Short-chain fructooligosaccharides (scFOS) and
galactooligosaccharides (GOS) are non-digestible oligosaccharides that result
in a prebiotic effect in some animal species; however, the cat has not been well
studied in this regard. This experiment evaluated scFOS and GOS supplementation
on nutrient digestibility, fermentative end-product production and fecal
microbial ecology of cats.
Eight healthy adult cats were fed diets containing no
prebiotic, 0.5% scFOS, 0.5% GOS or 0.5% scFOS + 0.5% GOS (scFOS + GOS).
Apparent total tract crude protein digestibility was decreased with the scFOS +
GOS diet compared to the other treatments.
Cats fed scFOS, GOS and scFOS + GOS supplemented diets had
greater fecal Bifidobacterium spp.
populations compared to cats fed the control diet. Fecal pH was lower for cats
fed the scFOS+GOS supplemented diet compared to the control. Butyrate and
valerate concentrations were higher when cats consumed the scFOS + GOS diet.
Acetate tended to be greater when cats were fed the scFOS + GOS diet, as did total
SCFA and total BCFA concentrations.
Low level supplementation of scFOS, GOS and their
combination exert positive effects on select indices of gut health in cats.

Tomato pomace has the potential to provide additional nutrition and health benefits
What is this quiet, unassuming ingredient, and should it be there?
5 small steps would streamline information on petfood ingredients to help communicate with pet owners
The question is whether they provide additional benefit to the dog or cat
It's an "Intel inside" type of molecule -- but also a problem child
It's the finishing touch that can meet both owner and pet needs.
