In regions where intensive animal production is found, the management and disposal of manure directly affects the extent and the risk of water pollution by nitrates and air pollution by ammonia. As an alternative or complement to the treatment of effluents, solutions have been sought to reduce nitrogen pollution at its source of production. One approach that has been pursued has been to better adapt protein available in feeds to animal needs. In the context of the reformed CAP, this paper presents an evaluation of the cost of such a preventive approach to nitrogen pollution control. The results show that the CAP reform has introduced important modifications in the formulation of feed rations. A 1 to 1.5 point reduction in the protein conten...
