Thesis Abstract

Abstract
This thesis investigates the impact of probiotics on the gut health of broiler chickens, with a focus on enhancing their overall well-being and productivity. The use of probiotics in animal feed has gained significant attention in recent years due to their potential benefits in improving gut health and performance outcomes in poultry production. This study aims to provide a comprehensive analysis of the effects of probiotics on broiler chickens, considering factors such as growth performance, feed efficiency, immune response, and gut microbiota composition. The research methodology involved in this study includes a series of experiments conducted on broiler chickens, where different probiotic supplements were administered through feed or water. The experimental design was carefully planned to assess the impact of probiotics on various aspects of gut health, such as intestinal morphology, microbial diversity, and immune function. Data collection involved measurements of body weight, feed intake, feed conversion ratio, immune parameters, and microbiota analysis. The findings of this study reveal significant improvements in the growth performance of broiler chickens supplemented with probiotics compared to the control group. Probiotic supplementation resulted in higher body weight gain, improved feed efficiency, and enhanced immune response in the treated chickens. Moreover, analysis of gut microbiota showed a positive modulation in the microbial composition, with a higher abundance of beneficial bacteria and reduced pathogenic species. The discussion of the results highlights the mechanisms through which probiotics exert their beneficial effects on broiler gut health, including competitive exclusion of pathogens, enhancement of nutrient absorption, and modulation of immune responses. The implications of these findings for the poultry industry are discussed, emphasizing the potential of probiotics as a sustainable and effective alternative to traditional growth-promoting antibiotics. In conclusion, this thesis provides valuable insights into the impact of probiotics on the gut health of broiler chickens, demonstrating their potential as a natural and safe strategy to improve poultry health and performance. The results of this study contribute to the growing body of knowledge on probiotic supplementation in animal nutrition and underline the importance of promoting gut health for sustainable poultry production.

Thesis Overview

The research project titled "Investigating the impact of probiotics on the gut health of broiler chickens" aims to explore the potential benefits of probiotics in enhancing the gut health of broiler chickens. Broiler chickens are one of the most widely consumed sources of meat globally, and ensuring their health and well-being is essential for sustainable poultry production. The gut health of broiler chickens plays a crucial role in their overall growth, performance, and disease resistance. Probiotics, which are beneficial microorganisms that can positively influence the gut microbiota, have shown promise in improving the health and productivity of various animal species. This research project will delve into the specific effects of probiotics on the gut health of broiler chickens, with a focus on factors such as growth performance, feed efficiency, immune function, and gut microbiota composition. By conducting a series of controlled experiments and data analysis, this study aims to provide valuable insights into the potential mechanisms through which probiotics exert their beneficial effects on broiler chickens. The research will involve administering probiotics to a group of broiler chickens while comparing them to a control group that does not receive probiotics. Various parameters such as body weight gain, feed intake, feed conversion ratio, immune response, and gut microbiota diversity will be monitored and analyzed throughout the study period. Statistical analysis will be employed to examine the differences between the probiotic-treated group and the control group, thereby elucidating the impact of probiotics on the gut health of broiler chickens. Furthermore, this research project will contribute to the existing body of knowledge on poultry nutrition and health management by providing evidence-based recommendations for the use of probiotics in broiler chicken production. The findings of this study are expected to have practical implications for poultry farmers and industry stakeholders seeking to improve the health and performance of broiler chickens in a sustainable and cost-effective manner. In conclusion, this research project on investigating the impact of probiotics on the gut health of broiler chickens holds significant promise for advancing our understanding of how probiotics can be utilized to enhance the health and productivity of poultry species. By elucidating the underlying mechanisms and benefits of probiotic supplementation in broiler chickens, this study aims to pave the way for the development of more effective and sustainable strategies for poultry production and animal welfare.
