Small superscript letter are different (P < 0.05).

¹Values means n = 8 for productive performance.

²NC = negative control, no antibiotics; PC = positive control, antibiotics included; OA1 = NC plus organic acid 1; OA2 = NC plus organic acid 2; OA1 + OA2 = NC plus organic acid 1 and organic acid 2.

³Pooled SEM; n = 8/treatment.
