In order to get the rumen microbes used to the new feed situation, a gentle change in feed is required. With the help of manure screening, a tool is to be created to monitor the gentle change in feed on site at the farm. In addition, this experiment is intended to clarify whether there are differences in the conversion phase between the short-grass pasture and paddock pasture systems. The results of this study should make it easier for newcomers to grazing as well as grazing professionals to switch feed.
