What have scientists determined in their research about the quality, nutritional charactertistics and production practices used in organic agriculture? Below are summaries of peer-reviewed studies by international scientists and researchers regarding poultry production as it relates to organic agriculture. Each link provides a summary of the background and methodology, findings, and lists the full reference for further reading. Descriptions about the scientific findings and conclusions are those of the original author, and not this project.
On this web site, the term free-range implies a system of raising animals where the animals have the freedom to move in the environment and does not necessarily imply that they meet standards for "natural" (without growth hormones and additives) or "organic" (without growth hormones, antibiotics and feed without conventional fertilizers and pesticides). When in doubt, refer to the original research.
Note that livestock feed varies among countries, and comparisons of organic and conventional systems in other countries may produce different results in the United States.
