Crossing the Road
Basic biology. Almost every ingredient commonly used in chicken feed is plant-based, and plants tend to have low levels of Methionine. Legumes like soy tend to have the closest ratio of AA to what a chicken needs - an animal's AA ratios tend to differ significantly from a plant - but when combining a mostly right, with a lot of low Met sources, end result is a low Met feed.I have to ask why this is. What sources of Methionine are feed companies using that can’t be found in organic food?
and that's before you further limit your sourcing to organic crops of X Y Z
/edit and animal proteins, which tend to have good AA levels including Met are often not included in Organic feeds, and since they are often byproducts (i.e. porcine blood meal, menhaden fish meal), organic sourcing of the supply chain can be difficult.
