Norway大鼠褐家鼠（Rattus norvegicus）是全球最重要的脊椎动物害虫之一，因为它们对人类和动物健康的影响。有法律的和道德义务，以尽量减少野生动物管理对动物福利的影响，然而，在英国使用的捕鼠和饵诱方法的相对福利影响方面的数据很少，无法为管理决策提供信息。使用福利评估模型评估六种致命鼠管理方法的相对福利影响。15个利益相关者，包括野生动物管理、啮齿动物管理、啮齿动物生物学、动物福利科学、兽医科学和医学方面的专家参加了研究。最大的福利影响与三种诱饵方法有关，即抗凝剂、胆钙化醇和无毒纤维素诱饵（严重到极端的影响，持续数天），并在胶水捕集器上捕获（极端数小时）与脑震荡致死（轻度至中度数秒至数分钟）;从福利的角度来看，这些方法应被视为最后手段。较低的影响与笼子诱捕（中度至重度持续数小时）和震荡致死（中度持续数分钟）有关。应规范和测试捕捉陷阱，以确定那些导致快速昏迷;这种陷阱可能是最福利友好的选择评估杀死老鼠。我们的研究结果可以用来综合考虑大鼠福利与其他因素，包括成本，有效性，安全性，非目标动物福利和公众的可接受性时，选择管理方法。我们还强调了减少福利影响的方法以及需要更多数据的领域。
Norway rats (Rattus norvegicus) are considered one of the most significant vertebrate pests globally, because of their impacts on human and animal health.There are legal and moral obligations to minimise the impacts of wildlife management on animal welfare, yet there are few data on the relative welfare impacts of rat trapping and baiting methods used in the UK with which to inform management decisions.Two stakeholder workshops were facilitated to assess the relative welfare impacts of six lethal rat management methods using a welfare assessment model. Fifteen stakeholders including experts in wildlife management, rodent management, rodent biology, animal welfare science, and veterinary science and medicine, participated.The greatest welfare impacts were associated with three baiting methods, anticoagulants, cholecalciferol and non-toxic cellulose baits (severe to extreme impact for days), and with capture on a glue trap (extreme for hours) with concussive killing (mild to moderate for seconds to minutes); these methods should be considered last resorts from a welfare perspective. Lower impacts were associated with cage trapping (moderate to severe for hours) with concussive killing (moderate for minutes).The impact of snap trapping was highly variable (no impact to extreme for seconds to minutes). Snap traps should be regulated and tested to identify those that cause rapid unconsciousness; such traps might represent the most welfare-friendly option assessed for killing rats. Our results can be used to integrate consideration of rat welfare alongside other factors, including cost, efficacy, safety, non-target animal welfare and public acceptability when selecting management methods. We also highlight ways of reducing welfare impacts and areas where more data are needed.
