ENVIRONMENTAL PRODUCT DECLARATION for IMPROVAC®1

feed, create less waste, and have carcasses with a greater percentage of lean meat thanbarrows. This improved effi ciency, in turn, should provide both direct and indirectenvironmental benefi ts, principally due to reductions in feed consumption and slurry(manure) generation.The scope of this Declaration is to quantify the environmental impact of Improvac use.For this reason, the whole pork meat production chain is taken into account from alife cycle assessment (LCA) perspective, covering Improvac manufacturing and pigproduction from gestation, birth, and growing through harvest. 6Although the LCA also compared the environmental burden of the Improvac system with themore traditional physical castration system, that data is not presented here, as it is out of scopein the EPD format. This comparison will be included as part of a subsequent publication.The plants and their suppliersImprovac production is based on the use of a set of specifi c substances, coming from a selectedgroup of suppliers. Specifi c data were requested from these suppliers for inclusion in the LCA. Themanufacturing plants that produce Improvac are located in the United States (Kalamazoo, Michigan),Belgium (Louvain la Neuve, Ottignies) and Australia (Parkville, Melbourne). Taking into account annualproduction on a global level, 80% of Improvac comes from Belgium, 15% from Australia, and 5% fromthe United States, to be delivered world-wide. The environmental burden of transporting the productfrom the three production facilities to the farms where it will be used has been taken into account in theanalysis calculations.5 Data about comparison between male pig and castrated pig in terms of feed conversion effi ciency are available in Pfi zer reference documents:• Meta-analyses of Pfi zer IMPROVAC ® dossier studies (preliminary analyses June 16th 2010) - Dunshea.• Impact of using vaccination with IMPROVAC ® rather than physical castration on the carcass characteristics of fi nishing male pigs.
