EFFECT OF POSITIONING AND DURATION OF STORAGE ON THE EGG QUALITY OF ISA BROWN CHICKENS

This study examined the effect of positioning and duration of storage on the egg quality of ISA Brown chickens. Eggs from ISA Brown layers were stored under controlled conditions and arranged in different storage positions for varying periods. The aim was to determine how storage orientation and length of storage influence both internal and external egg quality parameters. Key quality indicators such as egg weight, shell strength, albumen height, yolk index, and Haugh unit were evaluated at different storage intervals.

The results indicated that prolonged storage duration led to a gradual decline in egg quality, particularly affecting albumen thickness and yolk stability. Eggs stored for longer periods showed lower Haugh unit values and reduced internal quality compared to freshly stored eggs. Storage positioning also had noticeable effects, as certain orientations helped maintain better structural integrity and reduced quality deterioration over time.

The findings suggest that both storage duration and positioning play important roles in preserving egg quality after laying. Proper storage practices can therefore help maintain the nutritional and market value of eggs from ISA Brown chickens. It is recommended that eggs be stored for shorter periods and in appropriate positions to reduce quality loss and ensure better consumer acceptability.
