From: Comparison of canine colostrum and milk using a multi-omics approach
Milk metabolome compared across two timepoints. LC-MS was used for untargeted metabolomics of canine colostrum (N = 24) and milk (N = 24) collected eight days apart. (a) A heatmap of metabolites separated by time of lactation, normalized to range from 0-100%. Red signifies upregulated metabolites and blue signifies downregulated metabolites. (b) Principal component analysis (PCA) of the overall metabolite profile, showing the first two components that explain 16% and 14% of the variability between samples, respectively. When coloring samples by timepoint, a clear separation is observed signifying different colostrum and milk metabolome profiles
