Abstract
Histomonas meleagridis is a parabasalid protozoan and the causative agent of histomonosis, or blackhead disease, in turkeys. Withdrawal of the last remaining in-feed arsenical from the market in 2015 led to the re-emergence of the disease. As a result, there is a need to investigate alternatives, such as dietary inclusion of postbiotic and phytogenic compounds, to reduce H. meleagridis transmission and disease severity in commercial turkey flocks. The purpose of this project was to evaluate the influence of dietary inclusion of three different combinations of postbiotic and phytogenic compounds on H. meleagridis transmission in turkey poult hens. A thesis introduction has been provided in Chapter 1. A comprehensive literature review has been included in Chapter 2. Chapter 3 includes results from the in vivo study.
