Kieran FitzGerald from DeLaval UK and Patrik Boner, a Swedish dairy farmer describe how the HerdNavigator technology can analyse a small sample of milk for LDH and alert the farmer of sub-clinical and clinical mastitis. Richard Shepherd from Hilltop farm in Cheshire demonstrates how the SCR technology measures rumination and how this can be used to monitor the progress of mastitis treatment.
