Feed Grade Monosodium Phosphate for Animal Feeds Supplement

Product Details

Monosodium phosphate (MSP), an inorganic feed phosphate well adapted for aquafeed

Among all phosphates, several parameters can differ, such as the P digestibility, the pH, or the calcium level.Indeed, Calcium (Ca) is an important parameter to consider. it is important for the skeleton formation and maintenance, but in excess in diet, Ca can reduce the P bioavailability by complexation (Hossain & Yoshimatsu, 2014).

Moreover, Calcium (Ca) can be absorbed directly from water via gills and intestine (Kaushik, 2005). So, to bring a phosphate source without calcium can help to balance the feed formula. Monosodium phosphate (MSP) doesn’t contain calcium compared to conventional phosphates used in aquafeed like monocalcium phosphate (MCP).

The ingredient pH should be take into account in the aquafeed formulation because dietary acidifications can increase P digestibility in trout (>+16%) (Sugiura et al., 2006) and shrimp (Piedad-Pascual, 1989; Lemos et al., 2021). Monosodium phosphate (MSP) has an acidic pH such as monoammonium phosphate (MAP) and thus contributes to the global acidification of the diet.

Lastly, it is essential to consider the water solubility and digestibility of phosphorus. Indeed, better are the P water solubility, better will be the P digestibility for fish. Monosodium phosphate (MSP) has a high P water solubility (95%) among the inorganic feed phosphates, which consequently leads to a high phosphorus digestibility in aquafeed. As an example, in trout, Morales et al., 2018 have proved that MSP has a high P digestibility (91.1%), close to MAP (92.9%).
