I agree with you my fellow Scotsman! We had rabbits and chicken growing up but I like milk too! You can pressure cook and can the meat which I have done this year and it is awesome. I actually had lamb chops for the first time in my life a couple of nights ago. It tasted like some of the best beef I have ever had. That appears to be an option too.
Didn’t think of canning meat. Hmm. I raised cows and they eat a lot of grass. You need some pretty good acreage to support that. Couldn’t keep them right next to the house to keep an eye on ‘em like you can chickens and rabbits. In the winter you’d have to have a lot of hay. I love beef, but I think that it would be too labor intensive. As for milk, that’s for calves and babies. LOL!
We have lots of feral pigs here abouts. I’ve killed six the last six months or so. They taste quite good.
We had sheep, as well. Had a heck of a time keeping the lambs out of the mouths of coyotes. Not a bad option, though. They need less land and can eat a larger variety of plants.
