Abstract:
A study was conducted with the objectives to determine the quality characteristics of egg of
three commercial strains under different storage conditions. For this purpose, a total of 270 eggs
of 3 different types of layer strain named Shuvra (S) or BLRI Layer-1, ISA brown (IB) and Bob
white (BW) were collected from 3 small-scale commercial poultry farms at the age of 55 weeks.
The eggs were stored for 0, 3 and 7 days at room temperature (20-25
0
C) during the month of
October. The egg weight, shell weight, shell thickness, egg width and egg length were studied as
external egg quality and the albumen height, albumen width, yolk weight, yolk height were
studied as internal egg quality. The study revealed that eggs of Shuvra had higher egg yolk and
shell weight (P<0.01) than other eggs while the albumen height was found almost similar in all
the hens eggs (P>0.05). The albumen height (P<0.05) and length (P<0.01) were also found
higher in Shuvra eggs compared to other eggs at all storage periods. The yolk and shell quality
of Shuvra eggs were also found better than all other eggs in different storage periods (P<0.01).
It was also observed that the major egg quality traits like albumin height, length, Haugh unit and
yolk quality were significantly P<0.001) affected with increasing storage length. The results of
the present study suggested that Shuvra egg deserve the better quality for the preference of both
the traders and consumers.
