Although the list of diseases that can be transmitted through mating or semen is large, in this article only highlights important and commonly encountered diseases. Farmers should ensure that bulls being used in the breeding programs are free from infections transmissible through semen. These diseases are:
It is mandatory for the semen suppliers to get their bulls tested against these diseases periodically. You must ask the supplier company or your AI Technician to provide information about test results. In case you have a bull used for breeding purpose, it must be tested annually or at least every two years for the above diseases. Please note that in case of bulls these diseases may not show overt signs in early stages but when the causative organisms are transmitted to cows, complex disease syndromes might result. Most of these cause infertility, abortion or sub-fertility hence these are of huge economic importance.
Material to be collected for testing:
Brucellosis Semen sample PCR test / bacterial culture
Toxoplasmosis Serum for titter
Trichomoniasis Preputial wash for microscopic examination
Please Note: To declare a bull positive for the above diseases ensure that the tests are done at least twice 21 days apart.
