“…Additionally, the ESS, EST, ESR, SUW, and ESMT of the DWL-White hens were significantly lower than those of the GF (p < 0.01), indicating that the mechanical properties of the GF eggshells were better than those of the DWL-White hens, consistent with Petersen and Tyler's [18] description that the ESS of GF was higher than that of laying hens. The correlation coefficient between the EST and ESS was 0.33-0.47 [15,16,42], and the correlation coefficient with the ESR was 051-0.74 [43]. Therefore, EST is an important factor that affects the ESS and ESR.…”

The decrease in eggshell quality seriously affects production efficiency. Guinea fowl (GF) eggs possess strong eggshells because of their unique crystal structure, and few systematic studies have compared laying hen and GF eggs. Sixty eggs were collected from both 40-week-old Dwarf Layer-White (DWL-White) laying hens and GF, and the eggshell quality, ultrastructure, bubble pores, and composition were measured. The results showed that the DWL-White eggs had a higher egg weight and a lower eggshell strength, strength per unit weight, thickness, and ratio than the GF eggs (p < 0.01). There were differences in the mammillary layer thickness ratio, the effective layer thickness ratio, the quantity of bubble pores (QBPs), the ratio of the sum of the area of bubble pores to the area of the eggshell in each image (ARBE), and the average area of bubble pores (AABPs) between the DWL-White and GF eggs (p < 0.01). The composition analysis demonstrated that there were differences in the organic matter, inorganic matter, calcium, and phosphorus between the DWL-White and GF eggs (p < 0.01). There were positive associations between the mammillary knob number in the image and the QBPs and ARBE and a negative correlation with the AABPs in the DWL-White eggs (p < 0.01). This study observed distinctions that offer new insights into enhancing eggshell quality.
