Abstract:Newcastle disease (ND) is a highly contagious and deadly viral infection affecting poultry worldwide, with devastating impacts on rural backyard poultry farmers, particularly in Low-Income Food-Deficit Countries (LIFDCs). Conventional vaccines are often inaccessible or unaffordable for small-scale farmers, necessitating the exploration of alternative, sustainable solutions.
This study evaluates the effectiveness of an ethnoveterinary management (EVM) practice utilizing locally available herbal ingredients-Cumin (Cuminum cyminum), Pepper (Piper nigrum), Turmeric (Curcuma longa), Small onion (Allium cepa), Garlic (Allium sativum), and Keelanelli (Phyllanthus niruri)-for controlling ND in backyard poultry. Experimental findings demonstrate improved body weight gain at weekly intervals over three months and a Benefit-Cost Ratio (BCR) of 3.08 in treated flocks compared to unvaccinated desi birds. The results suggest that this herbal formulation provides a viable, cost-effective alternative for managing ND in resource-limited settings.
