QMMS now offers individual cow milk sample testing for antibodies to Mycobacterium avium paratuberculosis (MAP), the infection which causes the clinical signs of Johnes Disease in cattle. Antibody-positive cows can be clearly marked and managed away from dry and other calving cows to aid breaking the cycle of disease transmission.

Johnes testing can be incorporated into your routine milk recording by using samples collected for cell count and compositional analysis and we often advise selective testing based on previous disease test results and age of the cow to offer a cost-effective risk management monitoring service.

Further information and specialist veterinary advice on the purpose and pitfalls of Johnes testing is available from Andrew and James.
