With Dr. Ed Ott

Our experts explain the nuts and bolts of equine nutrition.

A. Unless the corn is of poor quality it is not likely to cause colic in most horses. Corn is one of the primary feed grains included in many horse feeds because it is high in energy and the most economical source of energy available. However because of its high energy content, we usually limit the amount of corn we feed. Overfeeding concentrates, whether corn or another type of grain, may cause colic and other digestive problems. Therefore, pasture or hay should provide as much of your horse's nutrient needs as possible, and concentrates should merely supplement the forage to provide adequate energy, protein, vitamins and minerals to support your horse's activity level.

Q. How much water should my horse drink in the hot summer months?

A. Water intake needs vary considerably between animals, but generally horses will drink 5 to 10 gallons per day. However, with heat and/or exercise this amount can increase up to 20 to 30 gallons of water per day. Horses that are either working or living in the heat lose considerable water in their perspiration and must increase their water intake to compensate for the loss. In addition, perspiration depletes electrolytes, so summertime heat warrants replacing sodium, potassium and chloride as well as water. The best solution to meeting the water needs of your horse is to provide all of the clean, fresh water he will drink at all times. If you stall your horses and water via buckets, clean and fill those buckets whenever they get low. If they are on pasture or in paddocks, a stock tank with an automatic valve will be the best choice. If your horse won't drink enough water to maintain proper hydration and you are providing adequate water, you may need to consider supplementing electrolytes or making the water more palatable.
