| Resumo: |
This study aimed to evaluate the effect of including of palm kernel cake on feeding behavior of lactating crossbred cows. Twelve crossbred Holstein x Zebu cows were distributed in three 4 x 4 latin squares, with the following treatments: control; inclusion of 5%; inclusion of 10%; inclusion of 15% palm kernel cake in the diet dry matter. The animals were observed during four periods as to feeding behavior, 24 hours in each period. There was no effect of inclusion of palm kernel cake (p > 0.05) on time spent on eating, ruminating and idling. The feeding efficiencies of dry matter and corrected neutral detergent fiber, total digestible nutrients, and the rumination efficiency of corrected neutral detergent fiber were not influenced (p > 0.05). There was a linear increase with the inclusion of palm kernel cake (p < 0.05) for the efficiencies of rumination of dry matter and total digestible nutrients. The number of periods and duration of behavioral activities was not affected (p > 0.05). The inclusion of palm kernel cake in diets for dairy cows causes no change in behavior activities and efficiencies of feeding and rumination, until the 15% level of inclusion.
