Brief Description

The Dairy Laboratory provides service for analysis of milk components in support of the Genetic Improvement Program of PCC. Service is mainly for dairy herds that are participating in milk recording and performance testing including PCC assisted cooperatives, among others. Milk samples are rapidly analyzed for milk fat percentage, milk protein percentage, lactose, total solids, and somatic cell count (SCC). The facility is presently available at the PCC National Headquarters.

Service Standard

Under normal circumstances, the analysis is completed within nine working days from the date or request or submission of milk samples. Raw milk samples can be preserved up to 7 days at 4oC-5oC, if bronopol is added. If milk sample is unpreserved (no added bronopol), place the sample in a container with ice then immediately submit to the laboratory for analysis the soonest time possible (within 2 days). Unpreserved samples maybe analyzed up to 72 hours after initial collection of milk samples. Prospective clients should fi rst make arrangement with milk laboratory personnel before submission of samples for orientation/training on proper milk sampling, handling, and storage scheduling.
