本研究通过对15-16头日本黑牛进行重复两次的五项试验，研究了肉牛对各种环境刺激的反应性。在个体行为测量中，奶牛中度（重复性=0.54-0.70）或高度（重复性=0.74-0.89）在人类接近测试中放牧和休息期间的飞行距离一致，在喂养-社交性权衡测试中与组围栏的最大距离和总的和不同的饲料桶访问次数一致，并且不愿意进入约束装置，在社会隔离和约束测试中，在约束下的运动和从约束释放后的飞行速度。相比之下，奶牛在新奇测试中第一次接触的潜伏期和接触新物体的次数并不一致（重复性=0.24-0.39）。在不同测试的行为测量中，奶牛在两种人类接近测试（权衡测试和社会隔离和约束测试）的任何测量组合中均未显示一致性（P0.05）。总之，人类的接近方式（特别是在休息期间）、喂养与社交能力的权衡以及社会孤立和约束情况可用于评估日本黑牛的个性，而新奇测试的价值需要重新审视。
This study investigated responsiveness of beef cattle to various environmental stimuli by subjecting 15-16 Japanese Black cows to five tests repeated twice. Within individual behavioral measures, cows were moderately (repeatability=0.54-0.70) or highly (repeatability=0.74-0.89) consistent in flight distance during grazing and resting in the human approach tests, maximum distance from the group pen and the number of total and different feed tub visits in the feeding-sociability trade-off test, and unwillingness to enter the restraint, movement under restraint and flight speed after release from restraint in the social isolation and restraint test. By contrast, cows were not consistent in the latency to make the first contact and the number of contacts with novel object(s) in the novelty test (repeatability=0.24-0.39). Across behavioral measures in different tests, cows showed no consistency (P0.05) in any combinations of measures from the two human approach tests, the trade-off test and the social isolation and restraint test. In conclusion, human approach (particularly during resting), feeding-sociability trade-off and social isolation and restraint situations can be used for evaluating personality in Japanese Black cows, while the value of the novelty test needs to be reexamined.
