well, I've never made tallow (beef fat) because we don't raise cows (yet) and I don't know of a local source that does things to my liking. I really am a very picky person :)

I've only rendered lard from our own pasture raised pigs. We feed them organic grains, garden vegetables and all kinds of good stuff. We don't have pigs right now, not sure if my husband want' to do it this year or not.
