Fig. 3From: Heat stress affects fecal microbial and metabolic alterations of primiparous sows during late gestationEffects of late gestational HS on the relative abundance of fecal dominant bacterial genera (a) and OTUs (b) in primiparous sows (relative abundance > 1%). The significantly changed genera and OTUs were presented (P < 0.05). The values were presented as the medians, with six or five sows per group. Statistical differences between two groups at each day were calculated by the Mann-Whitney U test. HS = heat stress; TN = thermoneutralBack to article page
