About Me

Dr. David Wilson is a Dairy Extension Veterinarian. He provides the dairy industry with research-based information regarding dairy animal health, primarily through a combination of disease or herd health problem investigations and applied practical research with some basic laboratory research. His major research focus has been mastitis, milk quality, and infectious diseases of dairy cattle or dairy goats.

Dr. wilson works in epidemiology by recognizing when diagnoses have been made of emerging or unusual cases of disease that may affect other animals in herds or flocks, or humans, from cases presented to the Utah Veterinary Diagnostic Laboratory (UVDL).  He follows up with the livestock producers/animal owners and make farm visits if necessary.  He publishes and otherwise communicates these results regarding unusual or emerging diseases.

He and his team have done three statewide surveillance projects of bulk tank milk from most dairy farms in Utah, testing for several important diseases.  Community outreach is statewide, regional, national, international to dairy producers, veterinarians, milk buying company personnel, and other members of the dairy industry.

Current projects:

  • Comparison of milk and blood test strips and Fossomatic automated milk analysis for beta-hydroxybutyrate levels in milk of recently calved dairy cattle. This study will compare an accepted blood measurement of beta-hydroxybutyrate (BHB), a major test used to detect negative energy balance in dairy cattle vs. that of a milk BHB test strip and that of a new method in meter-collected milk using a high throughput (Fossomatic) machine. We will also evaluate milk handling and storage condition effects on the BHB numerical results.
  • Dairy cattle disease surveillance and descriptive and statistical analyses. This project continues into its 7th year. The current phase is testing most of the dairy herds in Utah for presence of Mycoplasma spp., Johne’s disease (JD), and Bovine Viral Diarrhea virus (BVD), using 3 different test methods designed for bulk tank milk samples. We have tested for mycoplasma and JD before, developing a repeated sampling strategy and offering an outreach and disease reduction program to dairy producers whose herds tested positive. We intend to develop a new testing strategy for BVD in dairy herds using bulk tank milk samples.

Dr. Wilson's research receives funding from the Utah Agricultural Experiment Station, Utah State University extension funds, and private industry.

Dr. Wilson will be teaching epidemiology in the new USU School of Veterinary Medicine.
