Thesis Abstract

Abstract
The utilization of probiotics in enhancing gut health and performance in broiler chickens has gained significant attention in recent years due to its potential benefits in improving poultry production efficiency and reducing the need for antibiotics. This thesis aims to investigate the effects of probiotics on gut health and performance in broiler chickens through a series of experiments and analyses. The introduction section provides a background of the study, highlighting the importance of gut health in poultry production and the potential of probiotics as a natural alternative to antibiotics. The problem statement identifies the challenges faced in modern poultry farming, including antibiotic resistance and gut health issues, which necessitate the exploration of alternative solutions. The objectives of the study are outlined to evaluate the impact of probiotics on gut health parameters, growth performance, and immune response in broiler chickens. The literature review chapter explores existing research on probiotics in poultry production, discussing the mechanisms of action, benefits, and potential challenges associated with their use. Various studies on the effects of probiotics on gut health, nutrient absorption, and immunity in broiler chickens are critically analyzed to provide a comprehensive understanding of the topic. The research methodology chapter details the experimental design, sample collection, and analytical techniques used in the study. Specific methods for administering probiotics, measuring gut health parameters, and assessing performance indicators in broiler chickens are described to ensure the validity and reliability of the results. In the discussion of findings chapter, the results of the experiments are presented and interpreted in relation to the research objectives. The effects of probiotics on gut microbiota composition, nutrient digestibility, growth performance, and immune response in broiler chickens are discussed, highlighting the potential benefits and limitations of probiotic supplementation. The conclusion and summary chapter provide a comprehensive overview of the key findings and implications of the study. The significance of the results in improving gut health and performance in broiler chickens is discussed, along with recommendations for future research and practical applications in poultry production. Overall, this thesis contributes to the growing body of knowledge on the utilization of probiotics in enhancing gut health and performance in broiler chickens, offering valuable insights into the potential benefits of probiotic supplementation as a sustainable and effective strategy in modern poultry farming practices.

Thesis Overview

The research project titled "Utilization of probiotics in enhancing gut health and performance in broiler chickens" aims to investigate the impact of probiotics on the gut health and overall performance of broiler chickens. This study is motivated by the growing interest in alternative strategies to improve poultry health and productivity, considering the increasing concerns over antibiotic resistance and consumer demand for safer food products. Probiotics, as live microorganisms that confer health benefits when administered in adequate amounts, have shown potential in promoting gut health and enhancing performance in various livestock species. The research will begin with a comprehensive review of the existing literature on probiotics and their effects on gut health and performance in broiler chickens. This literature review will encompass studies on the mechanisms of action of probiotics, their potential benefits in poultry production, and any limitations or challenges associated with their use. By synthesizing this information, the research aims to identify gaps in knowledge and establish a foundation for the empirical investigation. The empirical phase of the study will involve conducting experiments to evaluate the effects of specific probiotic strains on the gut health parameters and performance metrics of broiler chickens. This will include assessing factors such as gut microbiota composition, intestinal morphology, nutrient digestibility, growth performance, and immune responses in birds supplemented with probiotics compared to control groups. The research design will incorporate appropriate controls and statistical analyses to ensure the validity and reliability of the results. Furthermore, the study will explore the potential mechanisms through which probiotics exert their effects on broiler chickens, such as modulating the gut microbiota, enhancing nutrient absorption, stimulating immune responses, and promoting overall gut health. Understanding these mechanisms is crucial for elucidating the biological basis of probiotic action and optimizing their use in poultry production. The findings of this research are expected to contribute valuable insights into the role of probiotics in enhancing gut health and performance in broiler chickens. By elucidating the mechanisms of probiotic action and identifying effective probiotic strains, this study aims to provide practical recommendations for poultry producers seeking to improve the health and productivity of their flocks in a sustainable and safe manner. Ultimately, this research has the potential to inform evidence-based strategies for enhancing poultry welfare, reducing the need for antibiotics, and meeting the growing demand for healthy and high-quality poultry products in the agricultural industry.
