This equation can be used as a tool for producers and feed processors to assess the economic impact of particle size reduction. For example, projected feed/ gain for 700 micron feed would be 3.36 based on the equation. If the particle size was increased to 1,100 microns, the projected feed efficiency would be 3.52 or an increase of about 5 percent.
