The Dairy Authority (TDA) blends the science of diagnostics with veterinary insight to help dairies get the data and the direction they need for informed, herd-level decision-making.
Operated by veterinarians with decades of hands-on dairy experience, TDA Labs, the laboratory arm of the company, provides advanced, standardized testing for herdhealth-impacting diseases paired with clinical interpretation. The goal is not just to deliver results, but to help producers act on them to safeguard herd health and ensure milk quality.
“Most veterinary labs are not run by veterinarians with on-farm expertise which is exactly what makes us valuable.” says Greg Goodell, owner and veterinarian of TDA Labs. “When clinical insight is needed, it’s built in.”
In addition to lab insights, TDA supports farms through bilingual online training and human resources tools. It helps clients follow best practices in milk sampling and antibiotic use, strengthening compliance and productivity.
Serving Diverse Clients through Tailored, Bilingual Support
TDA serves small family farms with 50 cows to large dairies housing up to 20,000 animals, across the United States. Regardless of the size of the farm or where the samples originate, accuracy of the result is maintained at the central laboratory in Greeley, Colorado. The lab follows strict protocols to preserve integrity and deliver consistent results.
The same commitment to quality and reliability extends across all of TDA’s testing services. The lab offers advanced bacteriology, PCR testing for diseases like mastitis and Johne’s, and chemical blood analysis to detect metabolic issues such as hypocalcemia. It also helps contain contagious diseases such as bovine viral diarrhea and Johne’s disease, protecting long-term herd stability and reducing economic disruptions for producers.
To enhance herd health management, TDA has developed tools that track disease prevalence and generate detailed monthly reports for producers. These tools enable farms to monitor risks and intervene before issues escalate. For example, when a large dairy faces a severe mycoplasma outbreak, TDA can identify infected cows and guided targeted control strategies to stop the spread and eliminate the disease.
These efforts extend well beyond Colorado, where the central laboratory is based. While it provides surgeries and hands-on treatments for nearby clients, they take on a consulting role when working with out-of-state producers. In this advisory role, veterinarians collaborate closely with on-site herd vets, nutritionists and farm consultants to evaluate herd health, develop disease control strategies and enhance overall performance.
Alongside clinical support, TDA aids in making economic decisions by analyzing production and financial data. This integrated approach defines its full-service model, which includes certified labs for feed analysis and Dairy Herd Improvement Association (DHIA) testing. Its experts also support milk processors, helping them meet food safety and regulatory compliance needs. Holding FDA certifications for regulatory milk testing, it serves clients who need official compliance without veterinary involvement.
Supporting this comprehensive service model is a collaborative team of seasoned field veterinarians supported by newer members trained through hands-on shadowing. TDA’s Spanish-speaking veterinarians have the ability to work directly with Hispanic employees on the dairy, while English-speaking vets engage with owners and management. This bilingual, team-based approach ensures clear communication across all levels of the operation, especially with the frontline staff who often have the most direct, on-the-ground insight.
Combining veterinary skill with innovative testing, The Dairy Authority supports farms in achieving healthier herds and stronger performance. With a focus on learning, collaboration and customized strategies, it remains a trusted ally for dairies aiming to elevate herd health and operational success.
