The signs of niacin deficiency related to leg problems are enlarged hock joints and slipped tendons (called perosis) so the leg splays out. We do know that ducks have a higher requirement for niacin than chickens. NRC requirements for ducklings = 55 mg/kg niacin compared to only 27-35 mg/kg for chicks.On top of that, the niacin in corn has a very low bioavailability; although corn contains 24 mg/kg of niacin, I use a value of 2 mg/kg for formulation.ypically the pills contain 500 mgs of niacin per tablet. Assuming a duck is eating about .35 lbs per day (this is how much a Pekin is eating at about 3 -4 weeks of age) , they need 10 milligrams (mgs) of niacin a day. So, theoretically, one pill has enough niacin for 50 ducks.
