Milk Microbiology

Milk Microbiology is one of the most important things we do. We utilize highly skilled technicians and state-of-the-art instruments to achieve accurate results and speedy turnaround time.

Certified DHIA

We are a certified DHIA Field tester and lab service. We customize an on-farm testing program for each dairy and set up a testing schedule to suit the dairy's needs. We analyze much more than SCC, fat, and protein. We can also check milk for lactose, fatty acids, and BHB (beta-hydroxybutyrate).

Wide Variety of Testing

We are a professional laboratory that does more than simple cultures. We offer a wide array of tests that are dairy focused as well as tests for other species.
