Ultium is hard to come by here. There is only
one feed store that is "licensed" to carry it. I tried special ordering it
and found out that Purina dealers have to go to a "special training" to be
qualified to sell Ultium.
It reminds me of when Nutrena advertised the heck
out of Legacy, but none of the local feed stores carried it, and it was even a
little difficult to special order. And then they wondered why they didn't
have a market for it and discontinued it. Dumb.
There's an info number listed on the ultium.com website, maybe they could help
you. The ingredients and analysis are listed on the webpage, but
more info than that I think you'll have to contact Purina.
