2020 Wool Testing Information

With the expected closure of Yocom-McColl Testing Lab, 2020 will be a year of transition for wool testing in the United States. Texas A&M AgriLife is currently in the process of creating and operating a commercial wool testing lab. However, this lab will not be ready for the 2020 spring season and, thus, testing may be done through the New Zealand Wool Testing Authority (NZWTA) Laboratory. The links below provide additional information on commercial wool testing for 2020.
