In order to determine the characteristic structure of consumer eggs of light
line hybrids Isa Brown, and the correlation links between the eggs mass and the
examined characteristics, the research was conducted on the eggs taken from the
private farm “Poljoprom” in Vojkovici, Bosnia and Herzegovina. The eggs were
taken from three periods of production cycle, 20’n,28th and 48th week of age of
laying hens. In these periods, using random sample method, the appropriate
number of eggs was taken for a detailed examination, analysis and statistical
processing of eggs structure characteristics. During the production cycle the hens
were raised in modern facilities and adequate technology was used for each
particular aspect of production with all technological phases automatically
regulated.
Along with the age of laying hens, the absolute value of the eggs structure
(the mass of the shell and the membrane, egg whites and egg yolks) are usually
statistically increased at the level of P < 0.01, except at the mass of the shell of
laying hens in 48th week of age, where the significance was absent. The largest
relative share of shell (I4.4I%) was in fulI production, 28th week of age (WA28),
and the smallest (11.80%) in the middle of the production (WA48). Between
WA20 and WA28, the differences in relative part of the shell were not
statistically confirmed, while other differences were statistically significant at the
level of P < 0.01. The largest share of egg whites in the mass of the egg was in
WA4B (62.56%), and the lowest in WA28 (60.89%). The largest share of egg
yolk (26.80%) was at the peak of production (WA48), and the smallest (22.50%)
at the beginning of the production (WA20). All differences in terms of the share
of egg yolks and egg whites were statistically confirmed.
