Extra-sensitive lab test results dispel industry’s urea residue concerns
Teagasc tests reveal that residues were not found in bulk tank or individual cow milk samples. File Picture.
Industry concerns around potential for protected urea residues in milk have been eased by results of Teagasc tests which are 25 times more sensitive than previous tests.
A highly sensitive and validated method for detecting urease inhibitor NBPT and NBPTo in milk was developed at Teagasc, Ashtown, and used to test milk from the Teagasc, Johnstown dairy herd, where protected urea is used.
