Sensibilité des élevages bovins et ovins viande aux aléas selon la place des prairies dans les systèmes fourragers

Abstract : Are bovine and ovine farms whose system integrates forage crops and temporary grassland less susceptible to climatic hazards than systems that essentially rely on permanent pasture? In order to reply to this question, the technical and economic results of 3,214 farms x years (distribution of farms nationwide, 2000-2009 period) were analyzed. Variations (global variability in correlation with climatic hazards) in grass production were also examined. Results show that forage crops minimize variations in the quantity of harvested forage when grass production is exposed to hazards, however the overall variability for grassland-based systems is not significantly different than that for other systems. On the other hand, variability in grass production was higher for temporary grassland. These results must be put into perspective based on pedoclimatic potential and type of animal production for each type of forage system.
