title: Libido and semen characteristics of Murrah, Surti, and local buffalo bulls in Sri Lanka.
abstract: The sperm properties and the libido were investigated in four Murrahs, three Surtis, and one local buffalo over a period of four months. As regards their libido, no specific features were found for the different breeds. The volume of the ejaculates and the concentration of the sperms were highest in the Murrah buffaloes, but they also exhibited the highest proportion of dead sperms in the first ejaculate. The local buffalo bull had a greater ejaculate than the Surti bulls but its sperm concentration was smaller and the proportion of dead and/or abnormal sperms was higher. Comparing the first and the second ejaculate, significant differences were found as regards the proportion of dead sperms and the motility in Murrah bulls, the sperm concentration and the proportion of dead sperms in Surti bulls, and proportion of abnormal sperms in the local buffalo bull.
