Folate is essential for cell division and DNA synthesis, making it particularly critical during periods of rapid growth and reproduction. For pregnant does, adequate folate supports healthy fetal development and helps prevent birth defects in kits. Folate also supports red blood cell production and overall immune function. Like other B vitamins, rabbits obtain folate from both cecotropes and dietary sources — dark leafy greens are among the richest plant sources of folate, which is one more reason a generous daily salad benefits your rabbit's health.
A few leaves of romaine lettuce (about 40g) provide roughly 50mcg of folate — think of it as a tiny pinch of powder if you could see it in pure form. Your adult rabbit needs approximately 0.5 to 1.0mg of folate per kilogram of diet. Pregnant and nursing does may benefit from slightly higher intake, which a generous portion of dark leafy greens supports naturally.
0.0% of daily nutrient intake
Vitamin B9 (Folate) makes up 0.0% of your domestic rabbit's total daily nutritional requirements by weight. That's a tiny amount — but it matters.
Anemia (pale inner ears and gums), poor growth in young rabbits, reduced litter size and birth defects in breeding does, weakness, and increased susceptibility to infections. Deficiency is rare on a varied diet with normal cecotrophy.
Folate is water-soluble and excess is excreted readily. Toxicity from food sources is not a concern for rabbits.
| Life Stage | Size | Min | Max | Unit | Notes |
|---|---|---|---|---|---|
| Adult | — | 0.05 | 0.1 | mg | Per kilogram of diet. Dark leafy greens and cecotropes provide adequate folate. |
| Pregnant / Nursing | — | 0.1 | 0.2 | mg | Increased folate needs during pregnancy for proper fetal cell division and development. |
