“…Regarding eggshell quality, the ELL, ESL, ESA, and EW of the DWL-White hens were significantly higher than those of the GF (p < 0.01). The ELL, ESL, and ESA reflect the egg size, determined by the EW as a whole, and the egg weight of laying hens of the same breed is positively correlated with weight [40]. In this study, the EW of the DWL-White hens was higher than that of the GF, which may be attributed to the increase in the EW of the commercial laying hens represented by the DWL-White hens via systematic artificial selection [34,41].…”

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.

“…The variation in heritability may be attributed to the fact that the formation of translucent eggs is not complete within 120 h and storage conditions have a significant impact ( Fu, 2019 ). In addition, studies by Wang and Fu suggest that the heritability of translucent eggs falls within the range of 0.2 to 0.3, indicating a moderate level, with relatively poor genetic correlation with other phenotypes ( Wang, 2017 ; Fu, 2019 ; Qu, 2021 ; Liu et al, 2023b ). Regarding genetic studies, Wang identified four significant single nucleotide polymorphisms (SNPs) and 170 SNPs associated with translucent eggs, mainly located on chromosomes 2 and 19, corresponding to quantitative trait locus regions for eggshell color, body temperature, and abdominal fat rate ( Wang, 2017 ).…”

“…The egg production would have achieved at peak production depend on the feed, management, and economical value (Zarghi et al, 2023). Egg pro Age at first laying indicates that the duck is sexually mature, although ovulation may have occurred (Liu et al, 2023). Mass production as a very important variable is related to the selling price of duck eggs at the market level.…”

The purposed of this research was to identification effects in the different carotenoid on external and egg yolk quality of Alabio laying ducks (Anas plathyrhyncos borneo). To begin with, the carotenoid was identification using High Performance Liquid Chromatography (HPLC) for lutein content. Second, 200 day-old-Alabio laying ducks by age 4-5 months was used in this study. The basal diet was used in this study T0: basal diet, T1: basal diet + 10% lutein, T2: basal diet + 20% lutein, T3 basal diet + 30% lutein, T4 : basal diet + 40% lutein. A completely randomized design was adjusted with five treatments and six replications for each pen, consisting of ten Alabio laying ducks. A general linear model was used in this research to identification a significant effect. The results showed used different carotenoid give insignificant difference (p < 0.05) on the whole egg quality and yolk quality. In summary, even though present slightly different the carotenoid can be used as natural pigmentation on Alabio laying ducks.
