I equated this pre-grain hay to the tiny salad brought out by the waiter at a nice restaurant. Placed on a tiny plate and consisting of a few pieces of lettuce, a ring of onion, one cherry tomato and a few croutons. It was meant to bridge the gap between the time when your mother cut you off from the bread basket (after your third or fourth breadstick) until your meal arrived. It wasn’t the meal itself and to me had no impact on my daily intake (I didn’t even factor it in when deciding what to order).
I know now that I was wrong. Salads can make fine meal, wonderful meals in fact, where all of your nutritional requirements are met and you are left sated. For humans we should strive to make the components of a salad the bulk of our diets, I bet we would be a lot healthier as a population. In horses it is even more important than that. Hay is not a side salad intended to keep horses calm while waiting for the real meal, in fact it should be the whole meal, the main component of a horse’s diet. It delivers calories, protein, and carbohydrates and as part of the carbohydrates, the most important element: fiber! Horses are hindgut fermenters; the microbes that live in their cecum and colon digest the fiber and produce molecules the horse can use for energy. Without fiber these good microbes would die, the horse would have no energy and worst of all the bad microbes (Salmonella and Clostridum to name a few) would take over and then we’re really in trouble.
