I know I go through more than I should, but I'm trying to change that. I've got goats & zebu that get into the feed periodically if I'm not paying attention & leave the gate open.
I've also cut down on how much they are given on a daily basis, making sure they eat what they are given & not leaving it overnight...and closing the gate! On my days off I am also letting them free range all day, so that's helping some. I hope to be down to at least 50 lbs or less during the winter, less in the spring.
