WebJul 19, 2024 · The top left panel shows RFV and RFQ values for legume hay are typically similar. As a report reviewer, I often do see alfalfa hay samples where RFV is equal to RFQ. In fact, approximately half of the legume samples displayed on Figure 1 have a difference in RFV and RFQ of plus or minus 10 or less. Grass Hay RFV and RFQ WebDec 22, 2024 · Perhaps most importantly, it’s critical to understand how, and within what situation, the data becomes meaningful. So, this time, let’s discuss relative feed value, or RFV. Relative feed value is used for forages, and in particular, for alfalfa forages, including dry hay and haylages of predominantly alfalfa composition. WebDec 21, 2024 · Then we combined those values to give an overall estimate of forage quality that we called RFV, which stands for relative feed value. RFV did a fair job of estimating digestibility of legume hay, but its major flaw is assuming all fiber has the same digestibility. quote of the dayssg
