^a,b Means that do not share a common superscripted letter within a row for each parameter differ significantly from those of the basal diet (0.0%), as determined by the Dunnett test (p < 0.05). ¹ SEM = Standard error of means for diet effect. ² GA = gum Arabic response; L = linear response; Q = quadratic response.
