For many years feeding bran to your horses was a normal practice especially before a lot of the new premixed feeds were available. However now in the day of supplements and new advances in feeds, is this still a good thing for us to be doing, or is this now very much outdated, and is bran really that bad for my horse?
Bran has often been fed for various reasons:
🐴 A bran mash can be a tasty treat on cold wet days
🐴 You can add other things to it such as molasses, steamed grains (oats or barely), carrots, etc which all add nutritional value.
🐴 For hydration, adding salt to a bran mash can encourage drinking, plus the added moisture content of the mash.
🐴 As a mash, it can assist with fussy eaters and disguise medications.
🐴 For horses that have gone off their feed, whether it’s due to them being unwell or age-related issues such as poor teeth.
🐴 And one of the most common reasons it has been used over the years is the belief that it is a good source of fibre and can be used as a laxative, therefore making it helpful with colic.
With all-new advances and research into horse nutrition, we can now see why bran may not be as beneficial for our horses as we used to believe
Bran is the byproduct of flour milling. Bran has quite a high phosphorus level, 10 times higher than calcium. As a rule, horses require a calcium to phosphorus ratio of 2:1 (2 parts calcium to 1 part phosphorus), this mirrors the levels found in horses’ own bones and really should not drop below 1:1. The higher levels of phosphorus found in bran can decrease a horse’s ability to absorb calcium from their diet, and in doing so they will start to draw on calcium from their bones. This has the effect of weakening their bones, leading to what we call Big Head syndrome, or once referred to as Miller’s disease, (named for the fact that years ago horses that worked in the flour mills used to be fed the byproducts of the milling process).
As we all know any change to our horse’s diet should be gradual so that the bacteria in a horse’s hindgut can adapt, with minimal upset. Feeding bran at random intervals could therefore cause digestive upset and is potentially where the idea that bran has a “laxative effect” originated, leading to the thought that it is beneficial for horses that may suffer from colic.
Horses require a high level of fibre however bran is in fact, quite low in fibre. We all like to think giving our horses a nice warm bran mash on a cold day is a nice treat, but due to its low fibre content, bran actually won’t warm your horse up. Feeding hay or other forage will have a much better warming effect, due to the way a horse’s hindgut ferments fibre.
