Fig. 2From: Alfalfa-containing diets alter luminal microbiota structure and short chain fatty acid sensing in the caecal mucosa of pigsCaecal microbiota composition of pigs fed diets with 0% (CAE0) or 15% (CAE15) level of alfalfa meal (n = 4). Principal component analysis evaluated the overall structural changes of the gut microbiota between the CAE0 and CAE15 group (a).
