Effect of supplementation of amla, tulsi and turmeric on bio-chemical parameters and immune responses in broilers

An experiment was conducted with three types of herbal preparations (amla, turmeric and tulsi) either alone or in combination in nine dietary treatments to study the bio-chemical parameters and immune responses in broilers. The treatment groups consisted of control (T₁), 0.25% amla (T₂), 0.5% amla (T₃), 0.25% turmeric (T₄), 0.5% turmeric (T₅), 0.25% tulsi (T₆), 0.5% tulsi (T₇), 0.25% amla+turmeric+tulsi (T₈) and 0.5% amla+turmeric+tulsi (T₉) were included in broiler diet. The different types of herbals either alone or in combination at 0.25 and 0.5% levels in broiler diets did not influence the SGOT, SGPT and serum cholesterol levels. The immune response (HI titre) to ND vaccination slightly increased which were insignificant in broilers fed with different herbals either alone or in combination compared to control. The weight of bursa and spleen increased slightly with supplementation of herbals which were insignificant. The results suggested that herbals like amla, turmeric and tulsi can be supplemented in broiler feeds as they have direct effect on improving immunity against Newcastle Disease.
