Would it be any different? I mean, we breed as much food animals as we slaughter, the only difference is a time lag e.g. today's number of slaughtered chickens should match the the number of chickens bred in March; today's number of bred chickens will be a bit different than today's slaughtered chickens if farmers expect that in June people are going to eat more or less chicken due to Covid or something.
