Abstract
The employment of ozone in livestock production as a means of mitigating ammonia is used for enhancing air quality within animal confinement facilities, such as swine or poultry barns. Ammonia is a byproduct of animal excrement. Elevated ammonia concentrations can adversely affect the well-being of both animals and humans. The aim of this thesis was to investigate the effects of Ozone Technology Machine Unit (OTMU) utilization in poultry barns regarding ammonia concentration and its potential benefit in terms of broilers performance and welfare. In recent years, there has been a significant boom in technological advances. New devices that help mitigate the concentration of ammonia in poultry production must be developed to help improve production in a sustainable way, protecting the workers who are dedicated to this field and improving the welfare of birds. Chapter I provides the whole thesis introduction. Chapter II provides a literature review on ammonia concentration effect on broilers performance and a brief overview of the ozone utilization in livestock. Chapter III comprises a study conducted to assess if the OTMU under research improves air quality, reduces ammonia concentration within the poultry barn, ameliorates bird welfare, and boosts broilers performance.
