Evolution of feeding behavior traits during the feeding test period. X axis denotes the age (days), and Y axis denotes daily mean of each feeding behavior trait. Error bars are illustrated on the plots. The data from the last day was removed, since ducks are considered to be under stress during this fasting period. Ducks were 19Â d of age at the beginning of the experiment. a Daily feed intake (b) Number of daily visits (c) Number of daily meals (d) Daily feeding rate (e) Daily meal duration (f) Between-meal pause
