摘　　要：本文主要阐述了鸡蛋的形成、蛋壳及其内部质量的测定方法,蛋壳质量可通过蛋壳比重、蛋壳颜色、蛋壳强度、蛋壳变形(破坏性或非破坏性)、蛋壳重量、蛋壳厚度和蛋壳结构来衡量。鸡蛋的内部质量以蛋黄颜色、卵黄膜完整性和蛋白质量来衡量。蛋壳及其内部质量受蛋鸡品种、年龄、营养(如钙、磷、维生素、非淀粉多糖、酶、饲料污染)、应激、疾病、环境和饲养管理等因素的影响。因此,充分了解影响蛋壳及其内部质量的因素对后续提高鸡蛋品质至关重要。In this paper,the formation of eggs,the determination of eggshell and its internal quality are reviewed.The quality of eggshell can be measured by specific gravity,color,strength,deformation(destructive or non-destructive),weight,proportion,thickness and structure.The internal quality of eggs is measured by the color of yolk,the integrity of yolk membrane and the quality of protein.Egg shell and its internal quality may be affected by factors such as breed,age,nutrition(such as calcium,phosphorus,vitamins,non-starch polysaccharide,enzyme,feed pollution),stress,disease,environment and feeding management.Therefore,a full understanding of the factors affecting the quality of eggshell and its internal quality is essential for the subsequent improvement of egg quality.
