Energy 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 کاملNet Phosphorus Requirements of Dorper×Thin-tailed Han Crossbred Ram Lambs
A comparative slaughter trial was conducted to estimate the phosphorus (P) requirement for maintenance and growth of crossbred lambs of Dorper with a Chinese indigenous sheep breed, thin-tailed Han sheep. Thirty-five Dorper×thin-tailed Han crossbred, noncastrated ram lambs (20.3±0.22 kg of shrunk body weight (SBW)) were used. Seven lambs were randomly chosen and slaughtered at 20 kg SBW as the ...
متن کاملAssessment of dietary vitamin D requirements during pregnancy and lactation.
Concerns about vitamin D have resurfaced in medical and scientific literature because the prevalence of vitamin D deficiency in the United States, particularly among darkly pigmented persons, has increased. The primary goals of this review were to discuss past and current literature and to reassess the dietary reference intake for vitamin D in adults, with particular focus on women during pregn...
متن کاملEnergy and nitrogen metabolism of rabbits during pregnancy, lactation, and concurrent pregnancy and lactation.
1. In an experiment twenty-four cross-bred does were used, six in each of four physiological states: non-pregnant (NP), pregnant (P), lactating (L) or concurrently pregnant and lactating (CPL). They were offered a diet of high nutrient density (crude protein (nitrogen x 6.25) 272 g/kg dry matter (DM), metabolizable energy 15.5 MJ/kg DM) at one of two intakes on a scale based on metabolic body-w...
متن کاملOutbreak of primary pregnancy toxemia in fat tailed ewes due to ultrasonographic misdiagnosis of pregnancy
Four fat-tailed ewes from an indoor flock (n=40) were examined for recumbency and depressive nervoussigns. They were from a seemingly nonpregnant group of the flock that had been diagnosed bytransabdominal ultrasonography. The ration consisted of mainly wheat straw since their separation from thepregnant group. Detection of pregnancy on abdominal palpation along with depressive nervous signs an...
