SEM, standard error of the mean; FBR, fermented biogas residue; ADG, average daily gain; ADFI, average daily feed intake.

¹⁾Data are the means of 4 replicates of 8 pigs per pen.

²⁾FBR5, the diet contained 5% FBR; FBR10, the diet contained 10% FBR; FBR15, the diet contained 15% FBR.

^a–cMeans in the same row with different superscripts differ (p<0.05).
