| This experiment aimed to study the effects of palm kernel cake (PKC) substitution for ground corn (GC) in concentrate on the utilization of nutrients and on the rumen ecology in Thai indigenous cattle. Five rumen-fistulated native bulls, with an average live weight of 317±21 kg were randomly assigned according to a 5×5 Latin Squares Design to receive five diets containing different levels of PKC (0, 25, 50, 75 and 100%) substitution for GC. Plicatulum hay was offered ad libitum. Based on this experiment, the amount of plicatulum hay intake was linearly increased while the amount of concentrate intake and the total dry matter intake were linearly decreased as a result of an increase in level of PKC substitution for GC in the diet.
