After exposing the main characteristics of intensive dairy farms, the authors present the advantages of rapeseed crop for these farming systems: high capability for nitrogen uptake in autumn which allows effluent spreading before winter and so gives a higher flexibility to the farmer, nutritive value of rapeseed cakes for dairy cows, positive contribution to the energetic and environmental balance at the level of the farm but also of the area. Then, the authors give the main results of an agronomic survey which has been done in the west of the France to identify the perceptions of stockbreeders concerning rapeseed crop. These data allow to know what are the questions and problems which must be solved before developing rapeseed crops in these farming systems.
Key words: nitrogen / rapeseed crop / nutritive values
