Q: I’ve been told I should feed beet pulp to help put weight on my skinny Thoroughbred. But I’m worried about the stories I’ve heard about beet pulp expanding in the horse’s stomach and causing colic—or worse! Is beet pulp a good addition to my horse’s diet, and if so, how can I feed it safely?

A: Beet pulp is the fibrous material left over after the sugar is extracted from sugar beets. It’s an excellent source of digestible fiber, with a relatively low crude protein content (averaging 8 to 10%), comparable to good-quality grass hay. Its digestible energy is somewhere between that of hay and grain. In terms of other nutrients, it’s not a stand-out–it has a relatively high calcium content and very little phosphorus, is low in B vitamins, and has virtually no beta-carotene (the precursor of vitamin A) or vitamin D. Its chief value is as a soft, easily digestible supplement to your horse’s roughage (fiber) intake, and as such it’s a useful addition to the diet of many types of horses.

Consider feeding beet pulp if your horse is a “hard keeper” (it’s very good for encouraging weight gain), if he has dental problems that make chewing hay difficult, if the quality of your hay is poor, or if you have a geriatric horse who has trouble chewing or digesting other types of forage. It can be fed in addition to, or instead of, hay. Beet pulp’s excellent digestibility also makes it a great choice for a convalescing horse–one recovering from illness or surgery, for example. It even can be fed warm in the winter months, just like a bran mash (and nutritionally, it’s a better choice than bran). Most horses find it quite palatable, although occasionally you’ll come across one who considers it an acquired taste.

In its original format, beet pulp is quite soft and prone to mold, so it must be dried for storage. You can buy dehydrated beet pulp in either a shredded or a pelleted format; either way, it’s grayish-brown in color and has a slight but distinctive odor you’ll come to recognize. Some companies add a touch of dried molasses to improve its palatability and energy content. Contrary to popular opinion, you don’t have to soak beet pulp in water to feed it safely to horses–studies in which horses were fed dehydrated beet pulp, up to a level of 45% of their total diet, noted no ill effects whatsoever. Not only did the horses not “explode” (thus laying that myth to rest!), but they also suffered no signs of colic or choke, nor did the water content in their manure change. But most people prefer to soak beet pulp; it’s more palatable that way, and less likely to cause choke
