* Magnesium is important for muscular and nervous conduction.
*Low Mg <sup>++</sup> diets may induce acute hypo-magnesaemia in lactating cows.
** Seen as tremors and convulsions (tetany).
** For example, poor quality silage.
* High K<sup>+</sup> diets induce a relative Mg<sup>++</sup> imbalance.
** For example, lush pasture.
** Known as "grass staggers".
** Produces tetany and ataxia, and sometimes cardiac arrest.
** Only shock haemorrhages can be seen at autopsy; i.e. non-specific findings.
