I looked at the tags, the ultimate has a higher vitamin E content. I may switch to that this time. I am using concept aid on a group of cows this spring to compare conception rates with the ones on the co-op mineral and the same cows preg rate last year. The vitaferm is about double the price, Will let you know how it turns out. If it increases the preg rate by 5-6% like everyone in their testimonials is claiming, it will pay for itself. My local co-op odered the vitaferm mineral for me, I'm sure they can do the same for you.
I'm curious what you pay for the Vitaferm Concept Aid Mag. We pay $32.00 I think. Feel it is worth the extra for the extra Mag.
