Effects of environmental enrichment on males of a docile inbred strain of mice
Environmental enrichment is intended to improve the welfare of laboratory animals. However, regarding male mice, numerous studies indicate an increase in aggressive behavior due to cage structuring. On the one hand, this might be a problem concerning animal welfare. On the other hand, enrichment is though to hamper environmental standardization and to increase variability of […]
Effects of different forms of environmental enrichment on behavioral, endocrinological, and immunological parameters in male mice
This study investigated effects of different forms of environmental enrichment on behavioral, endocrinological, and immunological parameters in male mice. For this purpose, animals of the inbred strain CS were kept in groups of four males under three different housing conditions: (A) nonstructured Makrolon type III laboratory cages (“standard-housing” = S); (B) equivalent laboratory cages that […]
