Zn = zinc; Mn = manganese; Cu = copper; Fe = Iron; SEM = standard error of the mean.

ZMCGly = Zn, Mn, and Cu bis-glycinates.

ZMCAA = Zn, Mn, and Cu amino acid complexed minerals.

Low level = 20, 20, and 3.5 mg of Zn, Mn, and Cu, respectively.

High level = 40, 40, and 7 mg of Zn, Mn, and Cu, respectively.

A,B Within a column, values with different letters differ significantly from the source by Tukey's test (P < 0.05). a,b Within a column, values with different letters differ significantly from the level by Tukey's test (P < 0.05).
