The present study was conducted to assess the effect of vitamin C (ascorbic acid), vitamin E, organic chromium and its combination on blood biochemical parameters of Narmadanidhi birds in winter season. A total of 240, day old coloured dual type Narmadanidhi chicks were distributed into 12 dietary treatment groups with 20 chicks in 2 replicates in each treatment. The chicks were housed in individual pens as per treatment groups and reared on litter system. Starter and finisher ration were prepared and fed up to 6 and 7 to 12 weeks of age respectively. Dietary treatment supplements in starter and finisher ration were C0 control, C1 (150 mg AA/kg), C2 (250 mg AA/kg), E1 (125 mg vit E/kg), E2 (200 mg vit E/kg) Cr1 (1.25 mg Cr-propionate/kg), Cr2 (2.0 mg Cr-Propionate/kg). Combined supplements were C2E1, C2E2, C2Cr1, C2Cr2, and C2E1Cr2. The data of blood biochemical parameters estimation were recorded to analyse by One way ANOVA. During winter season, Serum glucose, cholesterol was significantly decreased in C₂, Cr₁, Cr₂, C₂Cr₁, C₂Cr₂ and C₂E₁Cr₂ with better effect in Cr₂, C₂Cr₂, C₂E₁Cr₂. Triglycerides were significantly lower in C₂, Cr₁, Cr₂ and all combined supplement and better effect observed in C₂Cr₂, C₂E₁Cr₂. Effect of treatments on Serum protein, albumen, serum Na, K was not observed. Hb was improved in C₂, Cr₁, Cr₂, C₂Cr₁. C₂Cr₂ and C₂E₁Cr₂. Percent PCV was not affected. It was concluded that, combined supplement C2Cr2, C2E1Cr2 had superior performance in winter season.
