Resigning protein concentrates in dairy cattle nutrition: a problemor a chance?

Summary in the original language of the document

This paper is aiming to discuss significant aspects of dairy cows’ demand for dietary protein and to put these in a general context of rumen fermentation efficiency. The question is, whether new perspectives on optimal rumen functioning could be found which allow to develop reasonable low-input feed evaluation systems for dairy cattle. Besides the reduction in concentrated feedstuff these systems should enable to avoid nutrition based metabolic disorders of the cattle and to indicate advantageous side-effects coming along with low-concentrate feeding. A rough outline of research and development topics to achieve such systems shall be presented with this paper.
