Genome-Wide DNA Methylation Differences between Bos indicus and Bos taurus

open access: yesAnimals, 2023
Disease risk is a persistent problem in domestic cattle farming, while economic traits are the main concern. This study aimed to reveal the epigenetic basis for differences between zebu (Bos indicus) and taurine cattle (Bos taurus) in disease, disease resistance, and economic traits, and provide a theoretical basis for the genetic improvement of ...
