Prevention of Bovine Trichomoniasis
SD – South Dakota State Veterinarian Dr.
Dustin Oedekoven reminds cattle producers to comply with animal health
regulations to prevent the introduction and spread of bovine trichomoniasis.
Trichomonas foetus is a reproductive disease
of cattle. It is transmitted between cows and bulls during breeding, and
can result in early term abortions. Producers are often unaware of the disease
until it 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.
Cattle producers can take steps to help
prevent their herds from becoming infected. Consult your herd veterinarian to
assess the risk to your herd, and evaluate testing options and management
strategies that will aid in early detection and prevention. Only purchase and use
virgin bulls for 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
In cooperation with the cattle industry the
South Dakota Animal Industry Board has implemented rules in an effort to help
prevent trichomoniasis in cattle:
bulls must be tested negative for trichomoniasis prior to being sold,
loaned or leased in South Dakota for breeding purposes;
2. Any non-virgin bull
entering South Dakota must be tested negative for trichomoniasis;
non-virgin and non-pregnant female cattle may be imported, loaned, leased nor
acquired for breeding purposes in South Dakota.
cattle being imported must have a Certificate of Veterinary Inspection with
individual official ID’s listed and an import permit from the Animal Industry
Cattle producers with concerns about trichomoniasis should
contact their herd veterinarian or the South Dakota Animal Industry Board at
