Pups were identified by toe clipping or tattooing the plantar surface of the paws on day 4 after delivery. Their growth, maturation, and reproductive capability were not affected by either identification method. In the toe clipping group, however, the duration until fall in the suspension test was significantly shortened, indicating that this identification method may not be suitable for some behavioural tests. The clipping also disturbs the skeletal investigation of toes and is not recommended from the view point of animal welfare. Palm tattooing, on the other hand, satisfies the fundamental requirements for long-term identification of rats.
幼崽在出生后第4天通过剪趾或在脚掌跖面纹身来进行标识。两种标识方法均未影响它们的生长、成熟和繁殖能力。然而，在剪趾组中，悬尾试验中出现坠落的时间显著缩短，这表明这种标识方法可能不适用于某些行为测试。剪趾还会干扰对脚趾的骨骼检查，从动物福利的角度来看不建议使用。另一方面，脚掌纹身满足了对大鼠进行长期标识的基本要求。
