Data represent of three replicates (). Values in the same line with different letters are significantly different () based on Duncan’s test. The lack of superscript letter indicates no significant differences among treatments. Two-way ANOVA followed by Student-Newman-Keuls (SNK) multiple comparison test was conducted to investigate the interaction effects of sterol sources and levels. FBW = final body weight; WGR = weight gain rate; SGR = specific growth rate; FCR = feed conversion ratio.
