Cattle owners should test herds for trichomoniasis

RBC I The Colorado Department of Agriculture reminds cattle owners to test their herds for Bovine Trichomoniasis. As of Dec. 25, there is one positive trich location in Park County.
Throughout 2013, there have been 10 trich cases in six counties: Park, La Plata, Costilla, Las Animas, Otero and Archuleta.

“Testing and monitoring herds for trichomoniasis is the best method of controlling this infection,” said Dr. Keith Roehr, state veterinarian. “Cattle owners should talk to their veterinarian to determine the best management practices for their herd.”
“Trich” is a costly, yet preventable, infection that can affect dairy and beef cattle. If bulls become infected, the percentage of open cows can increase from 5 to 30 percent.
Trich is a venereal disease of cattle caused by Trichomonas foetus (T. Foetus). The T. foetus infection causes fertility problems, such as early embryonic death or abortion of the calf and is asymptomatic in bulls.
Colorado trich regulations require all non-virgin bulls changing ownership or being transported into Colorado be tested for T. foetus unless the animal is going to slaughter. Bulls on public land grazing permits or with grazing associations must also be tested prior to turn-out.
Several diagnostic laboratories across the state offer trich testing; samples must be taken by an accredited veterinarian and results will be available after four to six days.
