Fig. 1. Concentrations of crude protein (CP) Fractions A, B, and C in limpograss herbage CP for canopies grazed at different heights and sampled in layers (U = upper, L = lower). Fractions include soluble (A), potentially degradable (B), and undegradable (C). The effect of canopy height on Fraction A was linear (P = 0.034) and quadratic (P = 0.023); the effect on Fraction B was quadratic (P = 0.023); and the effect on Fraction C was linear (P = 0.011).
