified standard and method for animal pain assessment in pigs, this article summarized methods and behavioral indicators for assessing pig pain so as to provide references for the development of more effective pain relief drugs and the preparation of relevant strategies.
