Means, sample sizes, and 95% confidence intervals for within-individual chewing-parameter ratiosa.
| Comparison | Chewing frequency (chews/s) | Chewing duration (s) | Chewing investment (chews/g) |
|---|---|---|---|
| Hay/carrots | 0.96 (n = 4, 0.84–1.11) | 9.02 (n = 4, 7.10–10.81) | 8.53 (n = 4, 7.47–9.67) |
| Hay/pellets | 0.99 (n = 12, 0.97–1.01) | 3.22 (n = 14, 2.79–3.68) | 2.95 (n = 12, 2.58–3.35) |
| Pellets/carrots | 1.06 (n = 13, 1.00–1.10) | 2.20 (n = 13, 1.93–2.52) | 2.32 (n = 13, 2.01–2.61) |
Notes.
Due to small sample sizes, confidence limits were not generated for hay-carrot comparisons; in this instance, the range of values is presented.
