ABSTRACT
This experiment was designed to study the
effect of storage method (room temperature air tight box and refrigerator) and
duration of storage (7,14,21 and 28 day) on Bovan brown egg at different stages
of production (30,52 & 72 weeks) .The result of this study shows that
refrigerated eggs has better Haugh unit when compared with eggs stored at room
temperature and air tight box. The increase in time of storage regardless of
the temperature caused loss in the internal qualities of the eggs. The result
also show that age of the birds has influence in all the parameters evaluated
except shell thickness and yolk width.
