Eggshell quality was studied in two groups of Shaver hens (300 hens per group) 30 weeks of age. All hens received a basic diet of the same composition with pulverized limestone as a source of calcium. The experimental group received 2 g of granular limestone (particle size 1.1-1.4 mm) per hen per day during one week, adding on the concentrate in the afternoon. Significantly lower deformation (19 m), higher breaking force (4,1 kg) and shell thickness (39, 3 x 0.01 mm) were registered for eggs of experimental group of hens than for eggs of control group (24 m; 3.3 kg 36.5 x 0.01 mm, respectively). The results obtained in our investigation showed possibilities of eggshell strength improvement using 2 g of larger particle size of limestone as additional source of calcium.
Kokoši nosilje, uzrasta 30 nedelja su tokom sedam dana ogleda, pored kompletne smeše za ishranu, dobijale dodatno 2 g krupno mlevenog mermera, po nosilji na dan, posipanjem po hrani u toku popodnevnog perioda. Ovaj postupak je pokazao statistički značajan uticaj na poboljšanje čvrstoće ljuske. Dodatnom ishranom sa 2 g mermera po nosilji na dan ostvarena je statistički značajno manja vrednost deformacije ljuske uz istovremeno statistički značajno veće vrednosti sile loma i debljine ljuske u odnosu na kontrolnu grupu nosilja, koje nisu dobijale dodatne količine mermera.
