| Outline of Final Research Achievements |
This study was to clarify the molecular basis of cannibalism (Experiments 1 and 2) and to develop a robot-based system to manipulate chick behavior (Experiment 3). In Experiment 1, a population genome analysis of the whole genome sequencing information of military chickens was used to search for the genetic basis that controls the pattern of aggressive behavior. In Experiment 2, the frequency of feather pecking was evaluated using feather scores to find populations of commercial chickens that differ in the frequency of feather pecking, and a search for the genetic basis controlling feather pecking was conducted as in Experiment 1. In Experiment 3, we developed a robot equipped with elements important for imitating mother-offspring behavior and presented it to chickens, suggesting that changes in behavior and weight gain occur.
