Feed phosphate for livestock

Two main studies, one for digestibility in pigs and one for broiler chickens, were conducted by SLU during the third and fourth quarters of 2021. Both compared feeds with the phosphate (RevoCaP) produced by EasyMining's Ash2Phos process and the commonly used monocalcium phosphate (MCP), measuring the amount of phosphorus in the “inputs and outputs” of the animals.  

In both studies, growth for all animals was as expected and showed no noticeable difference on any of the diets. For the pigs, the estimated total tract apparent digestibility (TTAD) of phosphorus in the RevoCaP was 60.4% and 83.8% of the phosphorus in MCP. For the chickens, the estimated ileal digestibility of phosphorus in RevoCaP was 58.4% and 75.1% of phosphorus in the MCP

The testing also shows that the RevoCaP has a digestibility that is slightly lower than MCP, but says it’s in the same range as other feed phosphates and that there are also additional parameters considered for feed phosphates, such as price, total environmental impact, CO2 emissions and use of the manure.

For the first time it’s now possible for the market to have a recycled and sustainable feed phosphate with low climate impact.
