چکیده انگلیسی
The purpose of this study was to investigate the range of circumstances under which the “audience effect” is expressed in rams, in particular, whether the dominance-subordinate relationship and familiarity of an audience male, influences young rams' libido and semen characteristics. To achieve this objective, semen from ten 10-month Katahdin rams was collected weekly in a vaginal collection vial, while the rams were exposed individually in each session to a dominant (familiar and unfamiliar) or subordinate (familiar and unfamiliar) male, or to no audience. Reaction time, semen volume, and sperm concentration were found to be similar (P > 0.05) in rams that were alone or in those that were being observed by an audience, regardless of the dominance-subordinate relationship or familiarity of the observer. The results of this experiment support the view that the presence and dominance-subordinate relationship of an audience regardless of their familiarity with the subject is irrelevant regarding the reaction time, semen volume, and sperm concentration of ram lambs during semen collection.
