As winter comes to an end and warmer weather is on the way, it’s important to know what condition your supplements are in. Heat can cause oils, such as corn oil, and even powdered fat-based calorie-boosting products to go bad within a few days. The best place to store such supplements is in a refrigerator in the feed room, but if that’s not possible, keep only small amounts on hand and store the rest in a climate-controlled house or garage.
Tip: Pay close attention to the color, texture, and smell of your products.
Oil products that spoil may change in appearance, becoming darker or cloudy, or they may take on an unpleasant smell. Powdered fat products tend to clump as they pick up moisture and spoil. At best, feeding spoiled supplements will cause your horse to refuse to eat the meal, but it could also make him ill. Any change in the appearance or smell of a supplement is a good sign to toss the remainder and order a replacement.
