Abstract

Respiration is a fundamental physiological phenomenon of egg and egg gas exchange is realized through the shell. This study aims to reveal the relationship between egg respiration intensity and eggshell surface ultra structure. In this study $O_2$ flux via eggshell surface was selected as a symbol of egg respiration intensity and it was determined real-time dynamically based on Non-invasive Micro-test Technique (NMT). Images of eggshell ultra structure were acquired through High Magnification scanning electron microscopy. After processing the images, the distribution of stomata and roughness of eggshell surface was observed. Studies show that eggshell surface ultra structure morphology affect egg gas exchange, rougher surface and denser stomata promoted egg gas exchange. The greater the $O_2$ flow is, the rougher the surface and the larger hole density. The linear relationship between respiration and eggshell thickness, egg weight was not significant.

Keywords:
