Environmental Performance Of Feed Additives In Livestock Supply Chains Guidelines For Assessment

The production and the use of feed additives influence the environmental impact of livestock production. The use of feed additives significantly acts on feed efficiency, and thus animal and environmental performance. The methodology developed in these guidelines aims to introduce a harmonized international approach to the assessment of the environmental performance of feed additives in livestock supply chains taking into consideration the impact of their production and use all along the supply chain for large ruminants, pigs and poultry. The objective of this technical document is twofold: on the one hand, to provide detailed guidance on how to measure the environmental performance of the production of feed additives, and on the other hand, how to measure the effects of feed additives on the environmental performance of livestock products. The guidelines on the environmental performance of feed additives in livestock supply chains are intended to be used with other published LEAP guidelines.
