Particle Size (Chop Length) Testing

WHY, WHEN, WHAT, WHO AND PRINTABLE HELPS

Why evaluate Particle Size?

  • Correct chop length minimizes air (oxygen) in the pile or bunker
  • Correct chop length is important for fiber in the ration
  • Recommended corn Theoretical Length of Chop (TLC) is 1/2"  to 3/4". Grass and alfalfa TLC is 3/8" to 1/2" 

When should Particle Size be evaluated? 

  • Before harvest, set up a station at weigh scale or safe area
  • During harvest, once per hour, sample chopped silage before it is piled/stored
  • Run the Dry Matter Test and Kernel Processing Score Test at the same time for efficiency and maximum valuable data

What equipment is needed?

Who can run the test?

  • Anyone who can keep samples organized and do simple math on a calculator
  • Recruit and train two to three people to make sure tests are run over entire harvest
