Need 50 lbs in 30 days. Hog will only eat 2-3/4 to 3lbs morning and 2-3/4 to 3lbs night. Whats out there that will do it ?

248 lbs with 270 lb target. 26 days to go. He does need a little more in the ham as well. Trying to figure out what will deliver ham muscle but keep the ADG under 1 lb a day. Is it possible?
