Abstract: The decline in the quality of eggshells can cause loss of economic benefits and food safety risks. The transport of inorganic calcium ions (Ca2+) in the uterus of laying hens involves different transmembrane pathways, ion homeostasis, and the expression of related transport genes and vectors, which is an important link in eggshell mineralization and regulation. This article reviews the effects of uterine Ca2+ transport pathway, Ca2+ transport on eggshell mineralization and eggshell quality, and the regulatory effect of nutritional factors on Ca2+ transport, aiming to provide reference for improving eggshell quality by regulating eggshell mineralization.

Key words: eggshell quality, eggshell mineralization, calcium ion transport, nutritional modulation, laying hen
