Dietary phosphorus for beef cows
American Journal of Veterinary Research, 1986SUMMARY Hereford heifers (48 initially) were individually fed variable amounts of dietary phosphorus (P) from weaning through their 8th gestation. During phase I, 2 groups (24 cows each) were given 20.6 to 38.1 g of P/day and 6.0 to 12.1 g of P/day (increasing as animals grew).

Renal tubular adaptation to dietary phosphorus
Nature, 1976THE kidney is very important in the maintenance of the overall balance of inorganic phosphate (Pi). The renal response to variations in dietary Pi has been generally explained by changes in the amount of Pi filtered by the glomerulus. When a change in the tubular Pi transport has been suspected, it has usually been attributed to an alteration in ...

Dietary Phosphorus Requirement of Channel Catfish
The Journal of Nutrition, 1982Two experiments were conducted to reevaluate the dietary phosphorus requirement of fingerling channel catfish. Basal diets containing either casein with supplemental inorganic phosphorus and 0.5% total calcium or egg albumin with supplemental inorganic phosphorus and 0.75% total calcium yielded similar requirement data.

Dietary phosphorus and kidney disease
Annals of the New York Academy of Sciences, 2013High serum phosphate is linked to poor health outcome and mortality in chronic kidney disease (CKD) patients before or after the initiation of dialysis. Therefore, maintenance of normal serum phosphate levels is a major concern in the clinical care of this population with dietary phosphorus restriction and/or use of oral phosphate binders considered to

Dietary Phosphorus, Calcium Metabolism and Bone
The Journal of Nutrition, 1993Many American women consume diets high in phosphorus and low in calcium. Concern about this dietary pattern stems from studies that show high phosphorus, low calcium intake causes secondary hyperparathyroidism and bone loss in several animal models. Recent studies in young adults have shown that a high phosphorus, moderately low calcium intake results ...

Dietary Phosphorus and Bone Disease
2017The intake of phosphorus from foods, both inorganic and organic sources, may exert an adverse effect on the homeostatic regulation of calcium as well as of phosphate if it is too high or too low. This effect is especially true when the ratio of dietary calcium to dietary phosphorus is below 0.5–1 or greater than 1.5–1.

The effects of dietary phosphorus restriction followed by acute high phosphorus load on fractional phosphorus absorption will be investigated in 72 commercial male Sprague-Dawley rats with 5/6th nephrectomy (n=36) or sham operation (n=36). This study is a 2x3 factorial design with n=12 rats assigned to one of three dietary treatment groups within each ...

Dietary phosphorus depletion in sheep:
Journal of Animal Physiology and Animal Nutrition, 1990ZusammenfassungDie Untersuchungen wurden an sechs Schafen mit einem Alter von etwa 8 Monaten bei Versuchsbeginn durchgeführt. Über eine Dauer von 38 Wochen wurden die Tiere mit einer halbsynthetischen Ration gefüttert, über die sie täglich im Mittel 0,97 g P aufnahmen.

Effects of maleic acid on renal phosphorus transport: role of dietary phosphorus
American Journal of Physiology-Renal Physiology, 1991The effects of maleic acid on renal phosphate (Pi) transport were examined by clearance and brush-border membrane vesicle (BBMV) transport studies. In normal rats, maleic acid 50 mg.kg body wt-1.h-1 increased the phosphaturia (P less than 0.001). Intraperitoneal administration of a similar dose of maleic acid decreased the BBMV uptake of Pi but not ...

Effect of Dietary Phosphorus Deprivation on Renal Handling of Calcium and Phosphorus
1978It has been shown (1–6) that chronic Pi deprivation decreases urinary Pi excretion, but increases Ca excretion, suggesting a close relationship between Ca and Pi in renal adaptation to a variation in dietary Pi intake. However, in chronic Pi deprivation, plasma concentrations of Pi and Ca, and filtered loads of these ions are altered.
