Federal funding for Johne’s Disease programs has been in decline for a number of years, resulting in states receiving little to no federal money to support their programs. The disease, however, is not gone.

An article in the November 2012 Penn State Dairy Digest addresses important management factors that can reduce a calf's exposure to the bacteria that causes Johne’s Disease, including:

  • How to reduce exposure of calves to manure in the calving area.
  • Feeding management of newborn and pre-weaned calves.
  • Testing of cows using milk, blood, or manure MAP tests (Mycobacterium avium ssp. tuberculosis, a.k.a MAP).

The article was written by Ernest Hovingh, Penn State Extension veterinarian, and Dave Wolfgang, senior research associate.
