Laboratory Services
Our in-house milk quality laboratory utilizes procedures standardized by the University of Minnesota and the National Mastitis Council. Quarterly, we participate in Cornell University's laboratory proficiency test.
Before submitting samples for the first time, please call our office for detailed instructions on sample collection, labeling, and handling.
Culturing Clinical Mastitis:
- Why culture? Click here...
- Our goal for individual cultures of quarters with clinical mastitis is to provide rapid results for use in culture-based treatment. We determine the organism causing the infection and report results for use in selecting treatment.
- Preliminary results can be reported at 24 hours after plating, if desired. Final results will be reported at approximately 48 hours.
- Results can be reported by a variety of options: phone, email, fax, or Google Drive.
- Individual cow milk samples that cannot be delivered to our office within 12 hours of collection should be frozen.
- For samples arriving within 12 hours, only refrigeration is necessary.
- In order for samples to be plated on the same day they are submitted to our office, frozen samples should arrive by 2:00 pm and refrigerated samples by 3:00 pm.
- Samples received later are usually not plated until the following morning.
Other Lab Services
- In addition to our milk quality lab services, we also offer other in-house lab tests related to animal health, cultures, drug residue testing, and more. See below for these services.
