Abstract

Grazing preference of 8 tall fescues was evaluated by 1) clipping and weighing forage before and after grazing (CW), 2) a
selection ratio (SR), and 3) preference scores (PS). The coefficients of variation were 96, 52, and 20% for SR, CW, and PS
methods, respectively. The ranking of preference was similar for CW, SR, and PS methods. The PS method was done in 6% of the
time and with less error than CW and SR, used the entire row, and was nondestructive.
