Equine Energetics II: Energy Expenditure In Horses During Submaximal Exercise
Energy expenditure was measured in four geldings (433 to 520 kg) during submaximal exercise on a racetrack using a mobile open-circuit indirect respiration calorimeter. Total energy expended by the four horses walking, trotting, cantering was best described by the equation: Y = e3.02 + .0065X where Y = energy expended (cal X kg-1 X min-1) and X = speed (m/min).
Equine Energetics I: Relationship Between Body Weight And Energy Requirements In Horses
Energy balance studies using indirect calorimetry were conducted with four mature equids ranging in weight from 125 to 856 kg. It was concluded that the maintenance requirements of equids vary linearly with body weight. The digestible energy (DE) requirement for equids confined to metabolism stalls was DE (kcal/d) = 975 + 21.28 X W where W equals body weight in kg.
The Oxygen Cost Of Weight Loading And Inclined Treadmill Exercise In The Horse
This study was carried out to determine the metabolic response to load carrying and inclined trotting during treadmill exercise in the horse. Five standardbred trotters, trained for treadmill exercise, were subjected to an exercise test with and without 10% of their body weight in the position of a rider and saddle.
The Effect Of Dietary Energy Source On Exercise Performance In Standardbred Horses
Three standardbred horses were used in a 3×3 Latin square design trial to determine the effect of feeding diets containing different levels of carbohydrate, fat, and protein to exercise horses. Muscle and live glycogen concentrations were significantly lower after the long slow exercise test when the horses were fed high protein and high fat than fed the commercial sweet feed diet.
