Preweaning heat stress alters liver transcriptome and DNA methylation in dairy calves
30 Jan 2025
Abstract excerpt
Prenatal hyperthermia has long-lasting effects on dairy calf metabolism, immunity, and productivity. Yet, the effects of postnatal heat stress on neonatal calves remain unclear. As such, this study aimed to investigate the impact of heat stress on the preweaning dairy calf liver gene expression and DNA methylation profiles. Holstein dairy calves were exposed to summer heat stress (daily average...
