Abstract
The objective of this thesis was to investigate the effects of Enterococcus cecorum (EC) administration into the amnion at day 18 of embryogenesis on performance and septicemia development in broiler chickens. Chapter I consists of a brief overview of the thesis. Chapter II provides a literature review on EC-related disease in broiler chickens and methods to isolate, detect, and differentiate between commensal and pathogenic strains of EC. Chapter III consists of a study conducted to determine if different EC strains isolated from field cases that exhibited septicemia and high mortality impacted hatchability, livability, organ colonization, and early performance in broiler chickens.
