^{a, b, c}

Means within a row with no common superscripts differ significantly (P < 0.05).

Data are the mean of eight replicates; CHO, cholesterol; MDA, malondialdehyde; SEM, standard error of mean; Ctrl, the birds fed the basal diet; Norm, the birds fed 0.3 mg/kg of Se provided by sodium selenite; SS, SEY, and SEIP, the birds fed 2 mg/kg of Se provided by sodium selenite, Se yeast, and Se-enriched insect protein powder, respectively.
