Abstract

 

Data on egg weight (g), egg length (mm) and egg width (mm) were taken and recorded on three hundred eggs (300) selected at random before they were broken to obtain data on shell weight (g), shell thickness (mm), shell ratio (%), shape index (%), egg surface area (cm2), unit surface shell weight (cm2/mg), yolk weight (g), yolk diameter (mm), yolk height (mm), yolk index (%), yolk ratio (%), haugh unit (%), albumen weight (g) and albumen height (mm). A number of equations were developed to predict various egg traits like egg weight from egg length and width, shell weight from the values of egg length, width and weight, eggshell thickness from egg length, width and weight, Albumen height from egg weight, width and length, Height of egg albumen from egg weight, width and length and weight of egg yolk from egg weight and width.

 

Key words: Egg weight, egg length, egg width, predict.
