Grass intake while grazing has been a large unknown factor in feeding strategy of dairy cows. Within the Amazing Grazing project, during the grazing season of 2019 grazing activity of the herd of 5 farms was recorded. Sensors were used to estimate daily grass intake per herd during the period cows were in the paddock. A pilot was performed to test (1) whether it was possible to collect all required data and calculate the estimated grass intake at herd level on a daily basis and (2) to find out how the farmers experienced this parameter in terms of reliability, accuracy, availability and added value in their management. Overall the added value was acknowledged by the farmers and further development was encouraged.
