Thesis Abstract

Abstract
The poultry industry is continuously seeking sustainable and effective ways to enhance livestock health and production. Probiotics, as live microorganisms, have gained attention for their potential to modulate gut microbiota and improve animal performance. This study investigated the effects of probiotics on the gut microbiota of broiler chickens, focusing on the microbial composition, diversity, and functional implications. Chapter 1 provides an introduction to the study, discussing the background, problem statement, objectives, limitations, scope, significance, and structure of the thesis. The chapter also outlines key definitions to enhance the understanding of the research context. Chapter 2 presents a comprehensive literature review, covering ten key aspects related to probiotics, gut microbiota, broiler chickens, and their interactions. This section synthesizes existing knowledge and identifies research gaps that motivate the current study. Chapter 3 details the research methodology, including the experimental design, sample collection, probiotic administration, microbial analysis techniques, statistical methods, and ethical considerations. The chapter highlights the systematic approach employed to investigate the effects of probiotics on the gut microbiota. Chapter 4 presents a detailed discussion of the findings, analyzing the impact of probiotics on the gut microbial composition, diversity, and functionality in broiler chickens. The chapter explores the implications of these changes on animal health, performance, and potential applications in the poultry industry. Chapter 5 concludes the thesis by summarizing the key findings, discussing their implications, and highlighting future research directions. The chapter underscores the significance of probiotics in modulating the gut microbiota of broiler chickens and the potential benefits for sustainable livestock production. Overall, this thesis contributes to the understanding of how probiotics can influence the gut microbiota of broiler chickens, shedding light on their potential as a sustainable approach to improve animal health and performance in the poultry industry. The findings provide valuable insights for researchers, practitioners, and stakeholders interested in enhancing poultry production through microbial modulation strategies.
