Everything I have researched and learned about this product is that it is going to be the best possible thing out there for my horse's pyloric ulcer prevention program, and so far, it is working. However, as he is an easy keeper and doesn't need much hard feed, it is difficult to mix a cup or more worth of powdered supplement with his hard feed and get him to eat it. He has started refusing his feed altogether because he doesn't like the excessive amount of powder, not even if we wet it down. I am going to try a different feed blend to see if we can keep him eating the ProtekGI powder, but I think it is going to cost me even more money to change his feed. On top of the very high cost of this supplement, I don't know if this feed change will be sustainable, and we may have to quit the supplement altogether and just forego the performance dreams we had, as I can't afford frequent ulcer scoping and treatment, which is just as expensive as this supplement is becoming. Wish there was a more affordable answer. Also wish this supplement could be provided in a palatable pellet form.
