What are Most Common Diseases Affecting Mule Deer?

Common Diseases Affecting Mule Deer in Montana

Chronic wasting disease (CWD) is a significant concern for mule deer in Montana. It’s a neurological disorder that affects deer, elk, and moose, causing weight loss, behavioral changes, and eventually death. According to the Montana Fish, Wildlife, and Parks Department, CWD has been detected in 23 of Montana’s 56 hunting districts. CWD can be managed through hunting regulations, such as allowing only antlerless deer harvest in affected areas.

Brucellosis and Bovine Tuberculosis

Brucellosis is another disease affecting mule deer in Montana. It’s a bacterial infection that can cause reproductive problems, abortion, and death. Bovine tuberculosis is also a concern, as it can be transmitted from cattle to deer. These diseases can be managed through vaccination programs, testing, and hunting regulations. Hunters can play a crucial role in helping to detect and manage these diseases by submitting deer heads for testing.

Other Diseases Affecting Mule Deer

In addition to CWD, brucellosis, and bovine tuberculosis, other diseases affecting mule deer in Montana include epizootic hemorrhagic disease, bluetongue, and pneumonia. Epizootic hemorrhagic disease is a viral disease that can cause high mortality rates in deer. Bluetongue is another viral disease that affects deer and can cause significant mortality. Pneumonia is a common disease in deer, particularly in young or old animals. Hunters can help manage these diseases by reporting sick or dead deer to the Montana Fish, Wildlife, and Parks Department.
