These sources support the need to manage calcium and phosphorus supply on fodder beet diets and the use of DCP-type supplementation. They do not test this specific Agvance product or the “dusting” delivery method.

Evidence is strongest for the general approach of meeting calcium and phosphorus requirements on fodder beet-based diets and using DCP-type supplements where the diet is short. It is not specific to CalciPhos Dusting Grade.
Delivery affects consistency. With dusting over pasture or feed, individual intake can vary with feeding setup, pasture conditions and cow access, so results can differ from controlled feeding studies.
