Popis: The aim of this study was to evaluate the effects of dietary inclusion of palm kernel cake (PKC) on the feeding behavior of feedlot-finished cattle. Forty uncastrated crossbred bulls with an average age of 24.2 ± 2 months and an average weight of 331.1 ± 36.2 kg were distributed into four treatment groups in a completely randomized design with ten replicates. The treatments consisted of 0, 8, 16, or 24% PKC inclusion in the diet (dry matter basis). Palm kernel cake inclusion influenced feeding time (P 0.05) on neutral detergent fiber feeding (NDF) efficiency or DM rumination efficiency. NDF rumination efficiency increased linearly (P < 0.05). Palm kernel cake can be included at levels up to 24% in the total diet of feedlot-finished crossbred bulls, as it does not affect their dry matter intake or feeding behavior.
