Onverteerbare dierlijke vezels in rauwe vleesvoeding positief effect op darmgezondheid

Animal fibre: The forgotten nutrient in strict carnivores? First insights in the cheetah

In dit onderzoek werd gekeken naar het effect in van onverteerbare dierlijke producten in rauwe vleesvoeding, op de darmgezondheid van cheeta’s. Dit werd onderzocht door cheeta’s twee soorten voeding te voeren:

1. Complete konijnen
2. Rundvlees met een premix

Resultaten
“Feeding whole rabbit decreased faecal propionic (p < 0.001) and butyric (p = 0.013) acid concentrations, yet total SCFA was unaltered (p = 0.146). Also, a remarkably higher acetic acid to propionic acid ratio (p = 0.013) was present when fed whole rabbit. Total BCFA (p = 0.011) and putrefactive indole (p = 0.004) and phenol (p = 0.002) were lower when fed whole rabbit. Additionally, serum indoxyl sulphate, a toxic metabolite of indole, was analysed and showed a quadratic decrease (p = 0.050) when fed whole rabbit.”

Conclusie van de onderzoekers
Onverteerbare dierlijke vezels in rauwe voeding hebben positief effect op de darmen.

“Short-chain fatty acids (SCFAs), the end products of fermentation of dietary fibers by the anaerobic intestinal microbiota, have been shown to exert multiple beneficial effects on mammalian energy metabolism.”
