Each value represents the mean ± SD of six replicates. Values with no superscript letter or the same superscript letter are not significantly different (P > 0.05); those with different superscript letters are significantly different (P < 0.05). NC: negative control; PC: positive control; BER: berberine-treated; LMY: lincomycin-treated; ADG: average daily gain; ADFI: average daily feed intake; FCR: feed conversion ratio.
