| PTC concentration, mM | P values | ||||||||
|---|---|---|---|---|---|---|---|---|---|
| Variable | 0.20 | 0.43 | 0.94 | 2.03 | 4.39 | Pooled SE | Treatment | Sequence | Period |
| Total test fluid intake as a percentage of total offered (1.5 kg water and 1.5 kg PTC solution) | 67.3a | 58.9b | 64.3a,b | 61.3a,b | 50.8c | 4.5 | 0.0002 | 0.86 | 0.02 |

Treatment refers to PTC concentrations, sequence is the order PTC concentrations were administered to rams, and period is the day PTC was administered within the sequence.
a,bMeans with different superscripts within a variable and across PTC concentrations are different (P ≤ 0.05).
