Calcium and Bone Mineral Supplement for Horses Grazing Oxalate-containing Pastures Cal-XTRA is formulated as a critical supplement for horses grazing in regions with oxalate-containing grasses, commonly in Queensland, The Northern Territory and parts of New South Wales and Victoria. Tropical and sub-tropical grass, particularly setaria, para, buffel, teff, pangola, kikuya, couch grass and green panic, contain oxalates which bind up and reduce the absorption of calcium, resulting in calcium deficiency which can lead to bone weakness. Cal-XTRA is a concentrated source of bone minerals, especially calcium, to ensure extra supply and help prevent bone demineralisation that would otherwise lead to lameness, osteoporosis and Big Head. Horses on high grain diets also benefit from the calcium and other nutrients supplied by Cal-XTRA to help bone strength and soundness during moderate to intense training. Our Concept for Cal-Xtra Kohnke’s Own Cal-XTRA is the result of more than 12 years of research and field trials by equine veterinarian and horse nutrition authority Dr John Kohnke, especially in the areas where horses are known to have poor calcium uptake and Big Head. Cal-XTRA is highly concentrated and contains more palatable forms of calcium compared to ‘chelated’ calcium supplements, making it a superior and more economical choice. It is scientifically formulated to protect calcium absorption in the presence of oxalates through a stable coating technology which shields calcium from oxalate binding with a specialised micro-coating process. This allows optimum calcium uptake to ensure bone strength and soundness, even when horses are grazing tropical grass pastures.
