La complexité des parcellaires : une contrainte ou un atout pour réduire les achats de concentrés en systèmes laitiers de montagne ?

Abstract : Dairy systems in montainous regions are often constrained by complex field patterns. The following question therefore arises: when and how do field pattern characteristics help increase feed autonomy? We studied the relationship between field patterns and feed purchases using 25 dairy farms in Auvergne, France. These farms were parsimonious in their use of concentrates. Field altitudinal diversity, field distribution, field number, and the proportion of arable land were characterized for the different farms. Large differences in concentrate purchases existed across the three categories of field patterns we identified. Several methods of increasing feed autonomy were observed; their effectiveness depended on field pattern characteristics (and notably on the proportion of arable land), as well as on the management strategies chosen by farmers.
