Title: Effects of Pore Number and Eggshell Thickness on Muscovy Egg to Hatching
Abstract:We separatly measurate eggshell pore number and eggshell thickness of muscovy duck′s hatching eggs in this experiment,the first candling normal eggs,the first and third candling addled eggs,the pipped...We separatly measurate eggshell pore number and eggshell thickness of muscovy duck′s hatching eggs in this experiment,the first candling normal eggs,the first and third candling addled eggs,the pipped eggs and the normal hatching eggs at the same time.The result indicates that the average pore number of the first,third candling addled eggs and the pipped eggs are all significantly less than that of normal eggs.But the thickness of the third candling addled eggs′ and the pipped eggs′ are significantly more than that of normal eggs′.We observe the eggshell of the normal eggs,the pipped eggs and the normal hatching eggs with scanning electron microscope.The result shows that the structure of eggshell is the similar to the other poultry egg.And the thickness of pipped eggs(0.395~0.401mm)is significantly more than that of the normal hatching eggs(0.363mm).Read More
