[Studies on serum Mg and Ca levels in cattle with grass tetany on hypocalcemia before and following infusion with high Mg and medium or high Ca concentrations].
Behaviour of Mg and Ca content in the blood serum of 28 cattle with grass tetany and hypocalcaemia was evaluated at short time intervals after infusion of 500 ml of a solution A (containing 12 g Mg-adipat and 5 g Ca-gluconate/100 ml aqua dest.) and a solution B (containing 12 g Mg-adipate and 12 g Ca-gluconate/100 ml) respectively. After treatment with the last-named solutions there was evident a considerable increase of Mg-values in the blood serum for a longer period (up to 6 h), also in the case of distinct hypomagnesaemia while Ca-values of the circulating blood declined more quickly. Efficacy of treatment was the better the earlier infusion was performed after occurence of clinical signs. Application of solution B for treatment of grass tetany and paresis with tetany like symptoms is recommended for several reasons. Necessity of assurance the Mg and Ca supply after infusion is emphasized.
