Utilisation of cut and grazed fields is linked to their geographical characteristics in mountainous bovine systems

Abstract

The impact of geographical characteristics on the utilization of cut and grazed fields was investigated on 72 farms in Massif Central (France) managing milked cows with their calves. Principal component and hierarchical cluster analyses were performed on 679 cut and grazed fields. Relationships between the classes obtained and the slope, area, distance to farmstead and elevation of the field were established through linear mixed models. The population was separated into six utilisation classes characterized by different types of sequences: one grazing before cutting, early cutting before grazing, late cutting before grazing, grazing cutting and grazing sequence, two cuttings before grazing, and one unspecialised sequence of cutting and grazing. The fields grazed before cutting are larger and closer to the farmstead than the fields cut before grazing. Elevation is involved in the orientation between early and late cutting. The fields grazed twice have a low distance to farmstead that is consistent with two periods of grazing. Although field utilisation is strongly driven by its geography, farmers have the possibility to adapt their conducting on fields with characteristics suitable for several utilisations. These results will help to model the forage system functioning and to adapt onfarm advice to the fields’ characteristics.
