Cover Story: This study aimed to identify genomic regions linked to female fertility and characterize associated genes and pathways in Retinta beef cattle. Reproductive efficiency limits productivity, especially in local breeds under extensive systems, where low heritability and strong environmental effects hamper classical genetic selection focused on phenotypic controls. We applied a weighted single-step GWAS integrating pedigree, reproductive records of 44,000 cows, and genomic data of 1030 genotyped animals (65K). Notably, multiple regions associated with fertility were identified, including genes involved in ovarian function, cell cycle regulation, and hormonal signaling. These findings offer practical genomic tools to improve selection accuracy, accelerate genetic progress, and enhance sustainability of the Retinta breed. View this paper
