Aliphos® SodiPhos: A new derivative of Aliphos feed phosphates
by Aliphos, Rotterdam BV, The Netherlands
After initial laboratory testing and real scale pilot plant testing, Aliphos will bring to the market Aliphos® SodiPhos, a monosodium phosphate which will be produced in our factory in Varna, Bulgaria: content consisting of 24 percent phosphorus (P) and 19 percent sodium (Na).
Monosodium phosphate (MSP) is characterised by the fact that the phosphorus is bound to sodium, delivering a product which is almost completely water soluble (For more details see Figure one).
Solubility of phosphorus as an inorganic feed phosphate is highly correlated with its availability or better digestible phosphorus content. The higher the solubility the higher the digestibility. However, this relation is not always very strict and to assess exact phosphorus digestibility values we still have to rely on animal trials.
From literature it's known that MSP has one of the highest digestible P-content amongst the feed phosphates on the market. See, for example, the summary of the values given by the CVB-table.
Because of the fact that SodiPhos contains sodium contrary to normal feed phosphates which contain calcium (Ca), like DCP and MCP, this gives SodiPhos special application features.
SodiPhos can (partially) replace salt or sodium (Bi) carbonate in feed formulations; this can play a role in the production of broiler feeds, in which the chlorine content is limited thereby replacing salt with sodium carbonate.
SodiPhos also does not contain chlorine but is a source of highly digestible phosphorus instead. For milk cows before calving, SodiPhos can be used as a Ca-free phosphorus source. With the phosphorus instantly available for the rumen microbes, because of the high solubility, by this preventing any imbalance in rumen fermentation (See Table One).
Other uses for SodiPhos is in baby piglet feed, pet and horse food and not the least, as a highly digestible P-source for aquatic feeds. Certainly, for shrimp farming, SodiPhos (MSP) is often the product of choice, replacing MCP in the formulations because there is no demand for Ca by shrimp raised in brackish and saltwater. A high Ca-level acts even as an antagonist and decreases the P-digestibility for shrimp.
