Intensive labor chores for broiler production could be reduced by using automated ***,broilers’response toward automated systems remains *** experiments were conducted to determine the avoidance distance(AD)and the fleeing speed(FS)of 4-8 weeks old broilers toward two aerial systems,a rail with a dummy arm and a drone,operated at different speeds(0.2-1.2 m/s),and heights(0.3-1.8 m)in a commercial broiler *** broiler AD to a human assessor was also determined for *** show that the overall mean and standard error(SE)of broiler AD were 63±3 cm for the assessor,58±1 cm for the rail,and 85±1 cm for the *** bird age increased from week 4 to week 8,broiler AD reduced significantly from 82 to 45 cm for the rail but showed no significant change for the *** the operational speed increased,broiler AD significantly increased from 54 cm(0.2 m/s)to 62 cm(0.4 m/s)for the rail,and from 81 cm(0.4 m/s)to 89 cm(1.2 m/s)for the *** the operational height increased,broiler AD increased from 54 cm(0.3 m)to 57 cm(1.5 m)for the rail and 81 cm(1.2 m)to 88 cm(1.8 m)for the *** mean and SE of broiler FS were 0.21±0.01 m/s for the rail and 0.65±0.01 m/s for the *** bird age increased from week 4 to week 8,the mean broiler FS decreased from 0.47 to 0.07 m/s for the rail and from 0.84 to 0.16 m/s for the *** operational speed from 0.2 to 0.4 m/s for the rail and from 0.4 to 1.2 m/s for the drone significantly increased the mean FS from 0.18 to 0.24 m/s and from 0.52 to 0.78 m/s,*** the height of the rail from 0.3 to 1.5 m decreased the broiler FS from 0.27 to 0.16 m/***,increasing drone height from 1.2 to 1.8 m retained a similar *** outcomes of this study can help to better understand the interaction of broilers with aerial systems and provide insights into the optimization of robotic operational strategies while maintaining good broiler welfare production.
