The clinical symptoms that can be observed in the cows in question correspond to the few, old literature references on the subject of iatrogenically induced magnesium poisoning as well as those of nervous ketosis. However, the present cases of hypermagnesemia are not iatrogenic but most likely of nutritional origin, as severe hypermagnesemia is found in all animals in the herd.

The occurrence of acute magnesium intoxication of non-iatrogenic origin, which has not yet been reported in the literature, and of course the occurrence of acute central nervous attacks in adult cattle make the illnesses of the cows on this farm appear particularly important, so that this problem is of practical and scientific interest . In addition to further blood chemistry tests on the farm's cattle, the magnesium load in the feed chain is to be determined.

After receiving the results of a representative number of soil, water and feed analyses, the animal's individual magnesium load can be determined using ration calculations. The magnesium content in the cows' milk is also recorded.
