Thesis Abstract

Abstract
The dairy industry plays a crucial role in the global economy and food supply chain. Maintaining the health and productivity of dairy cows is essential for ensuring the sustainability and profitability of dairy operations. One key aspect of dairy cow health is gut health, which influences nutrient absorption, immune function, and overall well-being. Probiotics, live microorganisms that confer health benefits to the host when administered in adequate amounts, have gained attention as a potential strategy to improve gut health in dairy cows. This thesis investigates the impact of probiotics on gut health in dairy cows, with a focus on understanding the mechanisms of action, effectiveness, and practical applications of probiotic supplementation in dairy cow management. Chapter One provides an introduction to the topic, presenting the background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definitions of key terms. The introduction sets the stage for investigating the role of probiotics in enhancing gut health and overall performance in dairy cows. Chapter Two presents a comprehensive literature review on probiotics and gut health in dairy cows. This chapter explores the existing body of knowledge on the mechanisms of probiotic action, the impact of probiotics on gut microbiota composition, immune function, nutrient utilization, and health outcomes in dairy cows. The literature review synthesizes current research findings and identifies gaps in knowledge that warrant further investigation. Chapter Three outlines the research methodology employed in this study. The chapter describes the experimental design, sampling procedures, probiotic intervention protocols, data collection methods, and statistical analyses used to evaluate the impact of probiotics on gut health parameters in dairy cows. This chapter provides a detailed overview of the research approach and procedures followed to generate reliable and valid results. Chapter Four presents a detailed discussion of the findings from the study. The chapter analyzes the effects of probiotic supplementation on gut health indicators, including gut microbiota composition, immune responses, nutrient absorption, and overall health status in dairy cows. The discussion explores the implications of the study results in the context of dairy cow management and offers insights into the practical applications of probiotics in improving gut health and performance outcomes. Chapter Five offers a conclusion and summary of the key findings and implications of the study. The chapter highlights the contributions of the research to the field of animal science and dairy cow management, discusses the practical implications of the findings for dairy farmers and industry stakeholders, and suggests avenues for future research in this area. In conclusion, this thesis contributes to the growing body of knowledge on the use of probiotics to enhance gut health in dairy cows. By investigating the impact of probiotics on gut microbiota composition, immune function, and overall health outcomes in dairy cows, this study provides valuable insights into the potential benefits and practical applications of probiotic supplementation in dairy cow management. The findings of this research have implications for improving the health, productivity, and sustainability of dairy operations, ultimately benefiting both dairy farmers and consumers.
