Description
Older laying hens lay fewer eggs as liver and ovary function fade and hormone levels drop. Xu and co-authors feed 400 aged hens a plant compound, kaempferol, at four dose levels and track gut, liver, and ovary health along the gut-liver-ovary axis. They measure gut lining shape, barrier genes, blood fats, hormone levels, and egg output.
The mid-range dose of 150 milligrams per kilogram worked best: gut barriers strengthened, liver fat fell, egg-making genes and hormones rose, and egg output improved. The compound also boosted the ovary's defenses against damage. The authors name that dose as the sweet spot for aged flocks.
