Abstract: The aim of this study was to design and apply the measuring acquisition system, or a device for determining the limit values of eggshell stress using the puncture method. This study focused on class "L" eggs produced on a laying hen farm in the vicinity of Čаčak and determined the external physical properties of egg quality: length, width, shape index and mass. In addition, the following eggshell properties were determined: mass, proportion, thickness, and puncture force. The average egg length was 58.05 mm, width 45.46 mm, and shape index 78.25%. The average egg mass was 65.89 g, and the eggshell ratio 12.76% (8.44 g). The average eggshell thickness was 0.48 mm with a 4.69% coefficient of variation. Results showed that the tested eggs had uniform stress, with an average value of the minimum shell puncture force 26.34 N, with a 0.95% coefficient of variation.
