Body weights among mice housed in a standard environment (SE) or an enriched environment (EE) during 6 weeks. (A) Actual weights increased over the course of the 6-week housing in both SE and EE mice, but EE mice weighed less than SE mice during Weeks 5 and 6. (B) Mice housed in EE gained as much weight as mice housed in SE at Weeks 1–4 but at Weeks 5 and 6, percentages of weight change from weaning were reduced in EE mice compared to SE mice. *p < 0.05 relative to mice housed in SE. Data represents means ± SEM (mice housed in SE, n = 33; mice housed in EE: n = 36).
