    Great for hard hauling

    Posted by Kirstin Carlson on Oct 5th 2021

    I took off this summer and hauled some horses to get some rodeo seasoning. 5,600 miles in 4 weeks and over a dozen rodeos. I used the performance dose of Gastro pHix on both horses. Both horses, including the super hot Dash Ta Fame 5yo, kept great appetites and never went off feed. They looked great and I even had to let the 5yo back cinch out during the trip. I feel confident that Gastro pHix helped my horses with the stress of hauling and prevented them from getting ulcers that is so common when seasoning young horses.

    I have only gotten a couple sample bags to see if my really picky gelding would eat it and he loves it he'll even eat it right out of hand and he normally won't even touch it especially any new supplement in his grain. I fed it right before loading him in trailer as he is a very hard hauler and before I ran him at a show seemed to help settle his tummy some hoping to try it full time in the spring to see how he really does on it for show season.

    Ulcery horse

    Posted by LB on Jul 10th 2021

    My horse was acting cinchy and being picky about Feed. She didn’t want to eat the Gastro pHix at first but after a few days she went to it and I immediately noticed changes in her behavior when I was tacking her up. I am excited to see how she does after using a full bag!

    I use the Succeed ulcer test. Some people like it others don't. My pony had a nice red line on hind gut ulcers. After a month on Gastro pHix he is now only a little pink for hind gut. So we will continue to use this and I will check him again in a couple of months.

    My horse took to this right away and although I think he has more of a hind gut issue, I may continue him on this especially after listening to the podcast with Dr. Jymie and Dr Bill. I especially appreciate that its in pellet form and can be given by itself or with his feed. Also appreciate the science behind it! Really appreciate the informative podcasts! thank you!!!
