Thesis Abstract

Abstract
This thesis investigates the effects of dietary supplementation with probiotics on gut health and performance of broiler chickens. The study aims to address the growing concern of antibiotic resistance in poultry production by exploring alternative methods to enhance gut health and overall performance in broiler chickens. Probiotics, known for their beneficial effects on gut microbiota, are being considered as a potential solution to improve poultry health and productivity. The research begins with a comprehensive review of the existing literature on the use of probiotics in poultry production. Various studies have highlighted the positive impacts of probiotics on gut health, nutrient absorption, immune response, and growth performance in broiler chickens. These findings provide the theoretical foundation for the current study. Methodology The research methodology involves a series of experiments conducted on a sample of broiler chickens. The birds are divided into different groups, with some receiving probiotic supplementation in their feed and others serving as control groups. Parameters such as gut microbiota composition, nutrient utilization, immune response, growth rates, and overall health status are monitored throughout the study period. Findings The results of the study indicate that dietary supplementation with probiotics has a significant impact on the gut health and performance of broiler chickens. Birds receiving probiotics show improvements in gut microbiota diversity, nutrient absorption, immune response, and growth rates compared to the control groups. These findings highlight the potential of probiotics as a natural and effective way to enhance poultry health and productivity. Conclusion In conclusion, this thesis provides valuable insights into the effects of dietary supplementation with probiotics on gut health and performance of broiler chickens. The findings support the use of probiotics as a sustainable and safe alternative to antibiotics in poultry production. Further research is recommended to explore the optimal dosage, timing, and specific strains of probiotics for maximizing the benefits in broiler chicken farming. Overall, this study contributes to the ongoing efforts to promote healthier and more sustainable practices in poultry production.

Thesis Overview

The project titled "Effects of Dietary Supplementation with Probiotics on Gut Health and Performance of Broiler Chickens" aims to investigate the impact of incorporating probiotics into the diet of broiler chickens on their gut health and overall performance. This research is significant as the poultry industry continuously seeks ways to improve animal welfare, productivity, and health while reducing the reliance on antibiotics. Probiotics are live microorganisms that, when administered in adequate amounts, confer health benefits to the host. In the context of broiler chickens, probiotics have shown promising results in promoting gut health by modulating the composition of the gut microbiota, enhancing nutrient absorption, and improving the immune response. Additionally, probiotics have been linked to improved growth performance, feed efficiency, and disease resistance in poultry. The study will involve feeding broiler chickens with a diet supplemented with probiotics and comparing their growth performance, gut health parameters, and immune responses with a control group receiving a standard diet. Various methods will be employed to assess gut health, including measuring the diversity and composition of the gut microbiota, evaluating intestinal morphology, and analyzing immune markers. By evaluating the effects of dietary supplementation with probiotics on broiler chickens, this research aims to provide valuable insights into potential strategies for enhancing poultry health and productivity in a sustainable manner. The findings of this study may contribute to the development of alternative strategies to promote gut health and improve the overall performance of broiler chickens, with potential implications for the poultry industry and animal nutrition practices. Overall, this research project seeks to advance our understanding of the role of probiotics in poultry nutrition and their potential benefits for gut health and performance in broiler chickens. Through a comprehensive investigation of the effects of dietary supplementation with probiotics, this study aims to provide evidence-based recommendations for optimizing poultry production practices and promoting animal welfare in the agricultural sector.
