I don't raise cattle, but I know a lot of people who do.
The general rule of thumb is that it takes about a 100 cows to
sorta support a family. Look at the math. Depending on the price, a hundred market steers/calves might bring $600-$1000 each. So that's $60K-$100K per year
gross - minus of course, calving losses, losses to predators, feed supplements, inoculations, buying or raising hay for winter feed, maintaining fences and other infrastructure, land taxes, cost of pickups, atv's, and/or horses to work with the cattle, plus whatever else the farmopoly of life throws at you (floods, drought, lightning, rustlers, etc).
I'm guessing you might be really lucky to clear $30K on a good year, in return for working most of 365 days of the year. Plus side is you get to write off the 1950's house you live in.
Out here, to run that 100 cow/calf pairs you need about 40 acres per pair or 4000 acres (almost 7 sections or square miles), plus land to grow your own hay and room for house, corrals, hay barns, equipment barns, bull pasture, horse pasture, etc. Since I don't do it myself I'm probably leaving out a lot of stuff that you need.
And this is all rough, rocky, and rolling range land (except maybe for the tiny percentage that is irrigated hay meadow) that can't be put to any other production except for deer, antelope, rabbits, and a few scrubby pine trees.
So - tell me again how this isn't intended to shut down every dairy farmer and beef rancher in the USA ...?
