a, b Interaction means within the same column differ significantly (P ≤ 0.05).
1
No: no OABF addition; Yes: addition of 1 g OABF/kg diet.
2
No: no avilamycin addition; Yes: addition of 2.5 mg of avilamycin/kg diet.
3
Interaction means from 8 replicate pens per treatment. Treatments include: control – no additions (CON), 1 g OABF/kg diet (OA), avilamycin 2.5 mg active components/kg diet (AV) and combination of OA + AV (OAAV).
4
Pooled standard error of means.
