Comparison with limestone flour


I currently add limestone flour to the feed to aid bone formation and density. We are on clay with a high pH. How much better would Calphormin be?

  • Veterinary Advisor

Both supplements provide a good source of Calcium. However Calcium is not the only mineral integral to bone development. Calphormin contains other essential minerals to aid bone integrity so in my opinion is the better supplement. However there have not been any studies done to compare the two so I cannot quantify for you how much "better" it is than Limestone Flour. If money is not an issue then I would use Calphormin otherwise Limestone Flour will still be helpful.
