We fortify each of these products with considerably more than enough to meet the niacin requirements of each of the relevant species. Layer chicks need a minimum of 27 ppm for the first six weeks of life, less after that. Ducklings need 55 ppm, and gamebirds need 30 to 70 ppm, depending on the specie. Purina products are optimally fortified to meet the needs of these various types of birds.
Hope this helps - Let me know if you have other questions!
@DrPatrickBiggsLooking to buy a product with 70 ppm. Does Purina make one?
