| Outline of Final Research Achievements |
Exposure of Japanese Black cows to the human approach tests, novel object test, feeding-sociability trade-off test, social isolation and restraint test, between-pastures movement test, maze test and food search test showed the usefulness of the human approach tests, trade-off test, social isolation and restraint test, between-pastures movement test and maze test for evaluation of cattle personality. Examination of the method for the novel object test provided critical information (condition of novel object presentation and behavior to be measured) for standardizing this test. Experiments on grassland showed that forming a cattle herd with a leader animal in group movement enhances the spatial evenness of grassland utilization by the herd, and that cattle can associate a visual cue with a food reward within a day and retain the association for 1 year despite a slight decay.
