Project Abstract

This project aims to investigate the impact of probiotics on the gut health and productivity of broiler chickens, a crucial aspect of the poultry industry. Broiler chickens are a significant source of protein worldwide, and their growth and health directly affect the industry's productivity and sustainability. However, the use of antibiotics in poultry farming has raised concerns regarding antibiotic resistance and the need for alternative, more natural approaches to maintaining bird health. Probiotics, defined as live microorganisms that, when administered in adequate amounts, confer a health benefit on the host, have emerged as a promising solution to address these challenges. Numerous studies have suggested that the inclusion of probiotics in broiler diets can improve gut health, enhance nutrient absorption, and promote overall bird performance. By modulating the gut microbiome, probiotics can strengthen the immune system, reduce the incidence of gastrointestinal disorders, and potentially mitigate the need for antibiotic interventions. This project aims to evaluate the effectiveness of probiotic supplementation in improving the gut health and productivity of broiler chickens. The study will involve a controlled experiment, where a group of broiler chickens will be fed a probiotic-supplemented diet, while a control group will receive a standard diet. Throughout the trial, various parameters will be monitored to assess the impact of probiotics, including 1. Gut microbiome composition The project will employ advanced DNA sequencing techniques to analyze the diversity and abundance of gut microbial communities in both the probiotic-fed and control groups. This will provide insights into how probiotics influence the overall gut microbiome. 2. Intestinal morphology and function The project will examine the intestinal structure, including the length, villus height, and crypt depth, as well as the expression of key digestive enzymes and nutrient transporters. These measures will indicate how probiotics affect the gut's capacity for nutrient absorption and overall intestinal health. 3. Growth performance and feed efficiency The project will track the body weight, feed intake, and feed conversion ratio of the broiler chickens in both groups to evaluate the impact of probiotics on growth and productivity. 4. Immune status and disease resistance The study will assess the birds' immune function, including the levels of circulating antibodies and the activity of immune cells, to determine the potential of probiotics in enhancing the birds' resistance to diseases. By addressing these key parameters, the project aims to provide a comprehensive understanding of the benefits of probiotic supplementation in broiler chicken production. The findings from this study could have significant implications for the poultry industry, as they may offer a viable alternative to antibiotic use, leading to improved gut health, better growth performance, and reduced reliance on antimicrobial interventions. Furthermore, the insights gained could be valuable in developing more effective probiotic-based strategies for sustainable and environmentally friendly poultry farming practices.
