Abstract
In order to investigate the influence of feeding level on the efficiency of energy utilization in fattening of Korean native cattle, a metabolic experiment was carried out with four mature Korean native cows by latin square method. After determining 1.5kg mixed hay and 2.6kg concentrate mixture as the amounts for maintenance, 1.5, 2.0, 2.5 and 3.0 times of the amounts of maintenance were calculated and fed to each of cattle successively by the feeding schedules. The regression equations between the energy intake and the proportion of energy deposited were made. The results above suggested 249.7 Kcal ME and 136.1 Kcal net ME per metabolic body size daily should be fed to maximize the proportion of ME deposition and net ME deposition. At this point daily DM intake was about 2.2% of body weight.
