1 Data are means of 6 replicates of 2 samples each. SEM, standard error of mean. CON, the diet supplemented with 0 mg/kg selenium (Se) (basal diet); SS, the diet supplemented with 0.3 mg/kg Se from sodium selenite; SEY, the diet supplemented with 0.3 mg/kg Se from Se-enriched yeast; SEC, the diet supplemented with 0.3 mg/kg Se from Se-enriched Cardamine violifolia; SEC + SEY, the diet supplemented with 0.3 mg/kg Se from Se-enriched Cardamine violifolia and 0.3 mg/kg Se from Se-enriched yeast; HU, Haugh unit. 2 St means storage time. 3 D means diet and D × St means the interaction between diet and storage time.
