Precisely. For example you can't grow much on the high plains of Wyoming and Montana. You are lucky if you can manage much of a kitchen garden with the short growing season. But cattle and buffalo are perfect for this region.
I saw Navajo cowboys working when I visited my brother in the southwest. Take their cattle what are they supposed to do for a living?
Anything cows can do goats do better. They also take marginal lands and scrub brush and turn it into meat, milk, leather and till the land. Goats are much more hardy than cattle they can live on less water and also are browsers in.addition to grazers they literally will east anything green including cactus chewing around the spines. There is a reason goat is the most consumed red meat on the planet they are magical in their efficiency. Goats are also the pet food of the muzzies and Latinos so the left will never EVER ban it’s consumption notice how they have never once talked about methane from goats which is also under a quarter of what a cow puts out on a lb per lb basis still the left doesn’t let a peep out about goat meat. Nubians are a great dual purpose breed I have feral Nubians on some land in Pecos County I inherited they do a good job of keeping the scrub down and I have never done anything to them other than not fence off the stock pond. Every year I shoot one or two for meat a quick 6.5mm to the boiler room and it’s cabrito for weeks. I would encourage anyone serious about having a on site meat source to look at Nubians or Boer goats.
