Bunnies might consume pieces of their own teeth when they munch on food– implying each mouthful might consist of a healthy dosage of calcium, researchers state.
Rabbits need big quantities of calcium, due to the fact that their teeth– like those of squirrels, beavers and kangaroos– grow continually. Previously, scientists presumed that wild bunnies intentionally consumed calcium-rich foods, such as leafy greens, to sustain this development. A brand-new research study reveals this might not be needed for bunnies to satisfy their mineral requires.
A naturally high-fiber diet plan suggests bunnies are continuously chewing and grinding their teeth. The resulting tooth powder might offer a consistent source of calcium that gets reabsorbed throughout food digestion, forming a cool loop that constantly fuels bunny tooth development, according to the research study.
“It has been suggested that rabbits must have high mineral requirements, in particular for calcium,” scientists composed in the research study, released in the February concern of The Veterinary Journal “However, this assumption ignores the fact that tooth wear represents finely ground tissue that is not lost to the body but swallowed during food processing.”

To evaluate whether tooth wear might be a source of calcium for bunnies, the scientists carried out a two-week feeding experiment on 8 female European bunnies (Oryctolagus cuniculus. They provided the bunnies food pellets consisting of either a basic calcium supplement or ground-up bunny teeth, and after that determined absorption in the body by examining the bunnies’ poop.
The outcomes revealed that bunnies can absorb and soak up calcium from their own teeth. They are most likely to draw out a little more calcium from their teeth than from food, according to the research study.

Poop samples showed the bunnies that got the tooth-powder diet plan absorbed 33% of the calcium they consumed, compared to 20% for the bunnies that got the basic supplement. There was no considerable distinction in the typical water consumption, body mass or fecal output in between the 2 groups, the scientists kept in mind.
Pet-rabbit feed usually includes calcium to offset the reality that family pets can’t separately choose foods high in calcium. The brand-new findings recommend we might be providing pet bunnies too much calcium, the scientists composed.

Healthy bunnies can excrete excess calcium in their urine, however bunnies with kidney issues might establish issues from excess calcium. Urinary system illness prevail in family pet bunnies, so it’s essential to watch on their mineral consumption, according to the research study.
It’s extremely most likely that bunnies swallow their own ground-up teeth, the research study does not reveal this straight. The scientists did not determine missing teeth throughout the experiment, indicating they did not represent the extra calcium that rabbits from both groups might have consumed. It’s likewise uncertain just how much calcium bunnies need to sustain constant tooth development.
The brand-new research study is a great beginning point, as it shows for the very first time that rabbits can absorb calcium from their own teeth.
“It’s an interesting puzzle piece about a great invention of nature,” research study co-author Dr. Jean-Michel Hatta teacher of veterinary medication at the University of Zurich, informed New Scientist “We will certainly continue the study of the abrasion and regrowth of teeth.”
