Fructan is a substance that can cause laminitis. Fructan is produced by grass, to an extent that depends on weather conditions. The fructan index is compiled on the basis of the current weather information. This makes it easy to see if there is a risk of a high fructan content, allowing you to adjust the grazing time and duration of grazing. At this time we only have information from the Netherlands and Belgium but if there's enough interest, we can add measure points in other countries as well.
