Visualization of differentially expressed genes (DEG). (A) total number of DEG, including those up- and down-regulated in the piglets in the CP17 compared to the CP20 group. (B) Heatmap of normalized expression level of the 900 DEG for each sample, represented as z-scores. CP20 = pigs fed the regular diet containing 20% crude protein; CP17 = pigs fed a diet containing 17% crude protein. Dendrograms represent relationships between samples (columns) and genes (rows) based on complete linkage clustering.
