Effect of a partial cage dividing enrichment on aggression-associated parameters in group-housed male C57BL/6NCrl mice

Group-housing is highly important for social animals. Group-housing of male mice in captivity though often leads to aggression with partially disastrous consequences for the animals as well as for the quality of experimental data. In this study we investigated the effect of a novel “cross-enrichment”, i.e. a colored partial cage divider, which is provided in transparent or black and which is partly separating the cage in four small areas....
