Abstract
The effects of egg size and egg shape type on external egg characteristics were studied. A 3x3 factorial experiment was conducted using a completely randomized design (CRD). The first factor was egg size, including size 1, size 2, and size 3. The second factor was egg shape type, consisting of pointed eggs, standard-shaped eggs, and round eggs. Data collected includes egg weight, egg index, eggshell color, and egg surface area. Statistical analysis was conducted using generalized linear models (GLM) and correlation coefficients. The study found that the egg size factor significantly influenced egg weight, egg length, egg width, and surface area. The egg shape factor significantly affected egg length, egg width, egg index, and yolk color, as measured by a colorimeter. The interaction between egg size and egg shape significantly influenced egg length and egg index. Correlation analysis showed that egg weight was positively correlated with egg size, egg length, egg width, and surface area, but not with the egg index. Egg shape was correlated with egg length, egg width, egg index, eggshell color, and yolk color, which in turn were correlated with values measured by the colorimeter. In summary, both egg size and egg shape influence certain external characteristics of eggs. The findings of this study may be useful in the design of breeding programs.
