Despite regular exercising and balanced feeding, does your horse still look like he or she is in need of a “tummy tuck?” If you’ve ruled out post-colic surgery effects, parasites and broodmare belly as the cause of the large gut, then it’s likely your horse has a nutritional imbalance. We’ve outlined answers to common questions so you can identify, treat and prevent a hay belly in your horse.

Q: How can I tell if my horse has a hay belly?

A: A hay belly is typically easy to recognize in young and mature horses alike. A hay-bellied colt or filly displays a big belly while the rest of their body looks small. A mature horse will often have a midsection that hangs low, yet their ribs are visible, and they will lack defined muscling across their hindquarters.

These obvious signs are a good start to identifying hay belly, but you should also conduct a regular body condition score on your horse to check muscle mass and appropriate fat deposition. Keep in mind that it’s important to check all areas of your horse’s body, including his neck, withers, back, ribs, shoulder and tailhead. A rib and belly check alone don’t provide all the answers.

Q: How did my horse develop a hay belly?

A: A horse develops a hay belly when they are fed too many low-value calories without adequate protein. His body still stores the calories as energy in cells, but he is unable to maintain muscle mass because protein is unavailable. This absence of protein causes muscle atrophy and an increase in stored energy, which means muscle mass is lost and gut size expands.

The biggest contributing factor is overfeeding Neutral Detergent Fiber (NDF) and underfeeding quality protein. NDF is the measurement of cell wall content in plants such as grass. As a plant matures, it builds stronger cell walls to hold itself upright. The stronger the cell wall, the harder it is for a horse to digest. Hay with high levels of NDF are often lower in quality proteins, which means a horse is missing out on important nutrients that help them develop and maintain muscle.
