Actual values for control birds were (average per bird per 7 d): feed consumption, 106.8 g; weight gain, 50.4 g; and F/G, 2.12 g/g
2 Significance of effect from ANOVA; Interaction effects between OA concentration and charcoal concentration were not significant (p > 0.05) for relative
weight gain and feed to gain ratio
a-c Means within each performance parameter grouping are significantly different (p < 0.05) according to the Student-Newman Kuel's test (20)
