Type: article
Abstract: This study evaluated the anthelmintic efficacy of Lagundi (Vitex negundo) leaf powder against gastrointestinal parasites in naturally infected free-range chickens and its potential as a plant-based alternative to synthetic dewormers. Grounded in the growing need for sustainable and accessible parasite control strategies, the study employed a Completely Randomized Design involving seventy-five (75) helminth-infected chickens assigned to three Lagundi treatment levels (120 mg, 240 mg, and 360 mg), a positive control (Albendazole + Praziquantel), and a negative control (distilled water). Fecal samples were collected at Days 0, 7, 14, and 21 and analyzed using the McMaster technique to determine eggs per gram (EPG) and fecal egg count reduction (FECR), while necropsy was conducted to confirm adult parasite presence. Results revealed a significant dose- and time-dependent reduction in parasite burden, with the highest Lagundi dose (360 mg) achieving up to 91.67% FECR and complete elimination of adult gastrointestinal parasites, while lower doses showed moderate efficacy. Statistical analysis using ANOVA indicated significant differences among treatments (p < 0.05). Although the positive control achieved 100% efficacy, Lagundi demonstrated strong anthelmintic potential supported by observed reductions in nematodes such as Ascaridia galli, Heterakis gallinarum, and Capillaria spp. The study concludes that Lagundi leaf powder is an effective natural alternative for controlling gastrointestinal parasites, though further research is recommended to optimize dosage, isolate bioactive compounds, and validate findings under field conditions. The study supports Sustainable Development Goals (SDG) 2 (Zero Hunger), SDG 3 (Good Health and Well-being), and SDG 12 (Responsible Consumption and Production) by promoting sustainable poultry health management through plant-based alternatives. Its sustainability impact lies in enhancing food security, reducing reliance on synthetic drugs, and supporting environmentally friendly and cost-effective livestock practices for smallholder farmers.
