A research team led by Jackson Laboratory (JAX) Associate Professor Vivek Kumar, Ph.D., has developed a non-intrusive method to accurately and continuously measure mouse body mass using computer vision. The approach aims to reduce the stress associated with traditional weighing techniques, improving the quality and reproducibility of biomedical research involving mice.
I wouldn’t expect it to be consistent without their saying something about it. It seems difficult. Why not just put a scale in the mouse cage, with a food pellet on it? Mouse climbs onto the scale and you take a reading.
