Can I overdo bran mashes? I’ve been giving more with the long spell of subfreezing weather. SH, Tennessee
Dear SH,
Unfortunately yes. As much as we love to prepare a warm, tasty bran mash with our horse’s favorite ingredients, this traditional treat may be doing more harm than good. Turns out bran mashes upset the nutritional balance of the diet and may not even prevent or treat the problems we’re giving it for in the first place.
One of the problems with bran mashes is the imbalance in the calcium to phosphorus ratio. Horses should get somewhere between 1 part calcium to 1 part phosphorus (1:1) or 2 parts calcium to 1 part phosphorus (2:1). Bran has a ratio of 1:12, which means it has a lot more phosphorus than calcium. Creating an upside-down balance between these two important minerals can lead to a condition called “Big Head Disease,” where the horse pulls calcium out of its bones in order to rebalance the ratio.
Another problem with a weekly bran mash or an occasional bran mash before or after a trip is that it is a sudden change in the horse’s diet, something we’re taught never to do. The beneficial bacteria that live in the horse’s GI system need time to adapt to any new feeds. Bran is made up of complex carbohydrates that require bacteria to ferment them so it especially needs this “break in” period. Some of these complex carbohydrates are completely indigestible in the horse, so bran does tend to “bulk up” manure. However, research has shown that even when as much as 50% of the diet consists of bran there is still no laxative effect. Any stool softening or additional water you see in the feces after feeding bran is more likely diarrhea from a sudden change in the diet.
So if you’re feeding a bran mash to heat your horse up from the inside on cold winter days, try feeding more hay. If you’re feeding a bran mash to get more water into your horse, try adding electrolytes to the diet (and using heated buckets—studies prove horses drink more water when it is warmed). If you’re feeding a bran mash to bond with your horse, there are lots of other things you can do to remind him you’re his friend such as extra grooming, carrot stretches or clicker training.

I’m feeding a bit of bran mash 3x/day to get some medication (Ranitidine) into my horse – he gets about a cup of mash with a handful of sweet feed. He’s still getting his daily grain (the mashes are at “off times”) but a bit less because of the added mash. Vet said this would be OK, trying to keep his stress level down due to ulcers. Started a week ago and am supposed to continue a month….
Hi Mary, what a thoughtful question! It sounds like you and your veterinarian have worked out an excellent arrangement to get necessary medication into your horse. Since you’re feeding a small amount, you’re feeding it every day, and you don’t plan to continue past a month, all the issues pointed out above that have to do with long-term, irregular feeding of large amounts of wheat bran mash don’t apply in your case. – Dr. Lydia Gray
I’m feeding a wet mash of beet pulp/timothy grass pellets (1:1) plus 5 pounds Triple Crown Senior and 3 handfuls of chopped alfalfa to my elderly mare who cannot eat hay…she doesn’t have enough teeth left. She gets loose stools, but I’m thinking soft in….soft out??
Hi Karen, your mare is lucky to have you as a care-giver! Fortunately, the “mash” you describe doesn’t contain wheat bran, which is the culprit here, so have no worries about feeding a wet mix of beet pulp, grass pellets, senior feed, and chopped alfalfa. Yummy! – Dr. Lydia Gray
I have been giving all the horses at my barn a warm bran mash with one cup of mineral oil once a week. The vets I have talked to said it is a good practice. And colic is not a problem here.
Our horses receive a daily scoop of hay cubes in addition to their hay, and on some of these very cold evenings when they come in from their “snow pastures,” we’ve been adding warm water and a handful of bran as well as some carrots and apples to their hay cubes. Would this be considered detrimental as well? Thanks.
Hi Ellen, thanks for your question. Call me old-fashioned, but I firmly believe that horses’ diets should not be abruptly altered by adding a new feedstuff on an occasional basis. Plus, research shows that changes in hay increase a horse’s risk of colic by 10 times while a change in grain raise the odds by a factor of 5, and that’s enough evidence for me to just toss extra hay for more warmth when the polar vortex strikes. – Dr. Lydia Gray
Is feeding warmed up beat pulp a good idea to supplement and how much dry product do I start with?
Hi Mary, good question! While adding a delicious treat like this can make you feel like a Super Caregiver, really all your horse needs on colder days is more hay. Being high fiber, these complex carbohydrates make it all the way back to the cecum and colon where microorganisms ferment the hay to the end product of energy, which equals calories and warmth. So to make your horse feel warm from the inside out–and not risk disturbing his delicate GI balance by suddenly introducing a new feedstuff–just toss him an extra flake or two of his regular hay and he’ll thank you! – Dr. Lydia Gray
What supplement do you recommend for Navicular? My horse just got diagnosed with it.
