I've only just started to really dig into the aspects of nutrition, having become madly frustrated by Cargill / Purina / DuMor ... seems they'd rather deprive our chickens of essential nutrients, and feed 'em all aflatoxins, rather than give up a few pennies on the pound.
Soy contains natural toxins known as
anti‐nutrients comprised of such factors as saponins, soyatoxin, phytates, protease inhibitors, oxalates, goitrogens and estrogens. This is not a health issue unless you are eating soy in large amounts each day.
Goitrogenic foods are already borderline in most feeds, which can be offset by iodine supplementation, but I'd look to increase thiamine (B1) and riboflavin (B2) in other ways. These seem to most often be an issue, as thiamine is blocked by medicated feeds, and thiaminase enzymes make it biologically unavailable. Riboflavin can be easily lost into water, and breaks down so quickly in light, that it's seriously difficult to get sufficient levels into livestock/poultry.
But, in efforts to increase these, I'm fearful of givin' far too much of other nutrients/vitamins ... so far? It looks like dairy products (esp. from w/in paper cartons) are helpful, and brewer's yeast, but by far and away: Marmite, a yeast extract spread, appears to be superior as a source.
