A preparation of a solid calcium bolus product with quick dissolution for preventing or treating hypocalcemia of dairy cows is described. Calcium chloride or the mixture with calcium propionate, calcium carbonate, calcium phosphate, calcium oxide, magnesium oxide, vitamin D, calcium acetate, calcium iodate, calcium lactate or their combination in particle or powder form with water at a weight ratio of 100 (dry ingredients) against 10 to 60 (water) into a liquid mass, pouring the liquid mass into moulds, setting at room temperature for 0.1 to 10 hours to form into a solid calcium product and sealing to avoid the effect from air moisture. The sealed cover is removed prior to use the solid calcium product as calcium bolus, which is dissolved into water within 0.5 hour.
