Abstract
We experimentally examined whether the sub-group of female cattle could be separated from its large group and be guided differently by each of two kinds of music. SixJapanese Black breeding female cattle divided into two groups (three animals each), were trained to be guided by the one of two different music using concentrate feed as reward. As a result, auditory guidance was conducted successfully under the both training conditions ; 1) each group was trained independently, and 2) two groups were mixed and trained together using each different correct answer corresponding to each of two different music. At the latter condition, however, many trials (140-240 trial) was needed for its success, and the interruption of the subordinate's access to feed bunk by the dominant was observed. The further research on auditory discrimination guidance such as using negative reinforcement seems to be necessary for applying the result to practical situations.
