Reproduction in Domestic Animals, Volume 58, Issue 8, Page 1097-1103, August 2023., 2023 Abstract Negative energy balance (NEB) caused by restricted feed intake leads to body condition loss (BCS), increased metabolic stress and reduced fertility in dairy cows. Propylene glycol (PG) is a precursor of ruminal propionate for gluconeogenesis used to increase metabolic adaptation to the early postpartum period.
