Results are presented as mean, SEM, p value (n = 6). a,b In a row, means assigned different lowercase letters are significantly different (p < 0.05). Abbreviations: NC, control group; PC, antibiotic group; TB, tributyrin group; SEM, standard error of mean. BW, body weight; ADG, average daily gain; ADFI, average daily feed intake; FCR, feed conversion ratio.
