The impact of probiotics on growth performance and gut health of broiler chickens.

Thesis Abstract

Abstract
This thesis investigates the impact of probiotics on the growth performance and gut health of broiler chickens. The use of probiotics in animal feed has gained significant attention in recent years due to their potential benefits in improving animal growth and health. In this study, a comprehensive literature review was conducted to understand the current knowledge on probiotics and their effects on broiler chickens. The research methodology involved a controlled feeding trial where broiler chickens were divided into two groups one receiving a probiotic-supplemented diet and the other receiving a standard diet without probiotics. Various parameters, including growth performance indicators and gut health markers, were measured and analyzed. The introduction provides an overview of the research topic, highlighting the importance of probiotics in animal nutrition and the potential benefits they offer to broiler production. The background of the study explores the existing literature on probiotics and their mechanisms of action in improving animal health. The problem statement identifies the gaps in the current understanding of probiotics in broiler production and the need for further research. The objectives of the study outline the specific goals and aims of the research, while the limitations and scope of the study clarify the boundaries and constraints of the investigation. The literature review chapter presents a detailed analysis of previous studies on probiotics in broiler chickens, covering topics such as the modes of action of probiotics, their effects on growth performance, and their impact on gut health. The chapter synthesizes the findings from these studies to provide a comprehensive understanding of the current state of knowledge in the field. The research methodology chapter describes the experimental design and procedures used in the feeding trial, including details on the probiotic supplement, diet formulations, animal management, and data collection methods. The chapter also outlines the statistical analysis techniques employed to interpret the results accurately. The discussion of findings chapter presents the results of the feeding trial, focusing on the effects of probiotics on growth performance parameters such as body weight gain, feed conversion ratio, and mortality rate. Additionally, the chapter examines the impact of probiotics on gut health indicators, including intestinal morphology, microbial composition, and immune response. In conclusion, this thesis provides valuable insights into the potential benefits of probiotics in enhancing the growth performance and gut health of broiler chickens. The findings contribute to the existing knowledge on probiotics in animal nutrition and offer practical implications for the poultry industry. Recommendations for future research and applications of probiotics in broiler production are also discussed.
