NC, negative control; OA, organic acid: fumaric; EO, essential oil: thymol.

Inclusion levels: microencapsulated fumaric acid: 1.5 g/kg; microencapsulated thymol: 3 g/kg; non-microencapsulated fumaric acid: 0.9 g/kg; non-microencapsulated thymol: 0.6 g/kg.

Different letters indicate significant difference between the seven dietary treatments at p ≤ 0.05.

Data are presented as mean (n = 10 replicates/group for all evaluated parameters).
