Abstract
Haugh unit which introduced by Raymond haugh in 1937 is the most scale used to measure the egg quality by equation ( HU= 100*Log (h+7.57)-(1.7 * W 0.37 ) .The aim of this research is to find the prediction equation of the Haugh unit depending on egg weight and albumen height, where we calculate 1503101 value of Haugh unit using microsoft Excel spreadsheet functions and data of egg weight ranged from 40 to 65 gm by increment (0.01) gm , and albumen height from 4 to 10 mm by increment (0.01)mm . The results indicates that there was a significant positive correlation between haugh unit and albumen height (0.969) and negative correlation between haugh unit and egg weight (-0.215), and the ANOVA table show high significant effect of regression model (P ≤ 0.0001) with coefficient of determination R2 (0.985) which indicate that the prediction equation (HU = 58.235-0.334 W+6.256 A) can predict haugh unit with high accuracy.
