Hoof Nutrition Intelligence is a twice-a-month web segment that is designed to add to the education of footcare professionals when it comes to effectively feeding the hoof. The goal of this web-exclusive feature is to zero in on specific areas of hoof nutrition and avoid broad-based articles that simply look at the overall equine feeding situation.
Below you will find Part 2 of the latest question and answer installment that you can share with your footcare clients.
Q: Should hay be fed before grain, or vice versa?
By Juliet M. Getty, Ph.D.
If you’re feeding correctly, this issue is truly a moot point because the horse should have access to forage in hay and/or pasture 24/7 with no gaps. Therefore, when fed concentrates, the horse's digestive tract should already have hay flowing through it.
But if you were to feed starchy cereal grains (oats, wheat, barley, etc.) on an empty stomach, the horse would produce more acid than normal, which could potentially lead to ulcers. Furthermore, grains leave the stomach quickly, increasing the risk that they will not be fully digested in the small intestine (especially if large amounts are fed), and end up in the hindgut where starch can be fermented by the resident bacterial population. This can lead to endotoxin-related laminitis.
A better approach is to have hay present in the stomach first. It creates a physical barrier for the grain, making it leave the stomach less quickly. The fiber in the hay mixes with the starch and the whole mass enters the small intestine to be digested. Fiber is not digested until it reaches the hind gut, but its presence slows down the digestion of starch, and obstructs the absorption of glucose into the bloodstream, leading to a less dramatic rise in insulin.

Hoof Nutrition Intelligence is brought to you by W.F. Young Co. (Absorbine).
Like many significant achievements, Absorbine® grew out of humble beginnings—and through the tenacity of someone willing to question the status quo. In this case, it was a young woman in late 19th-century Massachusetts: Mary Ida Young. Her husband, Wilbur Fenelon Young, was an enterprising piano deliveryman who relied on the couple’s team of horses to make deliveries throughout the Northeast. Inspired by Mary Ida and Wilbur’s vision, Absorbine® has continued to add innovative products throughout the years — products used every day by horse owners around the world. Which is why, since 1892, we’ve been The Horse World’s Most Trusted Name®.
