Too much or not enough niacin?

[Miss Lydia]

I have no idea if they do or not. I have always used liquid B complex and Nutritional yeast. Might be that is something we need to look into. I'm all for natural sources.

Their feed is an 18% starter.

Consider switching to Purina flock raiser.. no need to supplement niacin unless raising jumbo Pekin. I contacted the company and verified it to be at 55mg/kg.

18% protein for the first 2 weeks is 4% LESS than desirable. according the following trusted resource link. which states..

* If you cannot find a starter feed with at least 22% protein, then you can use a 20+% protein starter feed but you must use it for at least four weeks.

Contrary to popular belief, angel wing is NOT *likely* caused by protein but by excess calories from ANY source very likely coupled with genetic predisposition as far as I can tell.


"Brewer's yeast human grade and livestock grade. Human grade has 5 mg of niacin per 15 grams of yeast (one tablespoon). Livestock grade has 1.5 mg per 15 grams of yeast."

Taken from this link that describes supplementation amounts and differences quite well..

That's good information, thank you! I haven't looked into the flock raiser because it's important to me that the feed is non-gmo, but I do have a local co op who can get organic feed specific for ducks and 22% starter. Cost is a bit high but I might be able to do it during breeding season because of extra funds from selling ducklings. I raised 3 ducklings on it some weeks ago and had no issues with angel wing.
