Hog cholera hits western Minnesota

Examining an ill pig

A disastrous hog cholera epidemic in 1913 threatened the swine industry in Minnesota's west central counties. Renville County Extension agent W.E. Morris helped save hog producers close to $1 million. Renville County cholera losses dropped from 56 percent in 1913 to less than 5 percent in 1914, and Minnesota set a nationwide record in controlling the disease.

Morris organized a team of swine raisers in each township to help inform their neighbors and help veterinarians. In 1923, the legislature asked Extension to set up hog cholera vaccination schools led by Extension veterinarians. The veterinarians also taught improved herd management, and by 1972 the disease had been eliminated from the state.
