Precision feeding (PF) technology has been developed to feed individual broiler breeders based on real time BW. Precision-fed broiler breeder chicks undergo training up to 21 D of age to learn how to eat from the PF stations. Training is crucial to achieve high flock uniformity and successful growth from a young age. An automated marking system (AMS) prototype has been integrated into a PF station to identify chicks that require training from those that have successfully learned to eat from the stations: chicks marked with dye have successfully visited and eaten from the feeder, whereas chicks with no or little dye are late adopters that require training. Before implementing the AMS on a larger scale, it was necessary to determine if dye markings from the AMS promoted aggressive behaviors among chicks. In the present study, the dye markings promoted aggressive pecks at 26 D of age; however, this is beyond the time the AMS is required as an identification method in a PF system.

An automated marking system (AMS）原型已集成到PF工位中，以识别需要从已经成功从该工位学到饮食的那些人中进行训练的雏鸡：标有染料的雏鸡已成功访问并从饲养者处食用，而没有染料或很少染料的雏鸡是较晚采用需要培训。在大规模实施AMS之前，有必要确定AMS的染料标记是否促进了雏鸡的侵略行为。在本研究中，染料标记在26 D岁时促进了攻击性啄木鸟。但是，这超出了将AMS用作PF系统中的识别方法的时间。
