This study was performed to evaluate and compare three types of chromium supplements, including: organic, inorganic and nano-chromium on some blood parameters as well as growth performance. 24 Mehraban male lambs (3-4 months old with an average weight of 30.85±1.78 kg) in a completely randomized design, using four treatments (each treatment contains six repetitions) were used for 60 days. Experimental treatments were included: 1) control group (basic diet) 2) control group + 0.8 mg inorganic chromium 3) control group + 0.8 mg organic chromium 4) control group + 0.8 mg was nano chrome supplement. The use of organic chromium (treatment 3) compared to the control group caused a significant increase in the final weight of lambs (p<0.05), and all three treatments containing chromium increased daily weight and decreased feed conversion ratio. Treatment 4, significantly reduced the total antioxidant capacity (TAC) when compared to other treatments (p<0.05). All three chromium-containing treatments significantly reduced the amount of malondialdehyde (MDA) and the serum concentration of cholesterol (p<0.05) but did not affect on the increase in glutathione peroxidase (GSH-px) activity compared to the control group (p>0.05). Treatments 3 and 4 had a significant effect on serum glucose concentration compared to the control group (p<0.05). Organic and nano-organic chromium supplements improved the lambs performance, increased total antioxidant capacity and reduced free radicals.
