Description
Shan Gao and co-authors feed marigold lutein to laying hens and track where the pigment goes, in a research paper from 2026. Lutein colors egg yolks, but the best dose, build-up time, and wash-out after feeding stops were not well mapped. Liver and ovary responses also needed study.
Four hundred fifty hens got feed with no lutein or with set doses for twelve weeks. Laying output and standard egg traits did not change. Yolk color rose fast with dose, then fell sharply a few days after lutein stopped. High doses packed less efficiently per unit. Blood and hormone shifts linked liver and ovary action.
