I am trying to be pro-active here. I have a heifer that needs some expansion to her rib, a bigger bellied look. There are a lot of posts on here about how to get fill in a heifer at a show, but what I would like to know is what in a feed program is crucial to developing a heifer with that "barrel bellied look". Do you want more fiber, energy or protein. I am feeding a ration similar to that of kent show grower with free choice grass hay.
