This study quantifies feeding behavior of the W-36 White Leghorn laying hen (77-80 weeks old) as influenced by the management practice of beak trimming. The feeding behavior is characterized by a newly developed measurement system and computational algorithm. Nontrimmed (NT) and beak trimmed (BT) birds showed similar meal size. BT birds spent longer time at the feeder, which is compatible to their slower ingestion rate of 0.9 g/min vs. 1.3 g/min of the NT type. Compared with NT bird, the BT bird had smaller time intervals between meals, 200 vs. 450 s. By scientifically characterizing the feeding behavior of laying hens, baseline information will result that may help better quantify the welfare of birds.(Download PDF) (Export to EndNotes)
