The present review focuses on methyl donor metabolism and nutrition in the periparturient
and lactating dairy cow. Methyl donors are involved in one-carbon metabolism, which …

Dairy cattle undergo dramatic metabolic, endocrine, physiologic and immune changes
during the peripartal period largely due to combined increases in energy requirements for …

The periparturient period is one of the most challenging periods in dairy cows and
encompasses the 3 wk prior to and 3 wk after parturition. The nutrient requirements of dairy …

Overproduction of reactive oxygen species (ROS) is a well-known phenomenon
experienced by ruminants, especially during the transition from late gestation to successful …

Methionine (Met) plays a critical regulatory role in milk production, however, the molecular
mechanism of action of Met is largely unknown. This study therefore aimed to investigate the …

Objectives were to evaluate the effect of feeding rumen-protected methionine (RPM) in pre-
and postpartum total mix ration (TMR) on lactation performance and plasma AA …

Amino acids can enhance milk fat synthesis in bovine mammary epithelial cells (BMECs),
but the molecular mechanism is not well-known. In this study, we explored the regulatory …

Retromer is an evolutionarily conserved multiprotein complex that orchestrates the endocytic
recycling of integral membrane proteins. Here, we demonstrate that retromer is also required …

Heat stress (HS) causes reductions in milk production, but it is unclear whether this effect is
due to reduced number or functional capacity (or both) of mammary cells. Methionine …

Mastitis, inflammation of the udder, is one of the most common diseases hampering milk
yield of dairy cows. Methionine (Met) and arginine (Arg) are key nutrients with potential to …
