Board acts to reduce threat of livestock disease

BISMARCK – The State Board of Animal Health has revised its importation order regarding bovine trichomoniasis in an effort to reduce the threat of the disease to North Dakota livestock.

“The order now applies to open (non-pregnant) cows that may be a source of trichomoniasis introduction into herds in North Dakota,” said Dr. Susan Keller, the state veterinarian. “At this time, the order only applies to cattle moving into the state and not to intrastate movements.”    

The revised order now includes the statement: “No non-virgin and non-pregnant female cattle may be imported for breeding purposes into North Dakota.” Previously, the order affected only bulls.

Keller said exemptions may be made for virgin and non-pregnant cows registered with a breed registry or to be used in confined dairy operations or for embryo transplant operations.

The complete order can be found at www.nd.gov/ndda/orders/board-order-2007-03-trichomonas-foetus-testing-imported-bulls-revised-6-15-2012.

A venereal disease of cattle, trichomoniasis can cause early pregnancy loss, abortion and infection of the reproductive system. The cause is a protozoan parasite, Tritrichomonas foetus, transmitted from infected bulls to heifers or cows. Trichomoniasis is a major cause of infertility in naturally bred cattle in many countries around the world.
