Fecal corticosterone concentration in C57BL/6NHsd mice
| Mean fecal corticosterone (ng/g feces) | SE | P | |
| Cage density and sanitation frequency guidelines | |||
| Inhouse | 0.330 | 0.04a | 0.421a |
| Guide | 0.396 | ||
| Bedding type | |||
| Aspen | 0.397 | 0.04b | 0.752b |
| Cellulose | 0.321 | ||
| 50% aspen : 50% cellulose | 0.372 | ||
Fecal corticosterone was measured through collection of a single fecal pellet per cage on day 56 of the study.
a
SE and P value correspond to statistical analysis of inhouse and Guide treatments.
b
SE and P value correspond to statistical analysis of bedding treatments.
