¹Body weight measured at d28

²Feed conversion ratio measured during the finisher period (d 24–28)

³Sum of acetate, butyrate, propionate, isobutyrate and isovalerate in the ceca, expressed on dry matter basis

⁴Standard error of the mean (n = 6). ^#In case of missingness, the adjusted SEM value (n = 5) is presented

⁵Estimated by one-way ANOVA. The significance threshold was P < 0.05. Values within column bearing different lowercase letters as superscripts differ significantly at P < 0.05 (Tukey's HSD test)
