Mn-MHAC = manganese methionine hydroxy analog chelated; BW = body weight; ADG = average daily gain; ADFI = average daily feed intake; F:G = feed-to-gain ratio.

^{a, b, c} Values in the same row with different superscript are significantly different (P < 0.05) by one-way ANOVA.

¹Data are means of 6 replicates of 12 broilers per dietary treatment.
