"In Oregon, 607.261 prescribes that no person will allow an animal to run on the open range other than a purebred bull of the recognized beef breed. Female breeding cattle are not allowed on the open range unless accompanied by one purebred bull of a recognized beef breed for every twenty-five females.[8]

To make matters worse, no stallion or jackass, 18 months old or older, is permitted to run on the open range from April 1st to October 3rd of each year.[9] (I'll leave others to comment on this.)

No ram shall be permitted to run at large on the open range from July 2nd through October 31st.[10]

So at least in Oregon, subrogation personnel have to be aware of not only the sex of the cattle which is struck by the insured, but also its age, the number of females it is accompanied by, and the time of year."

Also, it's not clear whether open range applies only to cattle on highways with motor vehicles, or includes railroads. It's not like a train can be expected to stop in a couple hundred feet.
