AB  - 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.

AB  - In this paper the results of analysis of different source of variation that have influence on daily gains of simmental bulls in test are presented. The analyzed factors were year and month of calving, herd of origin and group in test. Year of calving was important source of variation for almost all daily gains while influence of month of calving as well as influence of group in test varying and depends on the nature of daily gains. Herd of origin was not significant source of variation for daily gains in test while was significant for ADG before test as well as for lifetime ADG.
AB  - U radu su prikazani rezultati analize različitih izvora vrijabilnosti koji svoj uticaj ostvaruju na prosečne dnevne priraste simentalskih bikova u performans testu. Ispitivani su uticaji godine i meseca teljenja, matične farme i grupe u testu. U zavisnosti od osobine, uticaj pojedinih faktora na varijabilnost prirasta je bio različit. Godina teljenja je bila važan izvor variranja za skoro sve analizirane priraste, dok je značajnost meseca teljenja, kao i grupe u testu varirala od prirasta do prirasta. Matična farma nije bila značajan izvor variranja za priraste u testu, ali je bila značajan za prirast pre testa i životni dnevni prirast.
