Assessment of the impact of probiotics on the gut microbiota of broiler chickens

Thesis Abstract

Abstract
The use of probiotics in animal production has gained significant attention in recent years due to their potential benefits on animal health and performance. This thesis focuses on the assessment of the impact 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 suggested as a means to modulate the composition and activity of the gut microbiota to improve animal health and productivity. Chapter one provides an introduction to the study, presenting the background information on the use of probiotics in animal production and highlighting the significance of the study. The problem statement and objectives of the study are clearly outlined, along with the limitations and scope of the research. The structure of the thesis and key definitions of terms are also provided to guide the reader through the study. Chapter two presents a comprehensive literature review on the use of probiotics in broiler chickens, focusing on their effects on gut health, growth performance, and immune response. The review covers studies examining the mechanisms by which probiotics influence the gut microbiota and the potential benefits of probiotic supplementation in poultry production. Chapter three details the research methodology employed in this study, including the experimental design, sample collection, and analysis methods. The chapter discusses the selection of probiotic strains, dosages, and administration methods, as well as the sequencing techniques used to analyze the gut microbiota composition. Chapter four presents a detailed discussion of the findings from the study, including the impact of probiotics on the gut microbiota composition, diversity, and metabolic activity in broiler chickens. The chapter also discusses the effects of probiotics on the growth performance, immune response, and overall health of the birds. In the final chapter, chapter five, the conclusions drawn from the study are summarized, highlighting the key findings and their implications for poultry production. The study provides insights into the potential benefits of probiotics in modulating the gut microbiota of broiler chickens and improving animal health and performance. Recommendations for future research in this area are also provided. Overall, this thesis contributes to the growing body of knowledge on the use of probiotics in animal production and emphasizes the importance of understanding the complex interactions between probiotics, the gut microbiota, and animal health.
