In Utero Heat Stress Programs Reduced Performance and Health in Calves
Heat stress during late gestation adversely impacts the developing calf. Calves that experience heat stress are born at a lower bodyweight and those deficits persist at least until puberty. In utero heat stress reduces passive transfer and calf survival. Late gestation heat stress programs a phenotype with lower milk yield, relative to herd mates born to cooled dams, in the first lactation and subsequent lactations.
