Thesis Abstract

Abstract
This thesis investigates the impact of probiotics on the gut microbiota of broiler chickens. The study aims to explore how the administration of probiotics influences the composition and diversity of the gut microbiota in broiler chickens, with a focus on identifying potential benefits for poultry health and production. The research is structured into five main chapters. Chapter 1 provides an introduction to the study, including the background of the research, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of terms. Chapter 2 presents a comprehensive literature review covering ten key aspects related to probiotics, gut microbiota, broiler chickens, and their interactions. Chapter 3 details the research methodology, including study design, sample collection, probiotic administration protocols, DNA extraction, sequencing, and data analysis methods. In Chapter 4, the findings of the study are extensively discussed, focusing on the changes observed in the gut microbiota composition and diversity following probiotic supplementation. The discussion also includes the potential implications of these changes on broiler chicken health, growth performance, and overall well-being. Furthermore, the chapter explores the mechanisms through which probiotics may exert their effects on the gut microbiota and the host. Chapter 5 serves as the conclusion and summary of the thesis, highlighting the key findings, implications, and contributions to the field of animal science. The study provides valuable insights into the potential benefits of probiotics in modulating the gut microbiota of broiler chickens, thereby enhancing their health and performance. Additionally, the research sheds light on the importance of understanding the intricate relationship between probiotics, gut microbiota, and host health in poultry production. Overall, this thesis offers a comprehensive investigation into the impact of probiotics on the gut microbiota of broiler chickens, contributing to the growing body of knowledge on the potential applications of probiotics in improving animal health and production outcomes.

Thesis Overview

The project titled "Exploring the impact of probiotics on the gut microbiota of broiler chickens" aims to investigate the effects of probiotics on the gut microbiota of broiler chickens. The gut microbiota plays a crucial role in the overall health and performance of poultry, and probiotics have been increasingly recognized for their potential to modulate the gut microbiota and improve animal health. The research will begin with a comprehensive literature review to establish the current understanding of the gut microbiota in broiler chickens and the potential benefits of probiotics in poultry production. This review will cover topics such as the composition of the gut microbiota, the role of probiotics in animal health, and previous studies exploring the use of probiotics in poultry. The methodology section of the research will outline the experimental design, sample collection, and laboratory techniques that will be employed to evaluate the impact of probiotics on the gut microbiota of broiler chickens. This section will include details on the selection of probiotic strains, the administration method, and the parameters used to assess changes in the gut microbiota composition. The findings of the research will be presented and discussed in detail in the results and discussion section. This section will highlight any significant changes observed in the gut microbiota of broiler chickens following probiotic supplementation. The discussion will also address the implications of these findings for poultry production and animal health. In conclusion, the research aims to contribute to the existing knowledge on the use of probiotics in poultry production and their impact on the gut microbiota of broiler chickens. By exploring the potential benefits of probiotics in modulating the gut microbiota, this research seeks to provide valuable insights for improving the health and performance of broiler chickens in commercial production settings.
