Abstract: A total of 240 eggs from two commercial layer strains (ATAK and ATAK-S) at 30 and 40 weeks of ages were used to investigate relationships among measures of thick albumen quality and Egg Weight (EW). Eggs were weighed and broken onto non-reflective glass surface and Albumen Height (AH), Albumen Index (AI), Haugh Unit (HU) and Albumen Area (AA) were determined. The AA was calculated by digital image analysis. The correlation coefficients among AH, AA and EW and the linear regressions of EW on AH and AA were determined. Regression coefficients of the AH on the EW were insignificant and were ranged 0.02-0.059 mm g^-1 showing that the fixed regression of 0.05 mm AH per gram of egg implied by the HU is wrong. The R² values were ranged 0.4-4.5% and were fairly poor. The regression of the AA on the EW was significant but a bit higher than of the AH. The slope was always positive and was ranged 0.611-1.430 cm² of AA g^-1 of egg. The R² values were ranged 7.5-21.1%. The EW was insufficient to determine both of AH and AA with a well fitted model. The fixed HU regression of AH or AA on EW is not adequate for diverse strain and age groups of eggs. The AH or AA alone will give a measure that is at least more accurate. However, image analysis to calculate irregular AA will provide an opportunity to easier and time-independent evaluation.
