Reply #11: You might look into Scottish Highland cattle. They supposedly thrive on forage.

They are relatively docile (there are more than a few stories of Bulls coming over for a nice brushing), self defensive with predators, need little or no shelter, do well in a variety of climates, birth very easily and produce a very high quality and healthy low fat beef.

They are useful, according to some, for brush clearing and pasture restoration. They use their horns to knock over the brush for easy access. They are also very disease resistant.

I personally think they are incredible looking animals.
