Influence des stimulations auditives sur le comportement sexuel du taureau

Summary In a preliminary series of experiments, it was noted that dairy bulls who refused to mount the cow for a long time, could be induced to mount it again when acoustically stimulated by specific calls of cows emitted by a magnetophone. In these conditions, the reaction time of the bulls was also shorter, while ejaculated quantities did not differ from those obtained before the experiments. It is suggested that this rather simple procedure could be helpful when the use of bulls as teasers raises difficulties.
