Penn State Particle Separator - Penn State Extension

If rations or forages are too fine, feeding a small amount of long hay or baleage can improve the average ration particle size. Farms feeding 5 or more pounds of long hay per cow daily would not likely have problems with overall particle size. Many farms, however, do not...
