Tannins are polyphenolic compounds found in certain berries, bark, and some plants that bind to proteins and reduce their digestibility. In moderate amounts, tannins also have antioxidant properties and can help reduce intestinal parasites. For rabbits, tannin exposure from typical foods like berries and herbs is minimal and generally not a concern. Wild rabbits actually seek out tannin-containing plants as part of their natural self-medication behavior against gut parasites.
A few blueberries or raspberries (about 10g total, as an occasional treat) contain small amounts of tannins — well within safe levels. The tannin content in typical rabbit-safe foods is too low to cause any nutritional concern. No action needed beyond maintaining a varied diet.
0.07% of daily nutrient intake
Tannin Level makes up 0.07% of your domestic rabbit's total daily nutritional requirements by weight. That's a tiny amount — but it matters.
Not applicable — tannins are not a required nutrient.
Very high tannin intake can reduce protein absorption, cause constipation, and decrease feed palatability. This is unlikely from normal rabbit-appropriate foods but could theoretically occur if a rabbit consumed large amounts of certain astringent plants.
