FOR IMMEDIATE RELEASE: Bovine Trichomoniasis
PIERRE, SD – A reproductive
disease of cattle that can be economically devastating for ranchers has been
diagnosed in another South Dakota cattle herd. Bovine trichomoniasis, or trich,
has recently been diagnosed in a bull that was leased to a ranch with pastures
in Gregory and Mellette counties.
The State Veterinarian’s Office
is encouraging producers in the area to talk with their veterinarian about
Trichomonas foetus is
transmitted between cows and bulls during breeding, and can result in early
term abortions. Producers are often unaware of the problem until the disease is
well established in the herd. Signs that the disease may be present in a herd
include a high number of open cows, cows showing signs of heat when they should
be pregnant, and the presence of many late-calving cows.
Producers can take precautions
to help prevent their herd from becoming infected. First, only purchase and use
virgin bulls for breeding. If non-virgin bulls are purchased, they must be
tested negative for Trichomonas foetus prior to breeding. Timely pregnancy
testing of females and prompt removal of open cows to be sold for feeding and
slaughter will also decrease the risk of disease spread. Finally, maintain good
border fencing to help keep livestock in their respective pastures and avoid
unintentional commingling of animals.
In cooperation with the cattle
industry the South Dakota Animal Industry Board has implemented rules in an
effort to help prevent trichomoniasis in cattle:
Non-virgin bulls must be tested negative for trichomoniasis prior to being
sold, loaned or leased in South Dakota for breeding purposes;
Any non-virgin bull entering South Dakota must be tested negative for
3. No non-virgin and non-pregnant
female cattle may be imported, loaned, leased nor acquired for breeding
purposes in South Dakota.
Cattle producers with
concerns about trichomoniasis should contact their herd veterinarian or the
South Dakota Animal Industry Board at 605-773-3321.
