Abstract: The purpose of this study was to determine the relationship between the frequency of male-male mounting of young rams in all-male groups and their subsequent preferences for female vs. male sexual partners. Mount interactions were monitored in the home pen of 29 rams reared in 1984 and 25 rams reared in 1985. At ? 8?10 months of age, and prior to copulatory experience, individual rams were simultaneously exposed to two unfamiliar estrous ewes and two unfamiliar rams. The four stimulus animals were restrained and cloth covers were placed over their perinea to prevent copulations. The Binomial Test was used to verify sexual preferences. Of the 44 rams that were sexually active in the sexual performance tests, 30 (68.2%) met the criterion for female preference, 4 (9.1%) preferred males and 10 (22.7%) exhibited no preference (i.e., were bisexual in orientation). There was little relationship between the frequency of male-male mounting by rams in all-male rearing groups and their subsequent sexual preferences. The majority of young rams prefer to mount ewes, even prior to copulatory experience, but in the absence of females will often mount other males. |
