Field checks still matter
Before hay reaches a lab report, buyers can look for clean smell, reasonable color, good leaf retention, minimal weeds, limited dust, firm bales, and dry storage. Those checks help identify whether a lot is worth a closer look.
What a forage test can explain
Common lab terms include dry matter, crude protein, ADF, NDF, TDN, minerals, RFV, and RFQ. OSU Extension notes that NDF is tied to intake potential, ADF is tied to digestibility, and RFV/RFQ are comparison tools rather than ration formulas.
