A system for automatic registration and individual recognition of feed pecking (activity and quantity) in groups of free running hens was tested. A PIT (Passive Integrated Transponder)-tag system was used to separate and register individuals when they were feeding. An electronic balance system placed under the feeder registered the amount eaten by each individual on a PC. A test with two different feed stuffs; oat and wheat was performed on three hens during a total of 6 weeks.
对一个用于自动记录自由放养母鸡群体中啄食行为（活动和数量）并进行个体识别的系统进行了测试。采用被动式集成应答器（PIT）标签系统在母鸡进食时对个体进行区分和记录。放置在喂食器下方的电子天平系统将每只母鸡的进食量记录到个人电脑上。用两种不同的饲料（燕麦和小麦）对三只母鸡进行了为期6周的测试。
