Figure 1.

Hierarchical clustering analysis based on the differences in protein profile from day of hatch chick intestinal samples treated with either saline control (S), Citrobacter freundii (C), Citrobacter spp. (C2), or lactic acid bacteria (L) into the amnion as pioneer colonizers. Each sample is a composite of 3 chick intestines and 3 bioreplicates for each treatment. Tree connections show the distance from each sample; the shorter distance or closer the 2 samples are together, the more similar their profiles.
