Data in the same column with different superscripts (A, B, and C based on two-way ANOVA) represent that the significant difference is discovered in the dietary protein level (P < 0.05), and those with different superscripts (X, Y, and Z based on two-way ANOVA) represent that the significant difference is discovered in the dietary lipid level (P < 0.05).
