Every day someone asks me about feeding their horses. For me it has become simple only because I have repeated this information but for you.... maybe not so simple. I review a lot of what I have said before and I use some different approaches to help you understand. It comes down to a few things: Protein, fat and sugar are the 3 main ingredients that enter the mouth (we won't worry about air, water and minerals here). These ingredients are broken down into fuels and building materials in the gut. The fuels and building materials are transported throughout the body to be either burned to make energy, stored for future use or used to make things. Nothing is wasted or goes wrong when the rules are followed. Humans break the rules all the time.
