a–e within the same row means that those with different superscripts are significantly different (p < 0.05). Values represent the mean of eight replicates. NSD: normal stocking density (10 birds/m 2), HSD: high stocking density (16 birds/m 2), Se: selenium, SeNP: selenium nanoparticles, MOS: mannan oligosaccharide, BW: body weight.
