Bran Mash Myths: Should You Really Feed It?

You’ve probably heard plenty of bran mash myths floating around the barn — like giving your horse a warm bran mash when the temperature drops to prevent colic. The logic sounds comforting: warm bran keeps horses hydrated, and wheat bran supposedly helps things “keep moving” in the gut thanks to its mild laxative effect. This is an age-old tradition that many horsemen and women swear by, often handed down through generations.

But here’s the truth behind these bran mash myths: horses thrive on a consistent, balanced diet. Sudden changes — even something as seemingly harmless as a warm bran mash on a cold night — can actually do more harm than good. Your horse’s digestive system relies on specific enzymes, which adapt to break down the regular feed they eat daily. Introducing bran mash abruptly doesn’t give those enzymes time to adjust, which can upset your horse’s gut and increase the risk of digestive issues rather than prevent them.

Bran Mash Myths Debunked- What Should You Do?

So, what should you do instead when the weather turns cold and you want to pamper your horse? Rather than offering a bran mash out of tradition, try adding warm water to your horse’s regular grain. You can mix in a few apple or carrot peelings to make it more enticing, and a pinch of salt or electrolytes to help maintain hydration. This way, you keep the meal familiar to your horse’s system while adding the warmth and moisture that many owners love about bran mash.

At the end of the day, understanding the truth behind bran mash myths helps you keep your horse healthier, happier, and on a diet that truly works for them — even when temperatures drop.
