Diet composition of steers grazing adjacent monocultures of tall fescue and alfalfa using different combinations of n-alkanes (ALK) and long chain fatty alcohols (LCOH) as markers. Angular transformed standard error of the mean = 3.3. ^{†}Nontransformed percentage units. ^{‡}Four ALK plus three LCOH (ALK: C_{27}, C_{29}, C_{31}, and C_{33} and LCOH: C_{26}, C_{28}, and C_{30}), two ALK plus three LCOH (ALK: C_{29} and C_{31} and LCOH: C_{26}, C_{28}, and C_{30}), four ALK (C_{27}, C_{29}, C_{31}, and C_{33}), and two ALK (C_{29} and C_{31}). Within forage type, means followed by the same letter are not different at *P* < 0.05.
