COLORADO SPRINGS,
CO— Beef producers who have culled one or more animals for unresponsive chronic
diarrhea combined with reduced milk production and thin condition might want
to learn more about Johne’s disease—and find out if their herds are infected
with Johne’s disease. A good source of information about Johne’s disease
is a recently released 16-page brochure that is free to beef producers and
veterinarians.
The new brochure describes how animals become infected with the organism
that causes Johne’s disease, details measures producers can take to help
prevent and control Johne’s disease and explains herd testing strategies.
The brochure, which is underwritten by USDA-APHIS-VS and produced by the
National Johne’s Education Initiative overseen by the National Institute
for Animal Agriculture, is science based and written in producer language.
“Johne’s disease is a slow and progressive bacterial disease of the intestinal
tract that affects ruminants and is caused by the bacterium Mycobaterium
avium paratuberculosis,” states Dr. Micheal Carter, National Johne’s Disease
Control Program Coordinator, National Center for Animal Health Programs,
USDA-APHIS-VS. “It causes significant economic loss for producers whose animals
have the disease, and the goal of every producer should be to prevent getting
it on their farm if they don’t have it or control the disease to reduce the
economic impact in herds with the disease.”
Johne’s disease is estimated to be present in eight out of 100 U.S. beef
herds. Beef cows clinically infected with Johne’s disease produce less milk
resulting in lighter calves at weaning, and infected cows can be slower to
breed back.
Johne’s experts agree that the incidence of Johne’s in beef herds can be
reduced significantly when producers know about Johne’s disease and implement
measures—including testing—to control the disease-causing organism.
