Bighorns Killed after Contacting Domestic Sheep

Because bighorn sheep are susceptible to diseases that can be carried by domestic sheep and goats, the Department’s 2010 Bighorn Sheep Management Plan provides direction that Fish and Game remove bighorns in a timely manner when they come in contact with domestic herds to prevent potential transmission of disease to other bighorn sheep, the release said.

Domestic sheep and goats often carry pathogens that wild sheep may be susceptible to and that can result in fatal pneumonia or other diseases, the release said. The greatest risk occurs when a wild sheep mixes with domestic sheep or goats and then returns to a wild herd, potentially spreading the pathogens. In some cases, this can result in large-scale die-offs in wild sheep.

The bighorn rams were killed to prevent risk of them returning to their herds and potentially infecting other bighorns, the release said. The domestic sheep are also being tested…(CONTINUED)
