A digestion trial was carried out in order to determine nutrient digestibilities of a typical ration on 4 Thoroughbred race horses that belonged to Korea Racing Association. At the same time, the status of actual nutrient supply for 9 race horses was examined on the basis of those digestibilities obtained. Each digestion trial comprised 15 days of prefeeding and 8 days of sample collection. The average digestibility quotient obtained from the trial were 66.02(±6.32)% for DM, 67.97(±5.83)% for OM, 75.58(±3.63)% for CP, 82.65(±2.00)% for EE, 55.08(±7.96)% or CF, 39.97(±11.92)% for CA, and 67.77(±5.21)% for NfE. Daily requirement of energy corresponding to the sum of maintenance energy plus exercise energy, was drawn using the equations suggested by Pagan and Hintz(1986). Only a little difference was observed between energy requirement and daily intake, so that in case of the horses confronting the racing period, DE supply was quite close to DE requirement. On the other hand, horses out of racing period were under higher DE supply than DE requirement. Moreover, there existed large variations between energy intake and requirement.
