In addition to its well-known cardiovascular and muscle building benefits, regular exercise promotes digestive function and healthy weight management in horses. Fitness training also helps reduce the risk of injury and improves bone mass in working horses. Exercise also influences...
The horse's digestive system is both large and sensitive. It has evolved over millennia to absorb nutrients from grazing pastures and meet the unique energy needs of a free-roaming, incredibly athletic animal. As the horse evolved on the Steppes of...
Fiber is one of the most important components in the equine diet, providing up to 70% of a horse’s energy needs. Fiber in equines diets predominantly originates from forages such as hay and pasture grass. Fiber can also be obtained...
Psyllium is a rich source of soluble fiber that can be incorporated into equine diets. Soluble fiber remains undigested by enzymes in the stomach (gastric juices), but passes into the hindgut where it may be partially digested by microbes. Psyllium...
Oxalates are naturally occurring compounds that bind calcium in the equine diet, preventing absorption of this mineral from the horse’s gut. When horses consume plants with high levels of these [...]
A balanced feeding program is key for yearling horses, as it sets the foundation for their growth and development into adulthood. Yearlings are transitioning from foals to young horses, and their nutritional needs are unique during this stage of life.
