dc.description.abstract <p>This study quantifies feeding behavior of W-98 White Leghorn pullets (1-3 weeks old) as influenced by the management practice of beak trimming. The feeding behavior was characterized using a newly developed measurement system and computational algorithm. Beak trimmed (BT) pullets and non-trimmed (NT) pullets exhibited significantly different eating behavior over the ages of 8 to 21 days with regard to meal size and meal duration. Beak-trimmed birds tended to eat larger and longer meals, although the differences between the BT and NT birds were not constant with age (significant interaction between beak type and age, P<0.05). No significant differences across beak types or ages were detected for ingestion rate or interval between meals. The BT and NT pullets had similar amount of daily feeding time (1.1 - 1.2 hr/day). However, the number of meals per day differed, 28 meals/day for the BT pullets vs. 35 meals/day for the NT pullets. Baseline feeding behavior information of this nature may help better quantify and ensure welfare of the animals through exercising proper engineering design or management considerations.</p>
