When a quantity of fodder (7) is to be removed from a stock (1) thereof, fodder is separated from the stock by removing means (2,3) and placed into a container (11). A specific weight of fodder (7) is to be separated in one or more operations of the removing means (2,3). To that end, the volume of the quantity of fodder that is to be separated or that has been separated is determined. The weight can then be determined on the basis of the volume that is to be separated or that has been separated.
