Endogenous Faecal Phosphorus (EFP) pada Domba Menyusui yang Mengalami Defisiensi Phosphorus Kronis

Endogenous phosphorus loss in ruminants: A review

Phosphorus (P), a major mineral in animal nutrition is currently a focus of the livestock industry. This is because of its high fecal excretion by livestock and the subsequent environmental pollution, especially in the eutrophication of lakes and surface water. Areas of intensive animal husbandry and dairy farms where P is fed in excess are particularly affected. Ruminants must be fed according...

Phosphorus.

The effects of phosphorus depletion, and of calcium and phosphorus intake, on the endogenous excretion of these elements by sheep.

I . Injections of and 45Ca were used to study the influence of phosphorus depletion and repletion on the rates of endogenous calcium and P excretion in fifteen P-depleted and eighteen control sheep. 2. When given adequate P, there was a marked increase in the rate of excretion of metabolic faecal P in sheep which previously had been depleted. In control sheep a decrease was found in metabolic f...

Estimation of true phosphorus digestibility and endogenous phosphorus loss in growing chicks fed conventional and low-phytate soybean meals.

This study evaluated regression of total P output against dietary P intake to simultaneously estimate endogenous P loss and true P utilization in broiler chicks. Soybean meal (SBM) served as the model ingredient, and a comparison was made between conventional and low-phytate SBM varieties. These feedstuffs were chosen to minimize nutritive differences to dietary phytate content. Low-phytate SBM...

Phosphorus Requirements

This fact sheet has been developed to support the implementation of the Natural Resources Conservation Service Feed Management 592 Practice Standard. The Feed Management 592 Practice Standard was adopted by NRCS in 2003 as another tool to assist with addressing resource concerns on livestock and poultry operations. Feed management can assist with reducing the import of nutrients to the farm and...
