A new publication is available to help you understand the difference between relative feed value (RFV) and relative forage quality (RFQ) — two indexes used to assess forage quality. The more widely used RFV index assesses quality, compares forage varieties and prices forages. The newer RFQ index takes into account the differences in digestibility of the forage’s fiber fraction and can be used to more accurately predict animal needs and performance.
The three-page publication is available at the South Dakota State University dairy science Web site.
