초록

The aim of this study was to investigate the behavioral changes of laying hens in an aviary system. In this study, 500 laying hens (Hyline brown) were held in an aviary system in a open-type poultry house. The behaviors of laying hens were recorded using CCD cameras and a digital video recorder. The data were scanned every 2 min to obtain an instantaneous behavioral sample. In the behaviors of laying hens, 'Feeding' and 'Drinking' increased from 3 d placing chick and stabilized after 5 d placing chick. 'Perching' increased from 19:00 to 05:00, while 'Nest visiting' increased from 06:00 to 18:00. 'Aggressive behavior' decreased gradually after 5 d placing chick. These results suggest that the behaviors of laying hens are changed rapidly for about 5 days after placing chick and the behaviors of the laying hens are almost stabilized at 5 d placing chick.
