Effects of Age and Storage Duration on Relationships among Albumen Quality Traits and Egg Weight in Japanese Quails

Authors : Sedat Aktan

Abstract: A total of 154 Japanese quail eggs which were stored throughout 0, 1, 4 and 7 days at 18°C and 60% RH from 10, 15 and 20 weeks of age were used to investigate relationships among different measures of thick albumen quality and Egg Weight (EW). Eggs were weighed and broken onto a glass surface and Albumen Height (AH), albumen pH, logarithm of AH, Haugh Unit (HU) and Internal Quality Unit (IQU) were determined. It was also determined that the correlation coefficients and linear regressions among the examined measurements. Both the decreases in AH, log of AH, HU and IQU or the increase in pH denote any deterioration in thick albumen characteristics by the age of hen and/or the storage duration. The regression coefficient of the albumen pH on age of the quail hen was merely found to be insignificant and rest of the albumen quality parameters were negatively affected by the hen age increased with low R2 values. On the other hand, all of the regression coefficients of the albumen quality parameters on storage duration were found to be significant. While the albumen pH increased by increasing storage duration, rest of the other quality parameters were decreased by the prolonged storage. The R2 values for storage duration were found to be relatively higher and more respectable than for hen age. There is no significant and/or fixed association among the examined measurements. Thus, it is not possible to develop any generalized (i.e., valid in all cases) formula which assumed any fixed association such in HU or IQU. In conclusion, albumen quality variables must be used without any adjustment especially for the appropriate comparisons among diverse groups of eggs.
