Efficacy and tolerance of a calcium magnesium aspartate solution in hypocalcemic dairy cows

The systemic tolerance of a solution of calcium aspartate and magnesium asp artate was studied in 7 cows. Intravenously administered dosages of 500 ml per cow were well tolerated. A twofold increase of the serum calcium concen tration was measured. In 2 cows which were treated with 1000 ml of the solu tion a threefold increased calcium concentration and heart arrhythmia were found. The clinical efficacy of the solution was demonstrated in a study wi th 44 hypocalcemic cows. A long lasting increase of the serum calcium as we ll as an enhanced phosphorus concentration were measurable. In conclusion, the calcium-magnesium-aspartate solution seems to be an efficious and well tolerated alternative for the treatment of hypocalcemia in cows.
