Abstract
A preparation for the prevention or treatment of hypocalcemia in ruminants is prepared by forming a homogeneous mixture of CaCl.sub.2.xH.sub.2 O and CaSO.sub.4.yH.sub.2 O, x being a number greater than 0 and lower than 6 and y being a number equal to or greater than zero and lower than or equal to 2, at a weight ratio of 1:0.05 to 1:2.4, adding water to the mixture to convert the ingredients to CaCl.sub.2.6H.sub.2 O and CaSO.sub.4.2H.sub.2 O, introducing the mixture into molds, and heating the molds so that the mixture solidifies.
Claims3
A method of providing dosage units containing calcium for administering to ruminants to treat hypocalcemia, said method comprising the steps of
- (a) mixing CaCl.sub.2.xH.sub.2 O and CaSO.sub.4.yH.sub.2 O, x being a number greater than 0 and lower than 6 and y being a number equal to or greater than 0 and lower than or equal to 2, the weight ratio of CaCl.sub.2.xH.sub.2 O to CaSO.sub.4.yH.sub.2 O being from 1:0.05 to 1:2.4, to form a homogeneous mixture,
- (b) adding water to said homogeneous mixture to provide a mass which will flow through a funnel having a neck diameter of 10 mm at 40.degree. C., the amount of water not exceeding the amount needed to convert CaCl.sub.2.xH.sub.2 O to CaCl.sub.2.6H.sub.2 O and CaSO.sub.4.yH.sub.2 O to CaSO.sub.4.2H.sub.2 O,
- (c) introducing said mass into a plurality of casting moulds, and
- (d) subjecting said mass contained in said moulds to a temperature such that said mass solidifies therein into a solid mass containing a mixture of CaCl.sub.2 and CaSO.sub.4 hydrates.
