In their current implementation, yeah, they’re pretty bad. There is a need for something like it, though. A sow will absolutely lay down on her piglets and suffocate them.
> A sow will absolutely lay down on her piglets and suffocate them. This makes me really curious because that behavior seems very maladaptive for a species. That leads me to wonder if something else, ie. the environment or domestication, is leading to this behavior rather than pigs being really, really prone to wiping out their own species. Does anyone know why they do this in a farm environment?
They reproduce very quickly - evolution is a numbers game, and yield isn’t part of the equation.
