Protein metabolism during lactation.
Lactation increases considerably the demand for amino acids over that required for basal needs. The demand imposed varies with the quantity of milk produced and, between species, with the protein content of milk. Using data on milk composition from Blaxter (1989) and assuming milk production of 60, 1000 and 50 000 ml/d for a rat, human subject and dairy cow respectively, the ideal protein requi...
متن کاملAdjustments in energy expenditure and substrate utilization during late pregnancy and lactation.
BACKGROUND Metabolic adjustments occur during pregnancy and lactation to support fetal growth and milk synthesis; however, the effect of body composition and hormonal milieu on these changes is poorly understood. OBJECTIVE We hypothesized that energy metabolism changes during pregnancy and lactation to support fetal growth and milk synthesis, and that body composition and hormonal milieu infl...
متن کاملEnergy requirements during pregnancy and lactation.
OBJECTIVE To estimate the energy requirements of pregnant and lactating women consistent with optimal pregnancy outcome and adequate milk production. DESIGN Total energy cost of pregnancy was estimated using the factorial approach from pregnancy-induced increments in basal metabolic rate measured by respiratory calorimetry or from increments in total energy expenditure measured by the doubly ...
متن کاملTrade-offs in Energy Allocation During Lactation
SYNOPSIS. During lactation, mothers require energy to meet both maternal and offspring requirements. If a mother exports too much energy to dependent offspring (in milk), her weight loss may be excessive and maternal risk may increase. Conversely, too little energy allocation to offspring may reduce the growth rate or induce mortality of dependent offspring. This paradigm was evaluated in cotto...
متن کاملDiminution in energy expenditure during lactation.
Energy expenditure at rest and in response to a meal and to an infusion of noradrenaline was measured in 12 lactating women and compared with that in seven bottle feeding women and seven non-pregnant, non-lactating controls. The energy response of the lactating women was remeasured after lactation stopped. During lactation the resting metabolic rate was unaltered but there was a reduced respons...
