More: "Under the rule, any wolf that has killed three cows or calves in one year must be "removed" -- shot or placed in captivity indefinitely. Wolves killed 22 cows and calves in 2007, according to Fish and Wildlife.

Policies such as these have created a revolving door that shuttles wolves from holding pens to the wild and back again, hampering adaptation, breeding and pack dynamics.

Those results run counter to the intentions of a captive-breeding program, which ideally should leave wolves able to fend for themselves in the wild without human assistance."

Another reason why they should really do more research before they throw the wolves to the cattle.
