What’s a feed? An equine feed is most often sold in large bags with recommended feeding rates of five pounds per day or more, sometimes much more. The most common source of energy in feeds is a blend of grain and grain by products. The protein source in most feeds is also usually grain based, but, in low quality feeds may be from other sources
Many feeds are formulated to meet their printed label guarantees at the lowest cost by reformulating every week with different components. This is called “least cost formulating”. While the protein, fat and fiber levels may be the same from bag to bag, the actual product inside may not be. In general, the easiest way to spot a “least cost formulated” feed is to look for a tag on the bag that lists the nutritional information rather than having that information printed directly on the bag. If the manufacturer is constantly changing the formulation as ingredient pricing varies, it is easier to change the ingredient list on a tag than on a pre-printed bag.
