Considerable progress has been made in understanding the protein and amino acid (AA)
nutrition of dairy cows. The chemistry of feed crude protein (CP) appears to be well …

The transition period of dairy cattle is characterized by a number of metabolic, endocrine,
physiologic, and immune adaptations, including the occurrence of negative energy balance …

The onset of lactation in dairy cows is characterized by severe negative energy and protein
balance. Increasing Met availability during this time may improve milk production, hepatic …

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 …

The periparturient period is the most critical phase in the productive cycle of dairy cows and
is characterized by impairment of the immune system. Our objective was to evaluate the …

Coordinated changes in energy metabolism develop to support gestation and lactation in
the periparturient dairy cow. Maternal physiology involves the partitioning of nutrients (ie …

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 …

Recent studies have suggested that dietary rumen-protected choline (RPC)
supplementation can modulate immune function, attenuate inflammation, and improve …

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

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