The aim of the study was to examine the influence of the rearing system and age on the phenotypic correlation of the physical
properties of the eggs of the Banat naked neck layers. In both examined systems (extensive and semi-intensive system) there
were 50 Banat naked neck layers each. The egg properties were examined at three evenly distributed time intervals (40, 45 and
50 weeks of age) in the period from May to July. In order to determine the external properties of egg quality, three basic measures
were observed: egg weight, egg length and egg width. Based on the measured length and width of the eggs, the egg shape index
was calculated, and subsequently the volume and surface area of the eggs were determined. For each examined factor, the
correlation between the mentioned characteristics was determined. The obtained results showed a significant effect of the
rearing system on all examined egg properties (Р < 0.05), while the influence of age as well as the interaction of the... two examined
factors had no significant effect. The highest correlation among all investigated factors was found between surface area and egg
volume.
