| Acute neonatal hypocalcaemia results in tetany and convulsions, usually at 5 to 14 days of age. |
| Ensure that all milking cows are receiving enough magnesium and calcium in their diet to avoid grass tetany and milk fever. |
| Taking an example in practical terms, a cow down with tetany would be dead before a bottle of magnesium could be prescribed and administered. |
| Clinically significant hypocalcemia with paresthesia, tetany and hypotension may be reversed by an infusion of calcium gluconate. |
| An insufficient supply of magnesium can result in grass tetany in cows due to an insufficient amount of magnesium in the roughage. |
| Potential manifestations of hypocalcemia may include paresthesias, myalgias, cramping, tetany, and convulsions. |
