Abstract

Abstract: During the perinatal period, decreased dry matter intake, increased nutritional requirements of the rapid growth fetus in late gestation and the synthesis and secretion of milk in early lactation result in energy metabolism disorder of dairy animals. Energy metabolism disorders can cause a variety of metabolic and inflammatory diseases, which have a significant negative impact on the performance and reproduction of dairy animals. Rumen protected glucose (RPG) is less affected by the rumen microbes during digestion and can be efficiently absorbed within the small intestine, thereby providing a safe and efficient energy source to alleviate energy metabolism disorder of dairy animals during the perinatal period. This paper summarizes the physiological metabolism characteristics during perinatal period, reviews the effects and mechanisms of RPG on energy metabolism, milk yield, milk composition, oxidative stress, immunity and inflammation of perinatal dairy animals, and briefly summarizes the bioavailability of different type of RPG, in order to provide reference for the research and application of RPG in perinatal dairy animals.

Key words: rumen-protected glucose, perinatal period, dairy animals, physiological metabolism, nutritional regulation
