Texas DHIA is a  producer-controlled cooperative association aimed at helping dairies across the state continue to progress and advance their herds.  In 1967, our company began as the Texas Federation of Dairy Herd Improvement Associations, Inc. The idea began at Texas A&M University in College Station.  The company was renamed to the Texas Dairy Herd Improvement Association, Inc. in 1975.  After several years of success with the Texas A&M Extension system, the Texas DHIA moved to Stephenville. We continue to have a strong working relationship with Tarleton State University at our Stephenville location.  Our main office and lab moved to the West Texas A&M University campus in 2004. In Canyon, we are able to work with the college resources to service the large dairies in the Texas Panhandle and surrounding areas.  Currently we serve the tri-state area of Texas, Oklahoma, and New Mexico.

What We Do
​We test milk samples for various components for producers just like you.  Our certified field service technicians come to your dairy, collect samples, and gather milk weights in the barn.  The samples are then taken to one of our two lab locations to be analyzed for the components chosen by the producer.  We offer full component testing, ketosis analysis for fresh cows, and MUN (milk urea nitrogen) at both of our laboratory locations.  Our Canyon laboratory also tests for milk and serum pregnancy and Johne's disease.  To learn more about our company and what we can do for you, contact us at (806) 651-8750.
