The experiment lasted for 7 months. Feed rations were balanced according NEL system. Roughages were administrated ad libitum whereas their intake was controlled. Concentrates were standarized. The following protein components were employed in the mixed feed: group 1 - rapeseed meal; group 2 rape cake and group 3 horse bean and white lupin. Cow yield, as calculated in kg FCM was higher in group 2 in comparison to groups 1 and 3
