The milk production today calls for feeding strategies, which has the potential to increase both milk production and welfare of the cows. An individual cow concentrate strategy could potentially optimize production and welfare of dairy cows, as the ration can be adjusted according to the requirements of each cow. Implementation of individual feeding in the herd will lead to frequent adjustments in concentrate allowance; thus, it is decisive to understand how cows respond during adjustments in the feed ration.

This thesis contributes to the understanding of how dairy cows respond to frequent adjustments in concentrate allowance, and how this affects the production and the daily time budget of the cows during the entire lactation.
