when my kids first started showing pigs we had several that were not going to make weight. we fed them ice cream for several weeks talk about gain. pure fat. they would stand and lick the pans clean. after they started to gain we weaned them off the ice cream and upped the exercise, ended up with light weight champ and three class winners. now we use paylean and ADM fast fat. not together the fast fat works for structural problems. also using a product called in motion, has a glit that was real bad in front loosened up and almost normal.
