Remember the suns for how they grew
In the present study, 12 Hereford bulls approximately During sexual performance tests, an observer recorded the times at which the bulls exhibited ejaculations, mounts without ejaculation, mount attempts, mount intentions, head throws and Flehmen responses. The observer also recorded the percentage of time spent in proximity to the stimulus female and objectively rated the bulls for overall sexual performance and mating efficiency.
Relative to the control treatment, the greatest improvement in sexual performance was noted when the bulls had observed the copulatory activities of conspecifics. Sexual performance was improved, albeit to a lesser degree, by being watched by another male and by restraint in the presence of the stimulus female.
The advantages of sexual stimulation should be considered when breeding farm animals and when evaluating the sexual performance of males to be used in a breeding program. Please enable it to take advantage of the complete set of features!
