dc.description.abstractTwo biological trials were conducted to study the effect of supplementation of Chromium yeast and Nano chromium on the growth performance and meat quality in Trial I in dual purpose chicken and egg production and egg quality in dual purpose birds during peak production in Trail II. Both the trials had eight treatment with 800 birds (100 per treatment) in the I trial and 576 birds (72 per treatment) in the II trial. Control diet (T1) was formulated according to NRC (1994) specifications. To the basal diet, Chromium yeast was added to contain 200, 400 and 600 ppb levels of Cr to form T2, T3 and T4, respectively and Nano Chromium was added to contain 50, 100, 200 and 400 ppb levels of Cr to form T5, T6, T7 and 8, respectively. In the Trial I, the cumulative body weight, feed intake and FCR at the end of eight weeks were not affected by Cr supplementation. Both Cr yeast and Nano Cr significantly (P≤0.05) increased serum levels of total protein, albumin, globulin, antibody titre against NDV and IBDV, Hb per cent, Cr content in blood and tissues, produced lean meat and reduced serum TG, cholesterol, glucose, hetroplil to lymphocyte ratio and abdominal fat content. The retention percentage of Cr was significantly higher in Nano Cr groups than Cr yeast groups. In the trial II, Cr supplementation from either sources increased egg production, egg weight, albumen index, Haugh unit score, Crcontent in eggs and reduced yolk index, fat and Cholesterol content in eggs. The feed cost economics revealed significant reduction in feed cost per egg, per unit of Cr deposition in meat, liver and eggs with supplementation of Cr yeast and Nano Cr. The meat and eggs enriched with Cr could be used as functional food by patients with Type II diabetes mellitus.en_US
