An essentially dry powdered preparation containing a calcium source for the prevention and treatment of calcium deficiency conditions in mammals, e.g. dairy cows, is enclosed in a substantially water soluble, dispersible or disintegrable casing mainly composed of a cellulose material such as e.g. paperboard, cardboard, millboard, or pasteboard, or a gelatinized starch material. The calcium source is preferably a mixture of calcium chloride and calcium propionate enclosed in a cylindrical paperboard or cardboard tube or a gelatinized starch shell closed at both ends, which is administered to an animal with a bolus or bullet gun. The administration is safe and clean and the powdered mixture is quickly released in the stomach or rumen without causing erosion, irritation or inflammation of the mucosa.

1. A preparation comprising a calcium source and a casing enclosing said calcium source, which preparation can be administered orally as to bolus an animal for the prevention an/or treatment of calcium deficiency in mammals, wherein (1) said calcium source isin an essentially dry and essentially non-fatty powdered form, andcomprises a compacted or compressed mixture of calcium chloride and calcium propionate containing at least 30 grams of calcium,(2) the total content of moisture or water of said powdered calcium source will not tend to dissolve or disintegrate the casing during storage and distribution of the preparation,(3) the individual particles of said powdered calcium source are not enveloped in or impregnated with any fatty or greasy substance to an extent that will hamper the calcium source from quickly dissolving or leaching into the gastric or rumen juice of an animal, when ingested, and(4)said casing is cylindrical in form and is mainly composed of cellulose or gelatinized starch material that is substantially soluble, dispersible or disintegrable in water so that the casing is capable of quickly dissolving and/or disintegrating in gastric or ruminal juice thereby exposing the calcium source to the juice. 2. The preparation according to claim 1, wherein the cellulose material is selected from the group consisting of paperboard, cardboard, millboard, and pasteboard, sized with a water soluble edible size. 3. The preparation according to claim 1, wherein the proportion of calcium chloride constitutes 10-99% by weight and the proportion of calcium propionate constitutes 90-1% by weight of the total mixture of calcium chloride and calcium propionate. 4. The preparation according to claim 1, wherein the mixture of calcium chloride and calcium propionate is in a proportion of calcium chloride of 50-95%, by weight and a proportion of calcium propionate of 50-5%, by weight of the total mixture of calcium chloride and calcium propionate. 5. The preparation according to claim 1, wherein the casing contains at least 40 grams of calcium. 6. The preparation according to claim 1, further comprising a magnesium compound. 7. The preparation according to claim 1, further comprising a magnesium compound selected from MgO and MgSO4. 8. The preparation according to claim 1, further comprising vitamin D3. 9. The preparation according to claim 1, in a unit dosage form adapted for administration to a mammal and in an amount sufficient for the prevention and/or treatment of milk fever (Parturient Paresis) in said mammal. 10. The preparation according to claim 9 in a form and quantity sufficient for prevention and/or treatment of milk fever (Parturient Paresis) in a ruminant. 11. The preparation according to claim 10, in a form and quantity sufficient for prevention and/or treatment of milk fever (Parturient Paresis) in a dairy cow. 12. The preparation according to claim 1, wherein the cellulose material is paperboard, cardboard, millboard, or pasteboard. 13. The preparation according to claim 1, wherein the cylindrical casing is in the form of a tube and is provided with at least one weakened line circumferentially around its periphery in the form of a rolled or cut grove or an array of perforation points or narrow circumferential slots. 14. The preparation according to claim 1, wherein the cylindrical casing is in the form of a cylindrical tube and is closed at each end with a cap or a disc of cellulose or gelatinized starch material, and a rim at the one end of the cylindrical tube is bent or beaded inwards so as to provide a rounded outer end and an inner head or ledge on which an internal placed circular dosing disc abuts, whereas the other end of the cylindrical tube is closed by a circular disc inserted into the bore of the tube and attached therein with wax, paraffin or water soluble glue. 15. The preparation according to claim 1, wherein the cylindrical casing is in the form of a cylindrical tube and is closed at each end with a cap or a disc of cellulose or gelatinized starch material, a rim at the one end of the cylindrical tube is bent or beaded inwards so as to provide a rounded outer end and an inner bead or ledge on which an internal placed circular closing disc abuts, whereas the other end of the cylindrical tube is closed by a circular disc inserted into the bore of the tube and attached therein with wax, paraffin or water soluble glue, and the cylinder is provided with at least one weakened line circumferentially around its periphery in the form of a rolled or cut grove or an array of perforation points or narrow circumferential slots. 16. A preparation in a unit dosage form capable of and adapted for administration to a mammal, and comprising a calcium source and a casing, wherein (1) the calcium source is adapted to and capable of being administered orally as a bolus to a mammal, the calcium source being present in an amount sufficient for the prevention and/or treatment of calcium deficiency in the mammal,(2) the calcium source is in an essentially dry powder form, essentially free of any fatty or greasy substance,(3) the calcium source is enclosed in a substantially water soluble, dispersible or disintegrable cylindrical casing mainly composed of cellulose or gelatinized starch material,(4) said casing is a cylindrical tube closed at both ends with a cap or disk of cellulose or gelatinized starch material;(5) the calcium source comprises a compacted or compressed dry powder mixture of calcium chloride and calcium propionate containing at least 30 grams of calcium,(6) the casing is capable of and adapted to quickly dissolve and/or disintegrate in gastric or ruminal juice thereby exposing the calcium source to the juice, and(7) the individual particles of said powdered calcium source are not enveloped in or impregnated with any fatty or greasy substance to an extent that will hamper the calcium source from quickly dissolving or leaching into the gastric or rumen juice of an animal, when ingested. 17. The preparation according to claim 16, wherein the mixture of calcium chloride and calcium and calcium propionate is in a proportion of calcium chloride of 50-95%, by weight and a proportion of calcium propionate of 50-5%, by weight of the total mixture of calcium chloride and calcium propionate; andthe casing contains at least 40 grams of calcium.
