Beet pulp and taurine status in dogs on low-protein diets

Taurine concentrations declined in all groups and were lowest with beet pulp. Protein digestibility was lower and bile acid excretion higher in that group.

DogFeeding or challenge experiment

Review scope

Abstract-based review. Full methods, complete statistical results and product equivalence have not been appraised. This is research context, not an individual feeding or treatment recommendation.

Study question and design

Medium and large mixed-breed dogs. Low-protein purified diets with beet pulp, cellulose or rice bran for 12 weeks.

Main findings

Taurine concentrations declined in all groups and were lowest with beet pulp. Protein digestibility was lower and bile acid excretion higher in that group.

Limitations and applicability

This formulation-specific experiment did not measure clinical heart disease. One beet-pulp dog was withdrawn after excessive weight loss.

Ingredients investigated

Direct ingredient investigations

Beet pulp

Direct · dog. 18 medium-to-large mixed-breed dogs fed low-protein purified diets.

Tested form: Dietary beet pulp in a low-protein purified diet. Dose: Not reported in reviewed abstract (Fibre source incorporated in the diet; inclusion level not reported in the reviewed abstract). Duration: 12 weeks; one beet-pulp-fed dog withdrawn at 10 weeks after excessive weight loss. Comparator: Low-protein purified diets using cellulose or rice bran as alternative fibre sources.

Measured finding: Taurine concentrations fell in all diet groups. Beet-pulp-fed dogs had lower plasma and whole-blood taurine and lower protein digestibility than the cellulose and rice-bran groups, with greater faecal bile-acid excretion.

Limitations: Small groups and deliberately low-protein purified diets; one withdrawal. Taurine and digestion findings cannot be generalized to all commercial diets or used as a clinical heart-disease outcome.

Cellulose

Direct · dog. 18 medium-to-large mixed-breed dogs fed low-protein purified diets.

Tested form: Dietary cellulose in a low-protein purified diet. Dose: Not reported in reviewed abstract (Fibre source incorporated in the diet; inclusion level not reported in the reviewed abstract). Duration: 12 weeks; one beet-pulp-fed dog withdrawn at 10 weeks after excessive weight loss. Comparator: Other experimental low-protein fibre diets containing beet pulp and rice bran.

Measured finding: Taurine concentrations fell in all diet groups. Beet-pulp-fed dogs had lower plasma and whole-blood taurine and lower protein digestibility than the cellulose and rice-bran groups, with greater faecal bile-acid excretion.

Limitations: Small groups and deliberately low-protein purified diets; one withdrawal. Taurine and digestion findings cannot be generalized to all commercial diets or used as a clinical heart-disease outcome.

Rice bran

Direct · dog. 18 medium-to-large mixed-breed dogs fed low-protein purified diets.

Tested form: Dietary rice bran in a low-protein purified diet. Dose: Not reported in reviewed abstract (Fibre source incorporated in the diet; inclusion level not reported in the reviewed abstract). Duration: 12 weeks; one beet-pulp-fed dog withdrawn at 10 weeks after excessive weight loss. Comparator: Other experimental low-protein fibre diets containing beet pulp and cellulose.

Measured finding: Taurine concentrations fell in all diet groups. Beet-pulp-fed dogs had lower plasma and whole-blood taurine and lower protein digestibility than the cellulose and rice-bran groups, with greater faecal bile-acid excretion.

Limitations: Small groups and deliberately low-protein purified diets; one withdrawal. Taurine and digestion findings cannot be generalized to all commercial diets or used as a clinical heart-disease outcome.
