Research Project: Performance and Physiological Characteristics of Poultry Vaccinated and/or Challenged with Avian Pathogenic Escherichia coli (APEC)

Location: Poultry Research

Project Number: 6064-13000-013-006-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Jul 31, 2019
End Date: Jul 30, 2024

Objective:
To investigate and assess performance and physiological characteristics of poultry vaccinated against avian pathogenic Escherichia coli (APEC).

Approach:
Performance measurables (e.g. body weight, mortality, feed conversion, egg production) will be obtained from vaccinated and unvaccinated broiler and/or layer poultry with and without subsequent virulent challenge and comparisons among treatments will be performed. Further, posthumous examinations (e.g. histopathologic lesions, digestive and reproductive organ characteristics) of these poultry will demonstrate avian pathogenic Escherichia coli (APEC) associated disease ramifications and assess protection afforded by vaccines.
