Influence of potassium on Mg- and Ca-metabolism in cows: Effects and side-effects of research [German]

摘要

Results of scientific studies are obtained by analysing Of the present knowledge of-a 'current problem and a corresponding new experimental set up. Under ideal conditions the data of the-new study agree with the deduced working hypothesis. This, general consideration is true for the well, established correlation between - K content and growth rates of plants. At low K concentrations (Up to 3 % of,dry matter) K causes a linear increase of growth, and finally a saturation. This positive effect of K,on growth rates of plants is accompanied by some side effects. There is no doubt that a high intake of K is involved in the pathogenesis Of grass tetany and of milk fever. The present publication gives some. information about this correlation and discusses the discrepancy between the intention of a scientific study and possible side effects, which cannot be predicted in many cases.
