Eight Finncattle cows were used in two replicated 4x4 Latin squares with 21 -day periods to study the effects of replacing rapeseed cake with linseed cake in proportions of 0, 1/3, 2/3 and 1 (on air dry basis), the total amount of supplement being 1.5 kg/day (on air dry basis). The basal diet consisted of silage fed ad libitum and a 4.5 kg/day (on air dry basis) barley:oats (1:1) mixture. The experimental diets had no effect on feed intake. Effective protein degrability (EPD) determined by the nylon bag method was higher for linseed cake than for rapeseed cake. Milk production decreased linearly (P
