rice hulls
Rice hulls are the husk the mill removed — abrasive silica-rich fiber at the rough end of the inert-bulk tier, and a rice word in the tally.
What it is
The hard protective husks of rice grains: heavily silicified, essentially unfermentable, the roughest of the inert fibers. Feed use is legitimate but low-grade — hulls are bulk, full stop.
Why it's in pet food
Cost-driven fiber where cheaper is the operative word. The peanut-hulls reputation logic applies: identical FUNCTION to refined cellulose, rougher pedigree, and premium labels avoid the word.
How Bowlmark scores it
Scores are deterministic math over the printed label — the rules below apply to every product identically, and nothing estimates or fills in a blank.
A rice word for the splitting base and otherwise unrated — the engine prices inert fiber at zero under every name. Reading advice: hulls prominent on a label is a value-tier tell the way 'powdered cellulose' in a diet food isn't; context, as ever, is the actual signal.
