Predictive Equations for Alfalfa Quality (PEAQ) Readings
Extension Dodge County and the Dodge County Forage Council are collecting biweekly PEAQ readings and scissor clip forage analysis starting in May and continuing as long as their alfalfa is standing.
Predictive Equations for Alfalfa Quality (PEAQ) is a method to measure standing alfalfa’s forage quality before it’s harvested. Agronomists at the University of Wisconsin – Madison developed this method to help predict alfalfa’s Relative Feed Value (RFV) at the time of cutting.
First-crop alfalfa can rapidly drop 3-5 points of RFV per day as plants mature. Alfalfa quality should be 150 RFV for milking dairy herds and 120-130 RFV for heifers, stocker cattle and lactating beef cattle.
