relative forage quality

Relative forage quality (RFQ) is similar to relative feed value (RFV) in that it is an estimate of overall quality of a forage, but it differs in the way it is calculated. RFQ takes total digestible nutrients (TDN) into account rather than digestible dry matter calculated from acid detergent fiber (ADF) values. This TDN, combined with dry matter intake, is derived from in vitro estimates of digestible fiber. The RFQ value is considered an improved method over RFV and is rapidly becoming the new ‘standard’ in forage quality testing.
