not all that much as I've been trying to encourage him to eat hay instead - the pack recommends 80g a day for growing rabbits - i have been giving him something closer to 50g but he was underweight when I got him and he has so much growing to do that i'm worried about underfeeding him. He was on a different rabbit food from the breeder and fine on that, but i can't get it in my area so i gradually changed him on to this one (over 2 week period) and he's not really been happy on it. Quite a few normal poos, but there are a few runny ones there each day as well. I'm not feeding any veg as even tiny pieces of carrot seem to make him worse....
