The Impact of Different Plumage Color Selected Quail Lines on Egg Quality and Eggshell Properties

This study aimed to explore how different genotypes influence eggshell traits, egg quality, ultrastructure and nutritional value in egg quails during the egg production phase. Two breeder lines selected for six generations, brown quail and white quail, were subject to analysis, with 90 eggs examined for each genotype. At 42 days of age, 180 eggs were used, 90 from each strain for egg quality, eggshell characteristics and shell microstructure. The results indicated that the breed strain had a significant effect on various parameters, including egg weight, length, width, shape index, albumen height, weight and percentage, yolk height, diameter, index, weight and percentage, yolk-albumen ratio, shell weight and shell percentage. In particular, the white strain eggshell had different ultrastructure flaws than the brown strain. These included late fusion, poor confluence and different striations. Additionally, the egg quail showed a high content of polyunsaturated fatty acids. Different genotypes influence eggshell traits, egg quality and ultrastructure. Understanding these genetic variances can lead to improvements in egg production systems' overall performance and egg quality.
