Mycoplasma bovis survives surprisingly well in the environment, as well as in animal respiratory tracts. At 39 degrees F, the bacterium survives for nearly two months in sponges, more than two weeks in water, and 20 days in straw, says Fiona Maunsell,
She recommends the following:
Give facilities a break between groups of calves to help reduce pathogen load.
Always practice good hygiene.
Provide adequate ventilation.
