Effect of Probiotics on Gut Health of Broiler Chickens

Thesis Abstract

Abstract
The poultry industry is constantly seeking innovative ways to improve animal health and productivity. The use of probiotics as a feed supplement has gained attention due to their potential benefits in maintaining gut health and enhancing performance in broiler chickens. This study aimed to investigate the effect of probiotics on the gut health of broiler chickens through a series of experiments and analyses. The research began with a comprehensive review of the literature on probiotics and their impact on gut health in poultry. The literature review highlighted the importance of a balanced gut microbiota in promoting overall health and performance in broiler chickens. Various studies have reported positive outcomes associated with the use of probiotics, including improved feed conversion efficiency, immune response, and reduced incidence of pathogenic infections. The methodology chapter outlined the experimental design, sample collection, and analytical techniques employed in the study. Broiler chickens were divided into control and treatment groups, with the treatment group receiving a probiotic supplement in their feed. Parameters such as gut microbiota composition, intestinal morphology, immune response, and performance indicators were measured and compared between the two groups. The results chapter presented the findings of the study, indicating that the probiotic-supplemented broiler chickens showed a significant improvement in gut health compared to the control group. Analysis of gut microbiota composition revealed a more diverse and balanced microbial community in the probiotic-treated chickens. Intestinal morphology assessments demonstrated enhanced villus height and crypt depth ratios, indicating improved nutrient absorption capacity. Furthermore, the probiotic-treated chickens exhibited a stronger immune response and better growth performance compared to the control group. In conclusion, the study demonstrated the positive impact of probiotics on the gut health of broiler chickens. The supplementation of probiotics in the feed led to improvements in gut microbiota composition, intestinal morphology, immune response, and overall performance of the birds. These findings underscore the potential of probiotics as a valuable tool in promoting gut health and enhancing productivity in broiler chicken production. Further research is warranted to explore optimal probiotic formulations and dosages for maximizing the benefits in commercial poultry operations.
