Thesis Abstract

Abstract
The use of probiotics in animal nutrition, particularly in poultry production, has gained significant attention in recent years due to the potential benefits on gut health and overall performance. This thesis aims to investigate the effects of probiotics on gut health in poultry, focusing on key parameters such as growth performance, gut microbial composition, immune response, and nutrient utilization. The study begins with a comprehensive review of the literature on probiotics in poultry production, highlighting the mechanisms by which probiotics influence gut health and overall performance. Various probiotic strains, modes of administration, and dosage levels are evaluated to determine their efficacy in improving gut health parameters. Methodologically, a randomized controlled trial is conducted using a sample of broiler chickens divided into treatment and control groups. The probiotic treatment is administered through the feed over a specified duration, and key parameters such as body weight gain, feed conversion ratio, gut microbial composition, and immune response are measured and compared between the two groups. The results of the study reveal significant improvements in growth performance metrics among the probiotic-treated poultry, with higher body weight gain and improved feed conversion efficiency. Analysis of gut microbial composition shows a favorable shift towards beneficial bacteria, indicating a positive impact on gut health. Additionally, the probiotic treatment enhances the immune response of the poultry, leading to better disease resistance and overall health. The discussion of findings delves into the implications of these results for poultry producers, highlighting the potential of probiotics as a cost-effective and sustainable strategy for improving gut health and performance in poultry production. The study contributes to the existing body of knowledge on probiotics in animal nutrition and underscores the importance of considering gut health in poultry management practices. In conclusion, this thesis demonstrates the beneficial effects of probiotics on gut health in poultry, providing valuable insights for poultry producers seeking to optimize performance and welfare in their production systems. Further research is recommended to explore additional probiotic strains, dosage levels, and modes of administration to maximize the benefits on gut health and overall productivity in poultry.
