PENA JOYA, Miguel A; GONGORA, Agustín  y  JIMENEZ, Claudia. Infectious agents affecting fertility of bulls, and transmission risk through semen: Retrospective analysis of their sanitary status in Colombia. Rev Colom Cienc Pecua [online]. 2011, vol.24, n.4, pp.623-633. ISSN 0120-0690.

The most important infectious diseases that affect fertility of the bull, and their transmission via semen are reviewed in this article. Additionally, a retrospective analysis of the diseases reported in Colombia was also addressed. In general, there is high seropositivity for IBR and BVD, two diseases that can be transmitted by semen due to viral latency and persistence, and lack official control programs in Colombia. It is necessary to move forward with the support of livestock associations and animal health institutions in order to establish true artificial Insemination centers that allow a permanent surveillance of donor´s health status, and the production of pathogen-free semen as a way to control transmission of diseases via semen.

Palabras clave : bull; Colombia; fertility; infectious agents.
