The aim of this research was to examine the influence of the year (production
cycle) and laying age on the quality of eggs for consumption. Examination of
certain properties of egg and shell quality was carried out over a period of
three years continuously and in four evenly spaced time intervals (24, 35,
46, and 57 weeks of age). Determining the external quality of eggs included
determining the weight and shape index. Examination of the internal quality
of eggs included the determination of albumen height and Haugh units. At the
same time, the quality of the eggshell involved the determination of the
following properties: (weight, thickness, deformation, breaking force, and
color of the shell). The obtained results showed that during three
production cycles, the genetic progress of this hybrid was confirmed, which
is primarily reflected in a statistically significantly higher (p<0.05)
value of egg weight, egg white height, and Haugh's units in the third year
compared to the first year examinations. Also, under the influence of this
factor, statistically significantly higher values of weight and shell
thickness and a darker shell color were determined in the third compared to
the first year of research. No statistically significant differences were
found for other examined parameters under the influence of this factor. In
the presence of statistically significant influence (p<0.05), various laying
ages were systematically examined for internal and external egg quality
attributes alongside shell quality properties, excluding shell deformation.
Egg weight increased significantly with increasing laying age, while shape
index values, contrary to egg weight, decreased. The parameters of internal
egg quality were worse with increasing laying age. Regarding the shell
quality properties, it was found that the shell weight and thickness,
similar to the egg weight, increased with the age of the layers, while the
breaking force was found to be the lowest in the oldest layers. The
interaction of both tested factors did not cause a statistically significant
effect on tested egg quality traits.
