Venereal diseases like trichomoniasis (trich) and vibriosis (vibrio) remain common causes of reproductive failure in cow-calf herds in western Canada. Unlike trich, there is no good diagnostic test available for vibrio.
A recently-completed research project funded by the National Check-off and Canada’s Beef Science Cluster studied polymerase chain reaction (PCR) tests, which detect specific DNA sequences, as a potentially cost-effective and practical diagnostic testing strategy for identifying beef cattle with vibrio.
The research found that the PCR test is 85% accurate at identifying positive and negative bulls when sampled in the field. While not perfect, it is an improvement in what has been available to practicing veterinarians.
