Tag and test
Tag and test is a service available for BVD testing in cattle from Nordic Star and NML. An ear tag is inserted into the ear of animals of ANY age (even from birth). On insertion, the tag cuts a disc of tissue and seals it into a small tube which disconnects after the event. Both tube and tag display an identification number.

The tube can be posted to our Hillington lab at the following address:
National Milk Laboratories plc
32 Kelvin Avenue
Hillington Park
