Résumé en anglais

The purpose of this study was (i) to select options for enteric methane abatement in French conditions, while maintaining production and changing practices but not systems, and (ii) to evaluate the extent of abatement and its cost from 2010 to 2030. Two options were selected: supplying unsaturated fats, and using nitrates as a dietary additive in the diet. Unsaturated fats resulted in a higher abatement, because a greater number of animals were concerned by the option, but incurred a higher total cost and a higher cost per ton of CO2-equivalent avoided. The results were sensitive to methodology, and to variations in the choice of fats and in the cost of ingredients, among other factors.< Réduire
