摘要
在科学研究中使用动物的研究人员必须在统计能力与满足 "三R "要求之间取得平衡。"三R "要求研究人员减少动物的数量,完善他们的经验,并尽可能使用替代品(取代)更多的动物。在对时间序列研究进行重复采样时,可能会出现功率损失,而且在无法管理或避免的情况下,对单个动物进行重复采样也会对伦理产生影响。在此,我们将从三个角度考虑重复取样的数学问题:整个种群的角度、个体经验的角度以及被取样个体再次被取样的条件概率。计算方法通过兽医流行病学中四个具有不同实际意义的理论案例研究和为研究人员提供的 R Shiny 工具进行了说明。尽管有精确的计算方法,但在取样研究中还必须考虑可能影响捕获率和再捕获率的生物因素,如动物的个性和对捕获的反应。研究人员还必须谨慎选择问题,以避免重复取样中出现不恰当的伦理问题。
The birthday problem: repeated sampling of animal populations and ethics of experimental design
Researchers who use animals in science must balance statistical power with the need to satisfy the three Rs, whereby researchers are required to reduce numbers of animals, refine what they experience, and use alternatives to (replace) higher animals where possible. In repeated sampling over time-series studies, there is potential loss of power as well as ethics implications posed by repeated sampling of individual animals, where this cannot be managed or avoided. Here, we consider the mathematics of repeated sampling from three perspectives: that of the population at large, from the experience of the individual, and the conditional probability of sampled individuals being sampled again. The calculations are illustrated using four theoretical case studies across veterinary epidemiology with different practical implications and a provided R Shiny tool for researchers. Despite the availability of exact calculations, it is necessary to also consider the biological factors which may affect capture and recapture rates in sampling studies such as animal personality and response to capture. Researchers must also choose their question carefully to avoid inappropriate framing of ethical concerns around repeated sampling.

Editorial board
animal attracts the best research in animal biology and animal systems from across the spectrum of the agricultural, biomedical, and environmental sciences. It is the central element in an exciting collaboration between the British Society of Animal Science (BSAS), Institut National de la Recherche Agronomique (INRA) and the European Federation of Animal Science (EAAP) and represents a merging of three scientific journals: Animal Science; Animal Research; Reproduction, Nutrition, Development. animal publishes original cutting-edge research, ''hot'' topics and horizon-scanning reviews on animal-related aspects of the life sciences at the molecular, cellular, organ, whole animal and production system levels. The main subject areas include: breeding and genetics; nutrition; physiology and functional biology of systems; behaviour, health and welfare; farming systems, environmental impact and climate change; product quality, human health and well-being. Animal models and papers dealing with the integration of research between these topics and their impact on the environment and people are particularly welcome.
