Plasma and cerebrospinal fluid (CSF) samples from field cases of grass tetany in dairy and beef cows indicate that the signs of tetany develop only in hypomagnesaemic cows that also have very low CSF magnesium levels. In dairy cows with experimentally induced hypomagnesaemic cows that also have very low CSF magnesium levels. In dairy cows with experimentally induced hypomagnesaemic tetany, a steep fall in CSF magnesium concentrations has been observed just prior to the appearance of tetany. In conscious sheep a tetanic syndrome has been produced by ventriculolumbar perfusion of the CSF space with synthetic CSF solution of low magnesium concentrations.
