We had some Highland cattle on this ranch from before I came here in 1957, of and on until we butchered the last of a few purebred steers we bought, maybe in the '70's.
We thought the beef was the very best. Almost entirely grass fed. The last we butchered were very old, at least 7, as we were growing out the horns. And grow they did! We had several heads mounted and hides tanned for rugs.
Believing we would have to make all the meat into hamburger, at that age, we were amazed when the meat inspector at the plant said he believed it would make good steaks and roasts. And we thoroughly enjoyed that meat. It was sort of dark and not so much like venison as like mature grass feed beef. We have also butchered Longhorns of similar age and found that to be the situation with that breed, also.
Friends commented that "this tastes like REAL beef"!
Ours came from the Baxter Berry ranch at Belvidere, SD, long ago sold out of the family. He imported many Highlanders from Scotland, believing the breed to be a natural fit for his rugged Badlands ranch, and he was right. However, Denny is right that they never became 'popular' in this area. Some didn't like the long haircoat, especially in muddy feedlots! Some didn't like the 'motherly' attitude of the cows, While those from the Berry ranch may not have been really tall, they were very long and well muscled and quite heavy.
We really miss having them around.
