Figure 2. The Burrowing test.

Figure 2

Mice on HF diet removed significantly less bedding material from the tube than mice on C diet (p = 0.035). A tendency of reduced burrow-digging is seen for mice on HS diet (p = 0.064). However, although not quantified, this diet group burrowed less goal-oriented, as observations showed excessive digging in the whole cage. Median with ranges.
