^a–c Means with different superscripts differed at p < 0.05. Superscripts are only shown when main effect of treatment had a p < 0.05 (n = 13 pens/treatment). ¹ Produced by the catalytic oligomerization of food sugars into tailored glycans [3,4] (Midori USA, Inc., Cambridge, MA, USA, DSM Nutritional Products, Kaiseraugst, Switzerland).
