A new study published in Poultry Science shows that while U.S. egg production has increased over the past 50 years, the industry has also been able to significantly decrease its environmental footprint. Researchers conducted a lifecycle analysis of U.S. egg production from 1960 to 2010 to evaluate environmental performance measures for the complete lifecycle from crops to hens to the farm gate. Study findings indicate that the environmental efficiencies are the result of a wide range of factors, including the reduction of natural resource use, improved hen feed, better disease control and advancements in hen housing systems.
