TL;DR: Estimates of the mixture of fuels constituting metabolizable energy in cows during the early postpartum period suggest that supply of amino acids and glucogenic compounds may be under proposed optima, whereas ketogenic and lipogenic compounds and long-chain fatty acids may be in excess.

TL;DR: Techniques of modern biochemistry promise to further understanding of the mechanisms of metabolic adaptation during the peripartal period, and to quantify the effects of nutrition and environment during pre- and postpartum periods on hepatic glucose and lipid metabolism.

TL;DR: This volume examines the raising of dairy calves, giving an account of all aspects of calf rearing from the rudiments of anatomy and development through the practicalities of feeding and housing to the period of transition from preruminant to ruminant digestion.

TL;DR: It is proposed that Y581S in ABCG2 is the causative site for this QTL, corresponding to the segregation status of all 3 heterozygous and 15 homozygous sires for the QTL in the Israeli and U.S. Holstein populations.

TL;DR: Feed restriction and ketosis resulted in previously unrecognized alterations in gene network expression underlying key cellular functions and discrete metabolic events that might help explain well-documented physiological adaptations to reduced feed intake in early postpartum cows and, thus, provide molecular targets that might be useful in prevention and treatment of liver lipidosis andketosis.
