Most grain elevators and other feed dealers will mix and grind a ration to whatever formula you specify . . . and will either sell you the makings or process ingredients you furnish (for example, grain you've grown yourself or purchased from a farmer).
Protein formulation guide: Draw a rectangle on a sheet of paper and write in the center the percentage of protein desired for the ration. In the upper left-hand corner, jot the word "grain" and the assumed value of 10. Enter the word "supplement" in the lower left-hand corner, with the average figure for these ingredients. Then subtract diagonally — always taking the smaller number from the larger — and note the answers on the right. The figure in the lower right-hand corner is the amount of supplement, in pounds, you'll need to combine with the quantity of grain (also in pounds) shown directly above.
