Show abstract
Laboratory animals are raised in a fixed space during the study period and are environmentally bound. Laboratory animal may be under stress on the constrained environment, which changes physiological indicators, affecting the reproducibility and accuracy of animal study. Therefore, reducing animal stress by providing proper breeding environment and environmental enrichment can be the basis for animal study. In this study, the stress level was assessed according to the mouse breeding environment. According to the results of the experiment, it was determined that the individual ventilation cage had less cortisol concentration in serum and body weight increased in the individual ventilation cage than individual isolated cage, when providing environmental enrichment rather than group breeding or not providing environmental enrichment. The results will provide appropriate guidelines for laboratory animal welfare.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
