BACKGROUND Trivalent chromium (Cr) is involved in carbohydrate, lipid, protein and nucleic acid metabolism in animals. This study evaluated the effects of different organic Cr forms with Cr methionine (CrMet), Cr picolinate (CrPic), Cr nicotinate (CrNic), and Cr yeast (Cr‐yeast) at the level of 400 μg kg−1 Cr, on growth performance, lipid metabolism, antioxidant status, breast amino acid and fatty acid profiles of broilers. In total, 540 one‐day‐old Arbor Acres male broilers were randomly assigned to five treatments with six replicates (18 broilers per replicate) until day 42. RESULTS The results showed growth performance was not affected by Cr sources. The Cr‐yeast group had lower serum cortisol levels than the CrNic group (P
