| Treatment | CON2) | ZB | SPL | SEM | p-value |
| Energy digestibility (%) | 79.55 | 78.45 | 84.54 | 1.766 | 0.640 |
Mean values represent 6 replicates per treatment; a chicken is the experimental unit.
CON, basal diet; ZB, 100 ppm of zinc bacitracin supplemented group; SPL, 250 ppm of sophorolipid supplemented group.
