摘要：

Bunk attendance of 72 feedlot cattle (412 +/- 23.6 kg) was monitored for 86 d using radio frequency technology. Late morning and late afternoon were confirmed as primary ad libitum feeding periods. The system detected differences (P < 0.005) in feeding behaviour in response to level of feeding and frequency of meals.
