Thesis Abstract

Abstract
The utilization of probiotics in improving growth performance and gut health of broiler chickens has garnered significant attention in recent years due to its potential to enhance productivity and welfare in poultry farming. This thesis explores the effects of probiotics on the growth performance and gut health of broiler chickens, with a focus on understanding the mechanisms underlying these effects. The study aims to investigate the impact of probiotic supplementation on key growth parameters such as body weight gain, feed conversion ratio, and mortality rate, as well as on gut health indicators including gut microbiota composition, intestinal morphology, and immune response. Chapter 1 provides an introduction to the research topic, outlining the background of the study and presenting the problem statement, objectives, limitations, scope, significance, and structure of the thesis. Chapter 2 presents a comprehensive literature review on probiotics in poultry production, covering topics such as the mechanisms of action of probiotics, effects on growth performance and gut health, and factors influencing probiotic efficacy. Chapter 3 details the research methodology, including the experimental design, sample collection and analysis methods, and statistical procedures. Key contents include the selection of probiotic strains, administration protocols, and data collection procedures. The chapter also outlines the ethical considerations and potential biases that may impact the study results. Chapter 4 presents a detailed discussion of the findings, analyzing the effects of probiotic supplementation on growth performance and gut health indicators in broiler chickens. The results of the study are interpreted in the context of existing literature, highlighting the implications for poultry farming practices and future research directions. The chapter also discusses the limitations of the study and suggests areas for further investigation. Chapter 5 concludes the thesis by summarizing the key findings and implications of the research. The study demonstrates that probiotic supplementation can significantly improve the growth performance and gut health of broiler chickens, offering a sustainable and cost-effective strategy for enhancing poultry production. The findings underscore the importance of probiotics as a valuable tool in promoting animal health and welfare in modern poultry farming systems. Overall, this thesis contributes to the growing body of knowledge on the use of probiotics in poultry production and provides valuable insights for researchers, poultry producers, and policymakers seeking to optimize animal health and productivity in a sustainable manner.
