Ovalbumin gene polymorphism: Implications for hatchability and egg quality changes during storage in Japanese quail.

ABSTRACT: The aim of the study was to identify polymorphisms in the ovalbumin gene - SERPINB14 gene and evaluate their effect on hatchability traits and egg quality changes during storage in two strains of Japanese quails: meat-type (F33) and laying-type (S22). To individually determine hatchability traits for each female, eggs were collected and incubated. To determine egg quality traits, 10 eggs were collected from each female and stored for 14 weeks. Egg quality was analyzed 10 times during storage. All exons and the 3'UTR of the SERPINB14 gene were sequenced. A total of 17 SNPs were identified in both strains: 4 in exons, 5 in the 3'UTR, and 8 in intron regions. Association analysis showed significant effects of SNP14 and SNP16 on the percentage of late died embryos. Fresh egg weight in F33 fema
