Met = methionine; SAA = sulfur amino acid; BW = body weight; ADG = average daily gain; ADFI = average daily feed intake; F:G ratio = feed-to-gain ratio.

^{a, b, c} Within a row, means sharing different superscript letters differ significantly (P < 0.05).

¹BD, a corn-soybean basal diet with Met:SAA ratio at 0.51; L-MR, a plasma powder diet with a low Met:SAA ratio at 0.41; H-MR, a fishmeal diet with a high Met:SAA ratio at 0.61.
