| Bird eggs should have high internal and external quality to maintain the economic life of the product and hence recognizing and understanding the factors affecting egg quality have great importance. In this experiment, 18 healthy eggs were selected and then exposed to a 1.5 Tesla magnetic field. After this stage, 6 samples of them were immersed in sunflower oil and stored for two days. In the next step, length and width, failure force, thickness and weight of eggshell were measured. Then, the amount of shell density, volume spherical coefficient, and egg shape index were obtained using the desired formulas. Due to the effect of the calculated parameters on the failure force of eggshells, and in order to remove this effect, the calculated failure force was divided on the calculated parameter. The results of experiment showed that the highest ratio of failure force of eggshell on the parameters was related to the samples placed in the magnetic field and no immersed with sunflower oil. As in all cases was significantly different from control samples. The lowest amount was also attributed to control samples. In general, it was concluded that the presence of samples in the magnetic field increases the shell's resistance to failure, but samples that are immersed in sunflower oil had a lower failure force than those which are not immersed in sunflower oil. Finally, it can be concluded that with the presence of eggs in a high-power magnetic field, we can see an increase in the resistance force to the shell failure. | ||
