Description
Xiaofan Yu, with ten colleagues, reports a 2026 study of gene activity behind eggshell formation in laying hens. Shell quality drives farm profits, and thin or cracked shells waste eggs and raise costs. The team tracked how mineral builds up across three stages, from before it starts to the fast growth phase.
Gene reads from the uterus, the organ where the shell forms, were grouped by stage and network pattern. Early on, a protein called ovalbumin ran high and may stop crystals from forming too soon. In the fast phase, shell matrix proteins plus calcium pumps and carriers worked together to hold calcium steady. Calcium in uterine fluid rose over time, then held flat through the fast phase. The gene map offers targets for breeding and feed plans.
