Note: The data were shown as means and standard error (SEM) (n = 6). The different lowercase letters in the same rows indicate significant difference (p < 0.05), while the same or without lowercase letters in the same rows indicate insignificant difference (p > 0.05). BW: Body weight; ADG: Average daily gain; ADFI: Average daily feed intake; FCR: Feed conversion rate; CON: basal diet group; ANT: supplement with 500 mg/kg oxytetracycline calcium; LAG: supplement with 150 mg/kg Astragalus polysaccharides and 75 mg/kg Glycyrrhiza polysaccharides; HAG: supplement with 300 mg/kg Astragalus polysaccharides and 150 mg/kg Glycyrrhiza polysaccharides.
