The data were written as the mean values ± standard deviation (SD).

The p values were calculated using Anova test (^*p < 0.05; ^**p < 0.01; ^***p < 0.001).

^a,b,cRepresent different superscripts differed significantly (p < 0.05).

The major categories were arranged in order of abundance at each dietary animal protein medium.

The numeric values represented the number of reads.
