Feeding schedule during competition day in performance horses

Abstract

This review is focused on the feeding schedule during a competition day. Data from literature suggest that intake of a starchy meal should occur no later than 3-4 h before the onset of exercise (meal size < 0.3% of BW), and that supplementation of electrolytes 4 h before exercise is advisable because voluntary water intake is increased pre-exercise. Roughage should be provided without any limitations, especially before endurance competitions or three-day events. During endurance exercise, electrolyte application is useful only when water is available. Palatable feedstuffs such as steam-flaked corn or alfalfa provide extra energy; in addition, glucose intake (1 g glucose/kg BW) may support maintenance of higher blood glucose levels. After strenuous competition races, rehydration strategies are improved by addition of electrolytes to the water, or voluntary intake of water is improved by the application of concentrated electrolyte pastes or palatable feed mixtures with electrolytes. Hay ad libitum should be offered first to the horses after exercise; a starchy meal (meal size < 0.3% of BW) can be offered 2-4 h after cessation of exercise.
