Websor, 1.29 in the RFV calculation was chosen so that the RFVof full bloom alfalfa has a value of 100. Example: Alfalfa hay or haylage with 32% ADF and 40% NDF (Plug in values for ADF and NDF on a dry matter basis) DDM = 88.9 - (0.779 x 32) = 63.97 DMI = 120 / 40 = 3 RFV = (63.97 x 3) / 1.29 = 149 WebThe biggest advantage of the dye system, says Henningfeld, is the lower cost and simplicity. While RFID tags alone cost about 69 cents each, $10 worth of dye will cover nearly 200 bales.

If a full bloom alfalfa hay contains about 41 percent NDF and 53 percent ADF, the calculated RFV is 100. The RFV is useful in the market for comparing hays. For example, Hay A and B have RFV values of 110 and 90, respectively. probiotics lower creatinine
