One of the most frequently asked questions regarding feeding the performance horse is when to feed before a competition. Several studies have evaluated how feeding grain before exercise affects plasma concentrations of nutrients.
and hormones and substrate utilization during exercise. A series of
experiments was conducted to first evaluate how feeding forage along with grain
influences plasma variables and water intake and then to determine whether these
changes affect exercise performance.

Every equine practitioner appreciates the delicate nature of the equine gut. Problems related to the
small intestine and large intestine are well understood and routinely treated. What may be surprising to many is how often the stomach is affected.

Minerals required in minute amounts by horses are specified as microminerals. These nutrients play an important role in a wide range of biochemical systems which affect virtually every metabolic function in the horse. With the exception of selenium, little attention has been given to microminerals in horse nutrition until shortly before the publication of the current NRC Nutrient Requirements of Horses in 1989.

Little is known about voluntary salt intake in horses. Therefore, the purpose of the present study was to
measure the voluntary intake of loose versus block salt over time and evaluate how salt intake affects water consumption.

Mineral requirements for horses are usually calculated using information about
the horse’s body weight, age, weight gain, physiological status (pregnancy, lactation,
etc.) and level of activity.This paper will review some of the most important factors affecting the
digestibility of minerals in horses and will use data from a series of digestion trials
conducted by Kentucky Equine Research to illustrate how relevant nutrient interactions
are in typical horse rations.

Hyperglycemia and hyperinsulinemia have been implicated in the pathogenesis of osteochondrosis (Glade et al., 1984; Ralston, 1995). More specifically, foals that experience an exaggerated and sustained increase in circulating glucose or insulin in response to a carbohydrate (grain) meal may be predisposed to development of osteochondrosis.

The purpose of this study was to examine the effects of an external nasal strip (NS), frusemide (FR) and a combination of the 2 treatments (NS + FR) on exercise-induced pulmonary hemorrhage (EIPH) in Thoroughbred horses. It was hypothesized that both the NS and FR would attenuate EIPH as assessed by red blood cell count in bronchoalveolar lavage fluid.

Reproductive efficiency in the mare is lowest among domestic livestock. Researchers set out to determine if this may be partly dependent on vitamin A status of mares. To test […]