Hi Sheri, first off, it’s very good that you’re working closely with your veterinarian and farrier to correctly diagnose your horse. With this condition, prescription medication might be appropriate, so working closely with those two professionals is the best way to go. I’ve also included an additional blog article that focuses specifically on this condition: http://blog.smartpakequine.com/2011/12/navicular-heel-pain-giving-you-a-headache/. It’s full of good information, and I think you’ll find it helpful! – Dr. Lydia Gray
does rice bran carry the same inadequacies?
Hi Marilyn, thanks for your excellent question! In fact, rice bran DOES have the same calcium to phosphorus imbalance as wheat bran so if you are feeding it, make sure it has been fortified (with extra calcium). Also, check the label to make sure it has also been stabilized to protect the high levels of fat it naturally contains. – Dr. Lydia Gray
I’ve been giving my horse beet pulp for going on 6 months now cause no matter what I have done she will not gain weight and this seems to help her. I’ve had her wormed an a fecal done, teeth were done and she was treated for any ulcers which she has none. She gets all the hay she can eat and gets it in a slow feed net to slow her down. She is a 4 year old filly off the track. Right now she gets unlimited hay and my winter grass 3 quarts soaked beet pulp and 3 quarts of equistages. And she gets this twice a day.
I can not do three feedings a day right now and I have tried senior feed and weight supplements.
What else can I do? Should I stop the beet pulp?
Hi Kristin, first of all I give you a lot of credit for all of the great things you’re doing to help your horse achieve a healthier weight. At this point, I think an important next step is to have an in-depth conversation with your veterinarian to try and determine why your horse has continued to struggle to put on weight despite your excellent efforts. You could consider asking your veterinarian if a weight gain or digestive support supplement might be an option as it sounds like this is not a piece of the puzzle that you’ve tried so far. Also, you might find the additional blogs below helpful. I wish you luck! – Dr. Lydia Gray

I have a friend with 2 miniature horses. Every day she mixes bran and water and pours it on their feed. Do you think it is necessary? After reading this article, I question the practice.
Thanks!
Hi Pat, because bran mash is not correctly balanced for a few key minerals, such as calcium and phosphorus, it is not advised to feed this on a regular basis to horses. Depending on what your friend is trying to achieve with feeding bran mash daily, there are very likely much more suitable options to achieve the same end. – Dr. Lydia Gray
Where i board my horse, its a handicapped program and they use my horse for the kids its awesome, they give wheat bran mixed with some water so it helps for sand or colic only in morning with feed does that hurt the horses? I read the article so now I’m a little worried .
Hi Susan, what a cool job your horse has now, he must be a very special guy. Because these bran mashes have an inverted ratio of calcium to phosphorus, it is not recommended to feed them to horses on a daily basis. Creating an upside-down balance of these minerals can lead to a condition called “Big Head Disease”, so I would encourage you to reconsider feeding the bran mash daily. There is no evidence that feeding bran mash helps to clear fecal sand, so if that is part of the goal, you’ll be better off looking into a psyllium-based product that is fed one week out of the month (called a purge). There truly isn’t a good reason to feed bran mash daily when considering the negative effects, especially when better and more effective options are readily available. – Dr. Lydia Gray
Seems like a few clarifications could be made to your article to keep from worrying people. I have to read comments to get out of it that you are talking mostly about wheat bran and you are talking about sudden changes in diet. Most brans such as rice are fortified with calcium to ensure the proper ratios of calcium to phosphorus. I for one feed rice bran year round because my mare cannot digest grain and she has diarrhea on grain. I research extensively what I feed and when I read your article I had to pause for a second.
I’ve been watching a sarcoid in my 12-yr. old AQHA gelding’s ear for almost four years. At first, it was a stalk that fell off on it’s own. Now, it is a round ball the size of a piece of jaw breaker candy. At present, it does not bother him, it does not bleed and he allows me to touch the ear. He wears a fly mask when outdoors.
What should be done, if anything, for this sarcoid? I want to be prepared to give my horse the best treatment available with the highest possible chance of curing the sarcoid. Thank you.
Kathy, I applaud you for wanting to give your horse the best treatment possible for this benign skin tumor. Therefore the best thing to do is to work closely with your veterinarian who will know the most up-to-date treatment protocols for managing sarcoids and preventing their recurrence. Hopefully together you can develop a program of observing and taking action when necessary. – Dr. Lydia Gray
At the barn I board my horse they give a scoop of bran with oils once a week after regular feedings… Is this harmful?
