Environmental enrichment does not disrupt standardisation of animal experiments

ALTEX. 2007:24 Spec No:70-3.


Environmental enrichment can prevent abnormal behaviours and improve the well-being of laboratory mice, but concerns have been raised that it might disrupt the standardisation of experiments. Based on a multi-laboratory study, I show that animal welfare can be improved by environmental enrichment without disrupting standardisation.
