Research on Microstructure and Component of Anas crecca crecca Egg Shell

[Objective]The aim was to analyze the reasons resulting in the brittleness of Anascrecca crecca.[Method]The structure of the eggshell crushed in hatching process was scanned and its basic elements were analyzed by using electron microscope and energy disperse spectroscopy.[Result]The basic structures of Anas crecca eggs were the same;however,there was great possibility that one of the main reasons affecting hatchability was the cracks in the outside surface of egg shell.[Conclusion]This study would provide a theoretical basis for the research on artificial incubation and the egg structure of Anas crecca.