Hi Emily, thanks for asking! Because bran mash is not correctly balanced with the important minerals, calcium and phosphorus, it is not ideal to feed to horses on a regular basis. Also, when fed on a weekly basis, the bran mash can present a challenge for the bacteria in the hindgut to ferment, which can spell bad news for the horse’s hindgut. For these reasons, I encourage people to look for alternatives to bran mash whenever they can. – Dr. Lydia Gray
While bran is harm for horse , why some compues put the bran in their prodcuts?????
I have been feeding 4 cups of stabilized rice bran daily to keep my ‘hot’ horse’s weight up (without the frenzy) for about 6 months. Supplements included are Smartvite Thrive Senior Pellets (he’s 24) Cosequin, 1/2 c Omega Horseshine and Source (minerals)
Is there enough calcium in the supplements to offset deficiency in Rice bran? (Smartvite has 3000 mg calcium)
He really loves it and it seems to be keeping him in great condition.
Also free choice grass hay. Alfalfa is too hot for him.
All this discussion about wheat bran is prompting me to ask…..
Every day I give my horse half a cup of wheat bran twice a day mixed in with her half cup of LMF-G Super Supplement and half cup of timothy pellets w/rice bran. Since that’s only a grand total of one cup per day, do you consider this an issue? I’ve had her three years and have never once had an issue with her when it comes to her health. I’m hearing nightmare stories about the evils of wheat bran and would like to know what you think of her cup a day. She also gets orchard grass hay and one scoop of Redmond’s Daily Gold in the a.m. I never do the mega dose of wheat bran.
Thank you for your question! One of the problems with adding bran mash to your horse’s diet is that it can cause an imbalance in the calcium to phosphorus ratio in your horse’s diet. We’d recommend checking in with your veterinarian, an equine nutritionist or a resource like FeedXL.com to see if the amount you’re feeding is of concern. They’ll be able to take a look at your horse’s entire diet to make sure that everything is properly balanced and appropriate for your individual horse.

In the winter (in Vermont where it is really winter at times) I add warm water directly to my horse’s pelleted feed which quickly turns to mash all by itself. When it is below zero I add a cup or two of wet beet pulp as well. Is that too much of a change? Is it enough to stress them out?
[Actually last winter it was cold so long and regularly that they were getting beet pulp pretty much daily for a month or two.]
I also give them more hay as the temperature drops, below zero it is free choice and they usually have hay leftover.
Adding extra hay during colder months like you’re doing is the first and best option whenever possible. The complex carbohydrates in hay make it all the way back to the cecum and colon where microorganisms ferment this long-stem forage, creating heat (warmth) as well as calories. Beet pulp is also a fermentable food, but an occasional serving can be stressful to your horse’s digestive system. So to avoid disturbing your horse’s delicate microbial GI balance by suddenly introducing a new feedstuff, continue offering extra hay when the temperature drops and give beet pulp every single day during the winter months, not just occasionally. Of course, your local vet is your best resource for the most appropriate diet for your horse, so be sure and talk to him or her about this same topic. – Dr. Lydia Gray
My horse gets about 6 cups of wheat bran almost daily since a bad colic last winter. This article scares me. What damage could have been done and how do I wean her off it?
No need to be scared, especially when you’ve already been through a difficult situation with your horse! Unfortunately, the risks of feeding regular wheat bran – with its inverted calcium to phosphorous ratio – outweigh the benefits it may have to horses at risk for colic. Ask your veterinarian if there might be other options for keeping your horse’s digestive tract happy and healthy, such as adding water to beet pulp, complete feed, hay pellets, or another balanced feedstuff, or even feeding long-stem hay from a small-hole hay net so your horse nibbles throughout the day as nature intended. Your vet will also be able to help you gradually make the transition from daily wheat bran to a healthier solution. –Dr. Lydia Gray
My father fed hot bran mash every day in the winter,lots of it. Must of been bad for them they only lived 25 or more years. Always healthy!
I hope I’m not re-asking a question! But I read a similar article 3 months ago about bran and about the disadvantages of disrupting their normal diet once a week for a mash but read that it could be helpful to add a small amount to their daily feed in order for them to be used to having it in their diet. But reading about the downside of the nutrition value I’m concerned that I should just stop feeding it all together?
