Effects of Low and High Dietary Phosphorus and Acute High Dietary Phosphorus on Phosphorus Absorption in Nephrectomized Male Rats

2020
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 and Bone Disease

2017
The 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.

Dietary phosphorus depletion in sheep:

Journal of Animal Physiology and Animal Nutrition, 1990
ZusammenfassungDie 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, 1991
The 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

1978
It 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.

Maintenance requirements of phosphorus and absorbability of dietary phosphorus in sheep

The Journal of Agricultural Science, 1983
The factorial approach to the determination of the dietary requirements of macroelements is a two-stage process; in the first the net requirements are estimated and in the second, the fractional absorption of the dietary mineral is used to convert net to dietary requirements (Agricultural Research Council, 1965).

Dietary phosphorus and water quality

2017
There is a direct relationship between phosphorus levels in dairy cattle rations and the amount of phosphorus excreted in manure. Phosphorus accumulates in surface water and can pollute ponds, streams and lakes.

Dietary Calcium and Phosphorus Levels for Weanling Swine

Journal of Animal Science, 1982
Two experiments were conducted, involving 440 weanling pigs, to determine the dietary Ca and P requirements from 7 to 20 kg body weight. All diets were formulated to 20% protein from corn and soybean meal; dicalcium phosphate and limestone were used as the inorganic mineral sources with the amounts varied to meet the total dietary concentration of ...
