Principal component analysis of liver lipidome. Scores plot with plotted 5% confidence interval (A) and associated loading plot (B) of principal component analysis (PCA) of the liver lipidome of the broilers. Broilers were fed diets with either 0 (HI-0), 2.5% (HI-2.5) or 5.0% (HI-5.0) Hermetia illucens (HI) larvae fat for 35 d. Data are principal components (PC 1 or PC 2) and their loadings calculated based on the relative abundances of the lipid species within their lipid classes, n = 12–14 broilers/group. Abbreviations: Cer, ceramide; DG, diglycerides; LPC, lysophosphatidylcholine; LPE, lysophosphatidylethanolamine; PC, phosphatidylcholine; PC O, PC-ether; PE, phosphatidylethanolamine; PE O, PE-ether; PG, phosphatidylglycerol; PI, phosphatidylinositol; TG, triglycerides
