Girl friend said the same, they did have pigs and cows but they were farmers due to the crops. I did not get there were crops in this article. It sounded more like they were in the ranching business to me and have never heard livestock folks call themselves farmers.
AFAIK, most ranch cattle are sent to FARM feedlots to fatten up before slaughter.
If you have strictly graze land like your have our west, you can call yourself a rancher.
It also takes alot of ranchland to raise a single head. Something like 20-50 acres per year, depending on water, grass.
In Tennessee we can raise over two hundred cows on a five hundred acre farm that has plenty of woods and crop land. On something around two hundred acres. We get plenty of rain, good siol and warm weather and put up plenty of hay for the winter. This year will be tight.
