Shell gland RNA-seq reveals key genes regulating eggshell quality and potential links between eggshell quality and hatchability across different laying stages [PDF]

Poultry Science
The quality of hatching eggs and their hatchability are key factors affecting the production efficiency of breeding flocks. The quality of hatching eggs is commonly graded directly based on the eggshell quality.
