My point is, five different people using five different types of feed is not helpful advice. Everyone swears by their personal favorite. A search for "show cattle feed" will give you the same five choices. Universities spend thousands of our tax dollars to figure out what works best. Feeding a show heifer is no different than feeding a replacement heifer. Show cattle need the same protein, fat, vitamins, etc. that commercial/seedstock cattle do. Learning what each component of a feed mixture does, will help to determine what your cattle are lacking. There is no magic ingredient in feed. A smart person would compare the nutritional analysis on all the feeds, and find out that they are all very similar. A little research will give you the information to design your own mix, that will be 1/2 the price, and work as well or better than the commercial mixes.
