| Trich ear tag requirements |
|
Oregon’s Bovine Trichomoniasis Test Positive Response Program was enhanced beginning Sept. 2005 with a mandatory ear tag requirement for all bulls tested for trichomoniasis. The official Oregon Trich Ear Tag must be tamperproof, 3” wide x 2 1/4” tall with a self piercing male button printed with the current trich year. The female portion of the tag will have OR TRICH printed above a 4 digit number.
The trich year is defined as Sept 1- August 31, so application of the appropriate tag will change each year on September 1. For example, beginning September 1, 2006, the appropriate tag for bulls tested from that date through August 31, 2007 will be WHITE, indicate 2007 on the button, and have a 4 digit number on the face.
Tags (7500) meeting the identification requirement are in stock at MWI Veterinary Supply (1-800-824-3703, specify TRICH TAG OREGON) and available for immediate shipment. The tags come in bags of 25 at a cost of $24 per bag. Due to the very specific nature of these tags, they are non returnable to the supplier. Any other tag manufacturer’s product may be special ordered providing it fits the above specificity with respect to tag size, layout, and color. Special orders will need to specify their 4 digit number sequence. Please allow approximately 2 weeks for the special order process.
Tag colors will change on September 1 of each trich year according to the chart below. Previous year trich tags should be removed and replaced with the tag consistent with the current year’s test. Continuity of identification of the bull from year to year should be maintained either by a ranch tag, tattoo, or a silver alphanumeric ID tag. The tag color will cycle again every 6 years so unused tags may be saved for later use with an appropriate button.
| Trich Year | Test Period | Tag Color | | 2006 | Sept 1, 2005-August 31, 2006 | Blue | | 2007 | Sept 1, 2006-August 31, 2007 | White | | 2008 | Sept 1, 2007-August 31, 2008 | Yellow | | 2009 | Sept 1, 2008-August 31, 2009 | Blue | | 2010 | Sept 1, 2009-August 31, 2010 | Red |
The testing/tagging of bulls for trichomoniasis should be reported on the OR STATE TESTING/TAGGING FORM which also requests age, breed, and description information. The rules allow for tagging of virgin bulls without a test providing the owner’s signature is on the form in the appropriate top right box. Please note the definition of virgin bull in the rule. Send or fax the test forms to:
Julie Weikel, DVM

(c) Require permanent identification and testing of all bulls, excepting virgin bulls, in the test-positive herd and exposed herds.
(5) All bulls in herds required to be tested must be withdrawn from breeding contact and tested between 10 and 90 days after withdrawal.
(6) All bulls in test-positive herds must each have two (three are recommended) consecutive negative test results with each test event separated by at least seven days, after initial diagnosis is made. Bulls that have a positive test result shall be considered infected and be handled as described in 603-011-0620(8).
(7) All bulls from a test-positive herd must be re-tested every trich-year until every remaining bull tests negative during the same test period.
(a) All bulls from a test-positive herd must be re-tested before February 1 of the following year.
(b) All bulls removed or culled from a test-positive herd are to be tested before removal or culling.
(8) Test-positive bulls shall be held under quarantine separate and apart from other cattle or shall comply with one of the following:
(a) Test-positive bulls may be retested and, if found negative on three consecutive tests that are separated by at least seven days, may be considered test-negative and released from quarantine; or

(10) The Department may waive the mandatory testing and quarantine provisions of this rule if:
(a) The owner or manager demonstrates that a herd program for control of bovine trichomoniasis which the Department determines, after consultation with the Advisory Panel, to be adequate under the circumstances, is in place and operational at time of diagnosis; or
(b) The owners or managers of the test positive herd and of all exposed herds agree to not test, or agree to pursue a control program of their own design, and the Department determines that such action is adequate under the circumstances.
