Total VFA: acetic + propionic + butyric + branched VFA + other VFA; Βranched VFA: isobutyric + isovaleric + isocaproic; Οther VFA: valeric + caproic + heptanoic.

Basal diets based on maize (M) or wheat (W). Data shown per CT represent treatment means from 15 broilers (e.g. 5 from treatment M0 + 5 from treatment M100 + 5 from treatment M150).

3

Phytogenic supplementation (0, 100 and 150 mg/kg diet). Data shown for PFA represent means from 10 replicate pens (e.g. 5 from treatment M0 + 5 from treatment W0).

4

Interaction means (treatments) for 5 battery cages per treatment.
