Wim van Ittersum (52) runs together with his wife Wolterien and children, a dairy farm with 150 dairy cows and 75 young cattle. The farmer thinks low costs and sustainability are important aspects for his company. These two issues can be found in the business operations of the farm, of which grazing is the most important link. According to the farmer this is one of the requirements for the grazing to succeed, so that there is as little delay as possible. Furthermore, the entrepreneur has arranged the plots in such a way that he never tries to get into one lot for two consecutive days.

The strategy of the farmer is based on the low costs and the sustainability of the farm. He likes to combine this with meadow bird protection.
