Texas, Louisiana, and Arkansas are the latest states to publish regulations dealing with trichomoniasis or "trich" as it is commonly called. That leaves Kansas as the only western state with no trichomoniasis regulations on the books, at least for now.
Bovine trichomoniasis is a sexually transmitted disease caused by long-lasting protozoan parasites that live in the penile crypts of bulls and the reproductive tract of infected cows. Bulls are the long-term carrier of the protozoan parasite, show no signs of infection or visible lesions and can shed the organism indefinitely. The majority of infected cows will clear the infection if given 120 to 150 days of sexual rest.
There is no way to tell if a herd is free of the infection until it is tested. There is no treatment for trichomoniasis infection.
