Morphometric data that provide information on body conditions can be used to monitor the health and well-being of animals. In laboratory animals, they can help to evaluate the stress due to experiments or treatments, following the 3R principles. The aim of the present study was to obtain morphometric data of male and female African clawed frogs, Xenopus laevis, as the bases for body condition evaluations. Adult frogs (n = 198) were weighed and standardized photographs were taken. The photographs were used to determine several measurements (length, cranial width, caudal width, thigh width). In addition, a triangle was drawn to outline each frog’s simplified body form, and the triangle surface was calculated. In conclusion, the triangle surface drawn on the dorsal plane of each frog correlated with the body weight of the females. There were significant differences between the body weights and sizes of male and female frogs, with males being smaller (p < 0.001). Based on the morphometric data, females could be assigned to five groups in which an assessment of the animal’s well-being is feasible.
提供身体状况信息的形态测量数据可用于监测动物的健康和福利。在实验动物中，这些数据有助于遵循3R原则评估实验或治疗引起的应激。本研究的目的是获取非洲爪蟾（Xenopus laevis）雌雄两性的形态测量数据，作为身体状况评估的基础。对成年蛙（n = 198）进行称重并拍摄标准化照片。利用这些照片确定了几项测量值（体长、头宽、尾宽、大腿宽）。此外，绘制一个三角形来勾勒每只青蛙简化的身体形态，并计算三角形面积。总之，绘制在每只青蛙背平面上的三角形面积与雌性青蛙的体重相关。雌雄青蛙的体重和大小存在显著差异，雄性较小（p < 0.001）。基于形态测量数据，雌性青蛙可分为五组，在这些组中对动物的福利进行评估是可行的。
