Sprouting only make the nutrients that is left after sprouting "more available".I believe you are incorrect, Chris09. It's my understanding that sprouting increases the bioavailability of the seed's nutrients.
Sprouting take a lot of nutrients and in doing so the product looses some nutritional value it would have as a seed, now it may gain some nutrients in the growth of vegetation and root but since chickens don't digest fibrous material very well there is a nutrient loss there.
What works for humans doesn't work for poultry and other livestock.
