    I don’t know anymore, sorry. It was some years ago in a study made by some German or Swiss scientists that was locked behind a paywall.
    I’ll have a look at the sci-hub and drop the link if I’ll ever find it!

    It was a very in-depth study also included mountainous regions where agriculture is not possible, the cows eat that grass and the waste of vegetables like husks and stems and stuff like that.
