When I first got my show heifer I inquired with my feed dealer about beet pulp, he said "it has no nutritional value really, it is just to tighten the rib." What does "tighten the rib" mean? Do you feed it all the time, or just before shows? How much per day? I have a neighbor that has 2 silage bags of beet tailings, is that about the same? Right now she is getting sweet mix, oats, and a little bakers bran with show bloom. Along with free choice hay/alfalfa mix.
