A Novel Phytogenic Solution for Sustainable Poultry Farming: Exploring the Growth-Promoting and Antimicrobial Potential of Sesamum radiatum

Abstract

Aims: This study evaluates the nutritional composition and antioxidant capacity of Sesamum radiatum extracts, with a focus on their potential application as a functional ingredient in poultry feed to enhance growth performance and promote sustainable farming practices. Study Design: Laboratory-based experimental research supported by a short-term in vivo poultry feeding trial. Place and Duration of Study: Conducted at the Integrated Bio Chemical Laboratory, Agro Bio Tech Research Centre Ltd (ABTEC), Poovanthuruth, Kottayam, Kerala, India, in April 2024. Methodology: Proximate analysis was conducted to determine the macronutrient composition of Sesamum radiatum leaves. Soxhlet extraction using hexane, chloroform, and methanol was performed to isolate bioactive compounds from the plant.Antioxidant activity was assessed using the Ferric Reducing Antioxidant Power (FRAP) assay. The extract showing the most potent antioxidant profile was incorporated into a custom-formulated poultry feed, which was then evaluated in a controlled feeding trial to measure its impact on growth performance. Results: The methanolic extract of Sesamum radiatum exhibited the highest concentrations of flavonoids and phenolic compounds, contributing to its strong antioxidant capacity. Nutritional analysis revealed a favorable profile rich in protein, crude fiber, and essential micronutrients. Incorporation of the extract into poultry feed resulted in a noticeable improvement in weight gain among the treated group compared to the control, indicating better nutrient utilization and overall feed efficiency. Conclusion: The findings support the nutritional and antioxidant benefits of Sesamum radiatum, positioning it as a promising phytogenic feed additive in poultry production. Its application may contribute to the development of natural, cost-effective, and sustainable feed strategies, encouraging further long-term research to validate its broader efficacy in animal health and performance.
