Comparative evaluation of egg quality characteristics of three commercial layer strains in Chattogram, Bangladesh

Abstract

The study was undertaken to assess the comparative egg quality
parameters of three different commercial layer strains (Hisex brown,
Hisex white & ISA brown) such as Farm1(F1, Hisex brown), Farm2 (F2,
Hisex white), and Farm 3(F3, ISA brown), located in the different areas
of Chattogram, Bangladesh. Layer farms were selected randomly
depending on the number of criteria from the same locality during the
month of January to March 2024. A total of 300 egg samples were
collected randomly from 3 different commercial layer strains during the
study period to assess the egg quality traits or parameters. Farms or strains
were regarded as treatment; each treatment replicated ten times and ten
eggs per replicate. All the birds were reared in battery cages fed with
ready-made feeds under standard management and housing condition.
Data revealed that the egg quality parameters such as egg weight, shell
weight, shell percentage, albumen weight, albumen weight percentage
and yolk weight percentage) were significantly (P<0.05; P<0.01)
influenced by treatment except for yolk weight. The Haugh Unit (H.U)
score and albumen index were significantly (P<0.05; P<0.01) influenced
by treatment without showing any differences in shape index and yolk
index. Only albumen height differed significantly except for other
parameters (e.g egg width, egg length, albumen length, yolk height and
yolk length), were measured in this study. It is clear from the result that
the significantly highest egg weight, shell weight, albumen weight, yolk
weight percentage, albumen height (6.05 mm), albumen index, and H.U
score were found in the F3 compared to other farms (F2 and F1) in this
study. So it can be inferred that, ISA brown (F3) egg quality appears to be
comparatively better than that of other strains, as most of the egg quality
characters go in favour of this strain (F3) on the basis of the quality
evaluation measured in this study under commercial farming condition.
