Milk Testing Services

Dairy One’s state-of-the-art laboratory tests milk samples for fat, protein, somatic cell count (SCC) and milk urea nitrogen (MUN). Milk analysis is performed with Milkoscan/Fossomatic equipment. The Milkoscan uses Fourier Transform Infrared Spectroscopy (FTIR) technology for the determination of milk components. Parameters are as follows:

  • Butterfat (%)
  • True Protein (%)
  • Lactose (%)
  • Total Solids (%)
  • Milk Urea Nitrogen (MUN)
  • FPD (freezing point/cryoscope) °C
  • Casein (%) on some analyzers
  • Ketosis Screening using Beta hydroxy buterate (BHB) coming soon.

The Fossomatic uses Flow Cytometry for determination of somatic cells in milk.

Milk Components: Butterfat, Protein, Somatic Cell, Milk Urea Nitrogen
Milk Diagnostics: Milk Pregnancy, Johne’s, Leukosis

Submitting Non-DHIA Samples for Analysis

  • Ship in a cooler (s) with ice packs and temperature control, “TC”, sample. Stabilizing samples with small bubble wrap or paper is recommended as packages get jostled in transit and can arrive spilled if not supported or cushioned.
  • Ship overnight delivery to Dairy One Milk Laboratory at 720 Warren Rd, Ithaca, NY 14850.
  • Clearly label samples with correct ID.
  • Samples can be either preserved or unpreserved. Sample volume should be a minimum of 10ml or 2 oz vial filled to the etched line. 

*For testing of raw fluid bovine, ovine, and caprine milk only. For other dairy samples, see Check Mark Laboratory.

Please be sure to include a completed copy of the ML Sample Submission Form when submitting samples.
