CST opened in 2005 in response to research conducted by BVDV expert, Dr. Bill Hessman, et al.  This research, published in the American Journal Veterinary Research (2009), provides significant evidence that BVD-PI testing improves health and performance. Central States Testing provides BVD individual sample ACE tests (Antigen Capture ELISA) for all sectors of the cattle industry. Since 2005, CST has earned the respect and trust of cattle producers, veterinarians, pharmaceutical companies and researchers because of our dedication to the development of diagnostics and strategies used to increase profitability of beef and dairy producers.  We have been actively involved in research from both a diagnostic and production standpoint.

As advocates for the health and well-being of cattle, CST remains committed to utilizing the best and most accurate techniques for identifying sources from which BVD exposure occurs.  Controlling BVD exposure is the most effective way of eliminating the devastation that it can have on cattle health.  Eliminate the risk of BVD-PI animals by testing and removing.

Our Story

Dr. Bill Hessman has been practicing veterinary medicine, with a concentration on feedyard consultation, for more than 30 years. He has studied BVDV in Feedyard Production Systems since 2000 when research studies began in his clients feedyards. Since that time, he has become a nationally recognized expert in the field. He has conducted a number of studies with the USDA, universities and pharmaceutical companies. Dr. Hessman has also authored or co-authored multiple papers on BVDV and has presented his findings in national and international venues. One of these publications Evaluation of economic effects and the health and performance of the general cattle population after exposure to cattle persistently infected with bovine viral diarrhea virus in the starter feedlot, also known as the Cattle Empire Study, was recognized by the American College Veterinary Internal Medicine as one of the top ten research articles published in 2009.  In 2005, Dr. Hessman and his wife, Debra, co-founded Central States Testing, a laboratory specializing in BVDV infection identification. Central States Testing provides Dr. Hessman the ability to use his unique understanding of BVDV to develop the most current BVDV testing protocols in the country.
