202 - Nature versus the NRC: Utilizing an Understanding of the “natural” Diet of the Horse in Contrast to Defined Guidelines

A comprehensive look at nutrients available in nature compared to equine nutrient requirements and the modern diets we feed them. Horses can survive on a variety of feedstuffs that they ingest if they are relatively equine-specific and the horses’ forage requirements are met for basic gastrointestinal health. It is safe to say that some horses in the United States continue to be fed as “nature-intended” with 24/7 access to fresh pasture or adequate plant material and enough room to continually move and graze. Many other horses, however, have only limited or no access to pasture and their movement is greatly restricted via stall confinement or small areas to move. In addition, there is a wide variety in what we ask horses to do, from horses that are simply pasture pets, to horses performing as elite-level athletes in racing and competitions. And when we look at all these factors from a nutrition perspective, how do the nutrients provided by nature match up with the requirements as set by the National Research Council’s Nutrient Requirements for Horses? And how do these nutrients provided by nature compare to how we are feeding many modern horses today? This presentation will examine these factors and shed light on differences between the NRC nutrient requirements and what is provided by both nature and/or modern feeding practices in several scenarios, to identify areas of mismatch that could be potentially addressed or researched further in an effort to improve the health and well-being of horses.
