Abstract

The objective of this study was to examine the potential of digestibility improving enzymes to reduce greenhouse gas (GHG) emissions in broiler production. The product examined was a new enzyme called Axtra XAP, developed by DuPont, Danisco Animal Nutrition. Two scenarios were compared: one where Axtra XAP was not included in the diet and one where Axtra XAP was included in the diet. Axtra XAP facilitated higher inclusion rates of cheaper (and possibly more environmentally friendly) feed ingredients that have a lower nutritional value in the diet. Axtra XAP’s environmental improvement potential was documented through a Life Cycle Assessment (LCA) by applying a consequential approach including indirect land use changes (ILUC). The findings showed that Axtra XAP could reduce GHG emissions from broiler production by 5%. A sensitivity analysis was conducted to assess the robustness of the results and it showed that the result varied substantially. The most important parameters were the inclusion or exclusion of ILUC and changes in the feed formulation.
