Description
A sow that returns to heat promptly after weaning keeps a pig farm efficient, and her gut fungi may have a say in the timing. The authors profile fecal fungi with metagenomics in 85 sows and compare those that return to estrus on schedule with those that do not. Twenty-two fungal species differ between the groups. On-time sows carry more of one yeast, Arxiozyma slooffiae, and less of two others.
The fungi do not act alone: the favored yeast tracks with Prevotella bacteria also enriched in on-time sows, and the pair are predicted to swap metabolites such as iron and thiamine. A panel of fungal markers separates the groups well, and adding bacterial markers sharpens it further. Links to hormones run through the data too, with the yeast tied to plant estrogens and steroid pathways. The authors present the gut mycobiome as an overlooked player in sow fertility.
