Abstract: The purpose of the research is to evaluate how dietary supplements of zinc as a micro mineral, and turmeric powder as a herbal growth promoter, affected the Kadakhnath bird's ability to grow as well as its carcass features, meat quality, amino and fatty acid composition. Day one Kadakhnath Chicks were randomly allotted into five experimental groups: T0, T1, T2, T3 and T4 dietary groups. T0 is control group with basal diet whereas T1, T2,T3,T4 were given basal diets enriched with 1% turmeric powder, 1.5% turmeric powder, 1% turmeric powder with 0.5% zinc supplement and 1.5% turmeric powder with 0.5% zinc supplement respectively. Experimental trail was lasted for 75 days. The dietary treatments had no significant effect on the body weight gain and feed intake of the Kadakhnath bird at trail period. Feed conversion ratio of treatment group improved significantly (p<0.05) in comparison with control group .Turmeric powder with or without zinc supplement increase significantly (p<0.05) dressing weight of kadakhnath bird compared to control group. Turmeric powder with or without zinc supplementation does not affect the drip loss % of kadakhnath meat, but it significantly (p<0.05) reduces the pH, cooking loss percentage, and TBARS value of the meat. Through experimentation, it has been found that consuming zinc supplements along with turmeric powder significantly improves the oxidative stability of Kadakhnath meat. The amino acid and fatty acid composition of kadakhnath meat is unaffected by the dietary addition of turmeric powder with or without a zinc supplement. The cost-benefit analysis of the kadakhnath bird revealed that farmers may have benefit from including turmeric in poultry diets. In conclusion, adding of 1.5% turmeric powder in diet will improve FCR, meat quality and combined diet of turmeric and zinc will improve meat oxidative stability.
