MAG26, our magnesium phosphate
MAG26,our magnesium phosphate, was launched by Phosphea in 1994 in Saint-Malo factory in France where it is still produced.
Registered in the Feed Materials catalogue, it contains 14% Phosphorus and 26% Magnesium. It is the result of the chemical reaction between phosphoric acid and a source of magnesium. This is a stable product over time which meets the requirements of feed manufacturers.
The magnesium phosphate, MAG26, is available in two particle sizes: in mini-granules (0.2 – 1.25 mm) and in semi-granules (0.5 – 1.8 mm).
Suitable for ruminants
MAG26, Phosphea’s magnesium phosphate, is suitable for ruminants as it brings a high available source of magnesium (Mg) in granules and phosphorus (P). The intrinsic pH of MAG26, combined with a progressive release of phosphorus (Pse>20%) in the rumen, gives it an interesting buffering capacity which allows to improve ruminal fermentations.
As MAG26 brings 26% of high available Mg, it contributes to reduce the risk of hypomagnesemia and hypocalcemia during the dry period. Offering a reactivity 2 times to 4 times lower than an MCP and MgO mixture, it can partially replace both MCP and MgO of premixes and minerals formulas.
A magnesium phosphate that improves fiber digestibility:
MAG26 is a feed phosphate that contains phosphorus (P=14%) and magnesium (Mg=26%). Thanks to its combination of P and Mg, MAG26 improves ruminal function. MAG26 also contributes to deal with technological constraints. Phosphea recommand this magnesium phosphate solution during dry period and early lactation.
Available source of P:
MAG26 contains 14% P with a Pse > 20%. MAG26 is the feed phosphate with the best relative biological value (RBV) in ruminants (101%). The in vitro study conducted with Groupe Roullier Research Center (CMI) in 2019, revealed a distinctive behavior of MAG26 compared to other phosphates. Indeed, under ruminant conditions, the phosphorus (P) of MAG26 magnesium phosphate is progressively released over time. However, the phosphorus requirement of bacteria is 2 times higher than the maintenance requirement of the cow (Meschy, 2007). This positive release of P thus favored rumen microbial activity.
Available source of Mg:
MAG26 contains 26% magnesium highly available to the animal (RBV 86%). Compared to a calcium phosphate, the magnesium phosphate MAG26 has an alkalinizing effect, which allows to regulate the ruminal pH, thus reflecting the interest of combining this phosphate with a buffer solution. This combination of phosphorus and magnesium provides a favorable environment for ruminal fermentations.
MAG26 allows to reduce reactivity mineral mixture:
Compared to formulas containing monocalcium phosphate (MCP) and magnesium oxide (MgO), MAG26 – used alone or in combination with feed phosphate or MgO – is able to reduce the reactivity of your mineral mixtures.
The main benefits of Phosphea’s magnesium phosphate MAG26:
Highly available source of P and Mg … but without Ca.
Improves ruminal fermentations and more precisely, fiber digestibility.
Has a synergistic alkalizing power with buffer solutions.
Decreases the reactivity of mineral mixtures compared to MCP + MgO.
