Molybdenum serves as a cofactor for several enzymes involved in metabolizing sulfur-containing amino acids and breaking down purines. It is needed in extremely small amounts, and a normal diet of hay and greens provides more than enough for your rabbit's needs. Molybdenum deficiency has not been documented as a practical concern in domestic rabbits.
A small serving of peas (about 15g, as an occasional treat) provides trace amounts of molybdenum — there is no established specific requirement for rabbits, and the amounts naturally present in hay and vegetables are more than adequate.
0.0% of daily nutrient intake
Molybdenum makes up 0.0% of your domestic rabbit's total daily nutritional requirements by weight. That's a tiny amount — but it matters.
Not documented in domestic rabbits. Theoretical signs in other species include growth retardation and increased susceptibility to sulfite toxicity, but these are not relevant concerns for pet rabbits on a normal diet.
Very high molybdenum can interfere with copper metabolism in some species, but the amounts present in rabbit-appropriate foods are far below any concerning level.
