A reproductive disease of cattle has been found in another South Dakota herd.
The state Animal Industry Board says bovine trichomoniasis, or trich, was recently diagnosed in a herd in Dewey County.
It's the fourth herd with the disease since last November. Veterinarians earlier diagnosed trich in two Oglala Lakota county cattle herds and one herd operating in Corson and Ziebach counties.
Trich can cause early term abortions in cattle. The board says the disease can be "economically devastating" to ranchers, and has put several rules in place to try to prevent its spread.
