So asking the question: to feed commercial grain or not. There is proof about the specific damage caused by feeding grain to horses. I can tell you I have switched to a non-gmo feed such as CoolStance which is coconut meat which has been dried by the sun a few years back. But, just feeding forage with a good mineral like Equi-Pride nor another that you may like is really all they need. You will see the difference in their topline as well as hoofs, less issues as mentioned earlier in this article (no more leaky gut) and if you have a hot horse - they will be more relaxed. Less stressed - more pasture time is key if you are able vs. the stall. Stalled and competition horses have more issues. Overall - Healthier Horse!
