Yaks?
What about these guys?
en.wikipedia.org/wiki/Highland_cattle
Thanks. I seriously considered highland cattle, but a neighbor lost one during winter a few years ago. It appears that they’re not ready for, say, -30 F, with 80+ mph winds. And there are sometimes problems with calving. Also, local government recently confiscated nearly 400 head of cattle from the last real rancher in the area (false allegations of animal neglect from English saddle type ranchers, HOA queens, retired, pensioned NIMBYs, real estate interests, all).
Yaks should fit the weather, altitude and low growth here rather well, along with consuming far less hay. And they’re too mean for animal control chicks to mess with. ;-) There’s also some demand for high priced yak meat from restaurants frequented mostly by bipartisan socialists (nearly all restaurants these days).
My experience is with cattle in the Midwest, but quite a few things are different about Germany here...er, I mean the Rockies. The California/New York social and political environment is another problem to work around with measures like meaner livestock, better fences, camera security with auto-uploads to remote servers, lawyers, ditching the neighborly, sociable attitude from the Midwest, etc.