Hi my elderly mare has trouble keeping weight on and I’m feeding her beet pulp mixed with grain and weight builder supplement. I’ve been adding about 1/2 a cup to 3/4 of a cup of bran to this to make it a little more interesting and just to change up the taste a little bit. If I am feeding this little amount daily long term will this harm her in anyway? Just wanna make sure what I’m giving her is perfectly safe. Thanks!!
Hi Paige,
It sounds like you’re working hard to help keep your senior mare a good weight! That’s great! It is possible that feeding bran long-term can alter your horse’s calcium to phosphorus ratio but whether or not the amount you are feeding is enough to be an issue will be dependent on the rest of her diet. There’s a great resource called FeedXL.com that you may find useful! It helps horse owners evaluate their horse’s entire diet as a whole. We’d also recommend checking in with your veterinarian to review your mare’s diet and also to determine if there are any underlying issues contributing to her struggles with her weight.

I just received this was wonder what I should feed or give her is the bran mash ok..
I saw that she is lacking a bit of the stomach digestive fluid and the intestines were showing food was passing but going through slower than normal. As a precaution, please give her a nice warm very wet bran mash
It’s important to understand that this article is based on faulty arguments. Let me explain. If your house is on pasture (which it should be) or even hay you don’t always know what ratios it just ate. It might have consumed a high ratio of calcium to phosphorus. But later it might eat a plant that has a lower ratio. But what this article misses is that whole food contains organic nutrients with the horse or human assimilates what it needs and poops the rest. Supplements and processed fed contain inorganic nutrients and are largely not bioavailable but inorganic nutrients are treated differently and they are often stored in the body and cause issues later on.
A good food like bran mash can be eaten a few times a week by your horse for good health. It is not bad for them. In fact when soaked it is very vey good for them.
Butt the point is organic whole food is not the same as processed fed and processed fed is responsible for most of our diseases in horses. Colic is largely caused by processed feed but nobody talks about that – because there is too much money in it. So we discredit natural whole food like bran, oats, peas, that are used very effectively in the UK and other parts of the world where their horses are healthier and live longer and have less disease.
Read her handbooks from 20-100 years ago. They largely used herbs and largely recommended whole foods and had LARGE success. I have researched this extensively.
Read *vet handbooks
Sorry typed this on my phone and it changes everything so sorry for typos
My father-in-law went to race horse school where they fed hot wheat bran mash,,,so cominf from a school I would think this is a good thing for your horse. I have been feeding mash to my trail horses in the winter months, starting with small amounts gradually increase to 3/4 coffee can with water and their reg feed amount once a day, usually in evening feeding,,,,I have never had any problems, actually no health issues ever, and wherever we go people comment on how healthy our horses look.they go in and out of barn whenever they want free access to pasture, hay in am & pm,,,I fed beetpulp to a mate I had once and she almost choked to death,,,water hose down the thoart saved her,,,never beet pulp again, I’m just saying this is what works for me,,,my grandfather said once to me, keep your horses as natural as possible,,,good luck to u all and your equine buddies
Which is the better supplement to feed for weight gain? Rice bran or beet pulp. Currently feeding beet pulp.
I have minitures ranging in age from 7 years to 19 years. All in good health.
Is there anything I should be feeding them other than good quality hay ?

Hi Kathleen, So great to hear that your horses are in good health and that forage is the foundation of their diets! I commend you for being so on top of their feed programs and ensuring they are only getting the best. Depending on the use of your horses, if they are on a hay-only diet chances are that they may not be getting all the nutrients they need. Even horses grazing 24/7 on high-quality pasture may still require mineral supplementation. So at a minimum, consider adding a multi-vitamin/mineral supplement to their diet that is balanced for their unique age and workloads.
Salt should always be available, and I’m more of a loose-salt fan than traditional salt block fan because I think horses are more likely to get what they need when they don’t have to lick a rough substance. I like the new smooth, hard rock salts though. Just keep in mind they are mostly sodium chloride and don’t provide enough other minerals to meet your horses’ nutritional needs. Of course, your local vet is your best resource for the most appropriate diet for your horse, so be sure and talk to him or her about this same topic. – Dr. Lydia Gray
Our horse 16 year old Oldenburg is going to college with my daughter the end of August. It will be around a 6 hour drive. I am wondering if you suggest that we give him electrolytes and a bran mash the week we are leaving. He tends not to drink a lot when we show and I am concerned about traveling with him that trip without drinking. We will make a few stops along the way to offer him water but more than likely he will not drink it. This will be the longest drive we have taken with him. We do have him on quintessences and ultra shield and he also takes Previcox as well. Thank you for your assistance.
