Effective Jan. 1, new Designated Surveillance Area (DSA) testing requirements will apply to all sexually intact female cattle and bison 12 months of age and over.
At their meeting on Sept. 15, Wyoming Livestock Board (WLSB) members voted to change the age requirement for test eligible animals from 18 months to 12 months of age. The revised rules were signed by Governor Mead on Monday, Oct. 31 and will go into effect Jan. 1.
According to the WLSB’s recently-revised Chapter 2 Rules, all sexually intact female cattle and bison 12 months of age and over must have a negative brucellosis test within 30 days prior to moving or changing ownership between the dates of Feb. 1 thru July 31. Between Aug. 1 and Jan. 31, any negative test performed during that time period is valid from the time of the test until the end of that time period (Jan. 31).
The rules further clarify the testing age by stating, “Heifers born during the previous calendar year and shipped after August 1 of their yearling year shall be tested for Brucellosis…”
A copy of the revised Chapter 2 Rules can be obtained through the Wyoming Secretary of State’s website at https://rules.wyo.gov/.
