| Trich ear tag requirements |
|
The trich year is defined as Sept 1- August 31, so application of the appropriate tag will change each year on September 1.
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 or 5-digit number.
Tags 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. 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 or 5-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, EID or a silver alphanumeric USDA tag. The tag color will cycle again every 6 years so unused tags may be saved for later use with an appropriate button.

The testing/tagging of bulls for trichomoniasis should be reported on the lab submission 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. Pooled qPCR testing is available at the ODA lab. If any pool is found positive, all samples from that herd will be re-run as indiividual qPCR tests and billed accordingly. Any subsequent testing in a positive herd will be run as individual qPCR until the provisions of OAR 603-011-0620 (7) are met. Send samples and forms to:
ODA, Animal Health Lab
635 Capitol St NE
Salem, OR 97301
Ph. 503-986-4686
Questions about the Oregon Trichomoniasis Test Positive Response Program or requests for forms may be addressed to the state veterinarian’s office, 503-986-4680.
