Long-term influence of turmeric on antibody production induced by Newcastle and Gumboro disease vaccines in poultry observations from day 28 to day 40

ABSTRACT This study examines how dietary turmeric (Curcuma longa) affects immune response in Ross 308 broiler chickens vaccinated against Newcastle Disease (ND) and Infectious Bursal Disease (IBD). Five hundred male chicks were divided into five groups, receiving different turmeric levels (0, 1, 2.5, 5, and 10g/kg feed). Chicks were housed under controlled conditions with free access to feed and water. Vaccinations were administered on days 7, 14, and 21, and antibody titers were measured on days 28 and 40 using the ELISA test. Results showed that chickens fed higher turmeric levels (5 and 10g/kg) had significantly increased antibody titers compared to the control group, suggesting an enhanced immune response. The group receiving 10g/kg turmeric exhibited the highest antibody levels at both time points, highlighting turmeric’s potential as a natural immune booster to improve vaccine effectiveness in poultry. This study suggests dietary turmeric as a sustainable strategy for supporting immune health in poultry, potentially reducing the need for antibiotics and promoting better overall health and disease resistance.
