Protein model equations for total fecal bile acids excretion.
| Species | Soluble fibera | Outcomeb | Equation |
|---|---|---|---|
| Dog | No | Fecal excretion of BA (lognormal distribution) | = -0.954 (± 0.2888) – 0.454 (± 0.2997) + 0.014 (± 0.0177) × Dietary protein (%) |
| Yes | = -0.954 (± 0.2888) – 0.454 (± 0.2997) + 0.032 (± 0.0190) × Dietary protein (%) | ||
| Guinea Pig | No | = -0.954 (± 0.2888) – 0.821 (± 0.3030) + 0.014 (± 0.0177) × Dietary protein (%) | |
| Yes | = -0.954 (± 0.2888) – 0.821 (± 0.3030) + 0.032 (± 0.0190) × Dietary protein (%) | ||
| Hamster | No | = -0.954 (± 0.2888) – 0.974 (± 0.1923) + 0.014 (± 0.0177) × Dietary protein (%) | |
| Yes | = -0.954 (± 0.2888) – 0.974 (± 0.1923) + 0.032 (± 0.0190) × Dietary protein (%) | ||
| Rat | No | = -0.954 (± 0.2888) + 0.014 (± 0.0177) × Dietary protein (%) | |
| Yes | = -0.954 (± 0.2888) + 0.032 (± 0.0190) × Dietary protein (%) |
a
Addition of an ingredient in the diet that is a major source of soluble fiber.
b
Fecal excretion of BA must be backtransformed from a lognormal distribution to obtain results in μmol/g food intake.
