Speaking of butchering.
In the topic of handling livestock >>35328 slaughtering also task we should think about. How to do it and if we can do it. Slaughtering a pig alone is a very hard and dangerous thing to do. Especially a grown fattened one, they are strong with lotsa weight. And then the processing of the carcass also a work intensive task. So both needs helping hands maids.
So picking out animals to keep as a foodsource has it's caveats. Knowing our limits help.
Probably goats are also a tricky species to slaughter, but still would pick them for the diary products.
Or maybe sheep. They give wool which can be used more flexibly for creating clothing than leather/skin/fur of a goat. I heard their milk in itself is too fatty to drink, but it can be turned into other products.

Btw first picrel is a breed of sheep called cikta originating from Germany, but today it can only be found here at us, and only a couple of herds, since it was replaced by breeds (like merino) which produce more meat and wool.
