ABSTRACT OF THE DISCLOSURE A process for the preparation of lactosylurea and the N-methylol derivative thereof which are usable as feed supple- ments for ruminants. According to this process, lactose and urea are heated to 70 - 110°C with a minimum of water and, if possible, this water is eliminated during the reaction. The crude reaction product can be purified by grinding with ice-water or ethanol and subsequent draining so as to eliminate by dissolution in such solvants the unreacted urea. The corresponding N-methylol derivative is obtained by the reaction with formaldehyde.
