Bodyweight is a key indicator of broiler production as it measures the production efficiency and indicates the health of a ***,broiler weight(i.e.,bodyweight)is primarily weighed manually,which is timeconsuming and labor-intensive,and tends to create stress in *** study aimed to develop an automatic and stress-free weighing platform for monitoring the weight of floor-reared broiler chickens in commercial *** developed system consists of a weighing platform,a real-time communication terminal,computer software and a smart phone applet *** system collected weight data of chickens on the weighing platform at intervals of 6 s,followed by filtering of outliers and repeating *** performance and stability of this system was systematically evaluated under commercial production *** the adoption of data preprocessing protocol,the average error of the new automatic weighing system was only 10.3 g,with an average accuracy 99.5%with the standard deviation of 2.3%.Further regression analysis showed a strong agreement between estimated weight and the standard weight obtained by the established live-bird sales *** variance(an indicator of flock uniformity)of broiler weight estimated using automatic weighing platforms was in accordance with the standard *** weighing system demonstrated superior stability for different growth stages,rearing seasons,growth rate types(medium-and slow-growing chickens)and *** system is applicable for daily weight monitoring in floor-reared broiler houses to improve feeding management,growth monitoring and finishing day *** application in commercial farms would improve the sustainability of poultry industry.
