PARALLEL SESSION 6C: POULTRY AND PORK PRODUCTION SYSTEMS 8 th Int. Conference on LCA in the
Agri-Food Sector, 1-4 Oct 2012
Table 1. Production characteristics and ecological impacts of existing egg production systems with and without
three ethical requirements (i.e. loose hen housing, outdoor access, and limited use of external resources),
mitigation housing (i.e. replace single-tiered with multi-tiered housing), and diet (i.e. replace imported with
regional diet ingredients in percent relative to battery cage egg production).
