Main effect of diet using one-Way ANOVA.
Pairwise comparisons between dietary treatments were performed using Dunnett's multiple comparison with formaldehyde designated as the control. Significance is denoted in bold with a P ≤ 0.05.
The negative control (NC) fed birds had 8 replicate pens (n = 8).
Experimental diet fed birds, Formalin (F), 0.25% Amasil NA (AML), 0.5% Amasil NA (AMH), and SILO Health 104L (SILO) had 10 replicate pens (n = 10).
