[Objective] The study aimed to know about the physical characteristic of Gushi Goose egg and provide the reference for selecting the hatching egg of Gushi Goose.[Method] Fifty-six hatching eggs of Gushi Goose were selected to determine their egg weight,egg specific density,part proportion of egg components,shell thickness,albumen height,yolk Roche color and count the Haugh unit and the rate of blood and meat-spot.[Result]The average egg weight of Gushi Goose egg was 159.1g with greater variation.The egg specific density was 1.119,being at a high level.The egg shape index was 1.49,being at ideal level.The shell thickness was 0.514 mm and Haugh unit was 107.77.Proportion of albumen,yolk and shell were 49.56%,38.12% and 12.32%,resp.The rate of blood and meat-spot of eggs was 3.57%,being at lower level.Egg yolk Roche color was 4.52,being canary and needing to be improved by feeds.[Conclusion] Gushi Goose egg had greater specific density,moderate shell thickness and good shell quality,but its yolk color was lighter.It was suggested that the complete formula feed with corn as main shoule be used to feed the laying goose so as to increase the feed conversion rate and improve the yolk color.
