One yellow card in milk monitoring

Only one yellow card was issued and no red card was produced in the 2011 monitoring of Irish milk recording laboratories which is carried out annually by the Teagasc Moorepark National Dairy Research Laboratory.

A yellow card indicates that tolerance limits were exceeded more than four times in the year for measurement of fat, protein, lactose, and SCC in the samples which Teagasc Moorepark sends each month to the four milk recording labs (at Munster AI’s two labs, Progressive Genetics, and Tipperary Co-op).

Results of the inter laboratory proficiency testing were given at the recent International Committee for Animal Recording conference in Cork, but the identity of the “yellow-carded” lab was not divulged. It had test results outside tolerance six times, five of which were for SCC. Of the other three labs, most of their test failures were for fat and protein measurement.

One had only one test result outside tolerance. Another had two. The third had three outside tolerance, plus one result more than two times outside tolerance. The tolerances are 0.1% for fat or lactose; 0.07% for protein, and 15% for SCC. There were 222 tests.
