Dietary L‐Tyrosine Sustains Egg Production and Quality by Modulating Promoter CpG Methylation, Gene Expression, and Hormone Profiles in Reproductive Signalling Pathways of Aged Laying Hens

open access: yesJournal of Animal Physiology and Animal Nutrition, Volume 110, Issue 5, Page 685-698, September 2026.
ABSTRACT Managing prolactin (PRL)‐mediated reproductive suppression is critical for maintaining egg production in commercial laying hens. L‐tyrosine (TYR), a precursor of dopamine (DA), may counteract age‐related reproductive decline by suppressing PRL, thereby sustaining productivity and egg quality in late‐phase laying hens.
