Actually it's not a shampoo. It's a Purina product designed for horses, but is basically the same as any energy pellet, high fat, low protein. I have never used the product but just thought i would clear that up
Yeah we handled it at the feed mill i worked at in college. sold quite a bit to horse people. i assume it would work similarly to any other energy supplement, but i think it is formulated for horses so check the label before you feed it to cattle
