Important features identified by partial least square discriminant analysis model based on amines metabolites in serum at day 28 of experimental period. Metabolites with a high VIP score are predictive for certain diet, e.g., alpha-aminobutyric acid is predictive for DWP and 1-methylhistidine for YMW. The color boxes on the right indicate the relative concentration of the corresponding metabolites in each group under study. CAS, casein; DWP, partially delactosed whey powder; SBM, soybean meal; SDPP, spray-dried plasma protein; WGM, wheat gluten meal; YMW, yellow mealworm; VIP, variable importance in the projection. Values are the mean of six replicates.
