Trichimoniasis is a venereal infection of cattle that is caused by the protozoan Tritrichomonas foetus. The protozoa colonize the reproductive tract in the cow and skin folds of the bull. Most cows will clear the infection within 95 days, but bulls over 4 years old carry the protozoan to the next breeding season. The only indication that trichimoniasis is a problem in your herd will be infertility, a high percentage of cows returning to estrus, late calving, occasional pyometras, and abortions.

It is important to closely monitor your herd, and if any signs are observed you should contact your veterinarian to determine if trichimoniasis or another disease is present. Trichimoniasis can be confirmed through culture of mucus or preputial smegma samples. In collaboration with your veterinarian a management plan consisting of vaccination of young virgin bulls, testing and culling positive bulls and sexual rest for cows can be made in the treatment and removal of infection from your herd.
