The Missouri Fox Trotter is a medium-to-large breed with moderate energy demands that shift considerably depending on workload. A trail horse covering fifteen or twenty miles on mountainous terrain in a weekend burns far more calories than one used for light pleasure riding a few times a week. Understanding where your horse falls on that spectrum is the single most important factor in choosing the right feed program, because both underfeeding and overfeeding carry real consequences for gaited breeds.
Forage should form the foundation of any Fox Trotter's diet. As a general rule, horses need roughly one-and-a-half to two percent of their body weight in forage daily, which for a typical Fox Trotter translates to somewhere between fifteen and twenty-four pounds of quality hay or pasture equivalent. Good grass hay or a grass-legume mix is usually ideal, providing steady energy without the caloric density that can push an easy keeper toward obesity.
Protein requirements for adult Fox Trotters in moderate work generally fall in the ten-to-twelve percent range. Growing horses, lactating mares, and horses in heavy trail work may need slightly more. Fat and fiber are equally important macronutrients to monitor. Fat provides concentrated, slow-release energy that supports stamina without the metabolic spikes associated with high-starch feeds, and fiber keeps the hindgut functioning properly.
Minerals and vitamins round out the picture. Calcium-to-phosphorus ratios should stay in the neighborhood of two-to-one, and salt should be available free-choice at all times. Many Fox Trotters do well with a ration balancer or a loose mineral supplement to fill gaps that forage alone may not cover, particularly if the hay is regional and lacks certain trace minerals like selenium or copper.
