What is "Trich"?
Cattle trichomoniasis or "Trich" is a venereal disease of cattle caused by the Tritrichomonas foetus protozoa, which is about the size of a sperm. Infected bulls carry the organism on their penis and prepuce. Trichomoniasis is then transmitted to cows through breeding. Cows may abort early in the pregnancy and become temporarily infertile. Only testing will confirm the presence or absence of the disease.
Cattle producers can lose valuable income from the extended breeding seasons and diminished calf crops caused by this disease. The cattle industry and trade associations in Texas requested that the Texas Animal Health Commission develop regulations to stop the introduction and spread of this disease.
TAHC’s Trichomoniasis regulations were developed with a working group of producers, market operators, veterinarians, laboratory representatives and educators. Under the program that was phased in beginning April 2009, Trichomoniasis is a reportable disease in Texas. The program will be reviewed annually by the Trichomoniasis Review Working Group.

For more information or questions about the Trichomoniasis Program, please contact your local TAHC Region Office.
