Climate change adaptation in mixed pigs-beef cattle sustems in grasslands areas: key role of organic

Résumé

Global climate change may increase the frequency and severity of drought periods which may potentially strongly reduce grass yields due to reduced water and nutrient availability in soils. In this context, the grassland management is essential to ensure the fodder autonomy in cattle farms. Several studies showed that multi-species livestock farming (in particularly, sheep and cattle) increases the resource-use efficiency. However, the potential benefits of systems combining pigs and cattle are less studied. We can suppose that the careful management of the different types of manures may limit variation in plant productivity and, more particularly, grass yield due to climate changes. Our objective was to develop a comprehensive analysis of mixed pigs-cattle farming systems in the French Massif Central area in order to outline and discuss potential benefits and limitations of using different manures to fertilise grasslands and crops. Two studies were performed. Firstly, on-farm 40 surveys were carried out in order to characterize how pigs and cattle effluents were used as organic fertilisers. Most farmers assigned specific fertiliser properties according to each type of effluent. For example, for most farmers, the livestock slurry promotes a rapid growth of grass whereas the application of solid manure enhance organic matter enrichment in soil. Slurry is applied to grass pastures in the spring and solid manure preferentially before the sowing date of cereals. A second survey was carried out on 20 mixed pigs-beef cattle farms which were located in a same pedoclimatic area (North of the French Massif Central) to analyse the variations in fertilisation management of grassland between the last 3 years. This study provided more precise knowledges about the pig manure application as organic fertiliser. Also, farmers seemed aware of the interest of pig slurry in the grassland management in extensive livestock production systems in order to limit variations in grass yields due to climate changes.
