The present study aimed to establish whether supplemental Japanese pepper seed (JPS) affects feed intake in broiler chicks under ad libitum conditions. Experiments were designed to estimate the acute effect of JPS on feed and water intake using 5%-20% JPS supplemental feeds. JPS supplemental feed demonstrated a tendency to suppress feed intake and water intake in a dose-dependent manner during the 2 h post-feeding period, and chicks seldom ate 20% JPS supplemental feed at 1 h post-feeding. No significant difference was observed in the rectal temperature between groups during the 2 h post-feeding period. In a 5-h feeding experiment, no JPS level had any effect on feed or water intake in chicks. These data suggest that the adverse effect of JPS may be due to volatile stimulation; however, the effect disappears after 5 h post-feeding.
