It is the rapid increases and decreases in glucose and hormone levels which cause them to become over-sensitive. The horse's body can't determine the source of a calorie and uses some sources for activity and others for growth or fat deposits, Rich adds. The cells use the calories indiscriminately, regardless if they are from corn or oats. When we increase the level of fat and decrease the amount of grain or starch in the diet, we can provide the horse with an adequate amount of energy that meets his activity level. Nutrients such as minerals, vitamins or amino acids can also affect a horse's behavior through their specific roles in metabolism.
Some horses can become hyperactive when they are deficient in certain minerals and vitamins.
Other horses, however, may become less active when missing these same nutrients. Visit our Contact Us page.
