Bovine trichomoniasis can be costly for cattle operations that use natural service. The disease can be found worldwide and can affect both beef and dairy cattle.

Trichomoniasis (often called “trich”) is a true venereal disease of cattle caused by a protozoan organism called Tritrichomonas foetus. It is spread through sexual contact. There are no approved treatments for infected bulls or cows.

Infected cow herds experience infertility, uterine infections (pyometras), and early abortions. Pregnancy losses occur early in gestation, resulting in repeat breeders and inconsistent calving distributions.

Trichomoniasis causes no clinical signs in the bull and does not affect sexual behavior or semen quality.

The reservoir for this organism is the persistently infected bull. The organism lives in the sheath and skin folds of the bull’s penis, and bulls more than 4 years old are more likely to be chronic carriers of the disease.
