Abstract excerpt
BACKGROUND: Reproductive efficiency is an important component of profitability and sustainability in beef cattle production, particularly in tropical environments where animals are routinely exposed to environmental stressors. This study aimed to identify environmentally sensitive SNPs associated with sexual precocity traits in Nellore cattle and characterize candidate genes and biological pathways regulating...
