I’ve had beef cows for about 3 years. I’ve never raised a freezer beef but had a couple people asking me about selling them one. I need a little direction. Typically one of my steers weighs 400 pounds at 6 months. I really don’t have a pasture I could wean the calf and keep him on grass. I’ve got a pen I can put him it’s about 40 foot by 40 foot. If I put him there at 6 or 7 months how much feed would he need daily? And how long until he gets to about 600 pounds?
