¹Data are expressed as means (n = 10). The main effects (the stocking density and concentration of supplemental dl-methionine) were analyzed by two-way ANOVA and Duncan’s multiple range test was used to compare the treatment means. Means in the same row without a common letter differ significantly (P < 0.05).
