Yearling beef bulls, representing different Bos indicus and Bos taurus breeds, were given two sexual performance assessment (libido score, number of services, time to first mount and time of sexual inactivity) at four test periods (January, April, July and October) in 1991 (Trial 1) and 1992 (Trial 2) at the Subtropical Agricultural Research Station, Brooksville, Florida, Breed and test period, as well as their interactions, influenced most results. Sexual performance assessment generrally improved with age in Boss taurus breeds, but not in Bos indicus. The temeprate Bos Taurus breeds (Angus and Hereford) were most sexually active, the tropically adapted Bos taurus breeds (Senepol and Romosinuano) intermediate and the two Bos indicus breeds (Brahman and Nellore x Brahman) were least active. Service rates were generally low. Seasonal patterns in sexual performance were not apparent, with breed and year differences occurring. Although breeds showed consistent test results, the failure of Bos indicus bulls to service in any test, indicates either sexual immaturity or inadequate procedures for assessment of sexual performance in this brred group. |
