LOGAN, Utah — Ranchers are invited to bring their beef bulls to the USU corrals at 1200 West and 1500 North in Logan to have them semen and trichomoniasis tested by Dr. David Moss and Hoffman AI.
This annual event will take place on Monday and will be repeated two weeks later on March 26. Testing will begin at 9 a.m. and end by 2 p.m. Cost is $60 per head and is first-come, first-served.
Last year we had very few bulls come the first day, which was beautiful and pleasant. Our last day was miserable, with an abundance of snow and rain and mud. Unfortunately, most of the bulls showed up on the miserable day. It would be helpful if you contact the Extension office, 435-752-6263, or Hoffman AI, 435-753-7883, so we have an idea of the number of bulls to be tested.
Trichomoniasis is a highly contagious sexually transmitted disease in cattle that results in abortions and infertility. The only way to confirm the trichomoniasis infection is by testing with a procedure approved by the Utah Department of Agriculture and Food. Utah Administrative Code outlines the details of trichomoniasis testing. All bulls 12 months of age or older, regardless of ownership or change of ownership, must be tested by an accredited veterinarian with an approved test for trichomoniasis.
This test must be performed annually, between Oct. 1 and April 30, or prior to exposure to female cattle. All bulls must be classified negative prior to exposure to female cattle or offered for sale. All Utah bulls that are tested shall be tagged in the right ear with an official trich tag by the certified veterinarian performing the test. Bulls which bear a current trich tag from another state will be acceptable to the state of Utah providing they meet all Utah regulations. Bulls kept in confinement operations, going direct to slaughter or to a qualified feedlot are exempt. Rodeo bulls and bulls attending livestock shows are also exempt, unless they have access to grazing and are exposed to female cattle.
The disease is spread throughout the herd when infected bulls mate with multiple cows. Infected bulls and cows typically act and look normal. Usually, cattle producers become aware of a problem when cows are pregnancy-checked and there are too many open cows, a prolonged calving period, or noticeably reduced calf crop. Abortion or re-absorption of the fetus usually occurs early in pregnancy and cows become temporarily infertile. Late-term abortions have been reported, but are not common.
Obviously ranchers have additional options available as we have other accredited veterinarians in the valley that can perform the same tests. The important thing is that bulls be tested before breeding season begins. If any “cowboys” want to help move bulls through the pens on the days we are testing, call 435-752-6263, and we’ll be happy to have your help.
