Table 3.
Least square means and contrasts (FB0 vs. FB10–30 [T]; linear [L]; quadratic [Q]; cubic [C]) for food intake, fecal output, stool scores, and defecation frequency of dogs fed diets containing increasing levels of dehulled FB
| Parameter | FB0 | FB10 | FB20 | FB30 | SEM | FB0 vs. T | L | Q | C |
|---|---|---|---|---|---|---|---|---|---|
| Intake (DM), g/d | 147 | 148 | 152 | 147 | 6.1 | 0.735 | 0.847 | 0.631 | 0.732 |
| Fecal output (DM), g/d | 17.4 | 18.1 | 17.9 | 19.1 | 0.54 | 0.108 | 0.045 | 0.714 | 0.331 |
| Fecal output (as-is), g/d | 56.6 | 62.2 | 61.5 | 70.6 | 4.78 | 0.147 | 0.061 | 0.721 | 0.461 |
| Stool score1 | 3.77 | 3.65 | 3.72 | 3.53 | * | 0.031 | 0.006 | 0.469 | 0.051 |
| Defecation frequency, stools/d | 1.52 | 1.62 | 1.73 | 1.85 | 0.093 | 0.052 | 0.011 | 0.947 | 0.960 |
1Subjective 1 to 5 scale with 1, runny; 2, soft; 3, firm and moist; 4, firm; 5, dry and hard.
*SEM differed for each treatment due to unequal number of observations (SEM; 0.051, 0.049, 0.052, 0.043, for FB0, FB10, FB20, and FB30, respectively). Animal (P = 0.001) and diet (P = 0.007) had a significant effect on fecal scores, but there was no effect on the interaction.
