The invention relates to a method for improving the milk yield of dairy cows by feeding the cows with an oil seed product, especially rape seed, that has been heat treated by heating cleaned oil seeds for 20-60 minutes and with the addition of water to a temperature of 65-85 degrees Celsius to obtain a water content in the product of 10-16% and then heating for additional 20-60 minutes and with the addition of water to a temperature of 80-100 degrees Celsius to obtain a water content of 14-18% so that the fat hydrolysis of the end product with lipase for 100 minutes becomes at most 30%, whereupon the heat treated seed product, optionally after cooling, is crushed in a roller crusher where the gap between the rollers is selected between 0.3 to 1 time the seed diameter. The invention also relates to the above method for heat treatment of oil seeds and a continuously operating apparatus for performing the heat treatment.
