Forage Testing Provided in Coordination With

Beer and Forage Center.png 
These analyses are for the testing of forage quality.

Approximately one-half gallon of sample (cored hay, chopped silage or haylage) is needed for analysis. Plastic bags with zipper closures work great for this use.
  • Hay — Obtain samples from approximately 10 bales. Best samples are obtained with the use of a forage sampling probe. Check with your local Extension office​ about the availability of these samples. For square bales, take one core from one end of each bale. For round bales, take a sample from each side of the bales. If grab samples are taken, be sure to obtain a representative sample.
  • Silage or Haylage — If haylage is in round bales, follow the same procedures as for round baled hay. If haylage or silage is chopped, then obtain two to three gallons of material from 10 to 15 places in the silo. Four upright silos, run unloader and collect on sample per minute for several minutes. In both situations, mix all of the collected material together, then fill sample bag with this mixture. Be sure to seal bag to ensure correct moisture determination.
