SS = sodium selenite; SM = DL-selenomethionine; SY = selenium enriched yeast; NS = nano-selenium.

^a–c Values within the same column with different superscript letters differ (P < 0.05).

¹

Meat quality characteristics data are means of duplicated analysis of 24 samples per each treatment.

²

Measurements were performed at 24-h post mortem.

³

Inorganic source of selenium was sodium selenite vs. organic sources of selenium including SM and selenium enriched yeast.
