The calculation of 
fructan risk is based on the latest scientific findings about fructans in grass. Fructans are sugar polymers found in certain types of grass and can cause health issues in horses, especially in those sensitive to high fructan levels.
To accurately assess the fructan risk, we consider various weather factors that influence fructan production:
1. Precipitation in Recent Days
Rain can affect the fructan concentration in grass by promoting plant growth, which can lead to changes in fructan levels.
2. Average Night Temperature
Cool nighttime temperatures can result in increased fructan storage in grass, as plants consume less energy at night and store more sugars.
3. Current Weather Forecast
The forecast provides insights into how weather conditions might develop in the coming days, affecting the fructan risk.
Our system continuously analyzes these factors and provides a risk assessment that enables animal owners to make informed decisions about their horses' grazing times and minimize potential health risks.
