Abstract: Three hundred day old broiler straight run chicks of “Vencobb 400” strain were equally and randomly distributed into five treatment groups which subdivided three four replicates containing 20 chicks in each. The dietary treatment groups were the control diet (BIS, 2007, A), Basal diet + Vitamin C @ 250 mg/ kg diet (B), Basal diet + Chromium picolinate @ 2.5 mg/kg diet (C), Basal diet + Magnesium sulphate @ 2.5 g/kg diet (D) Basal diet + Vitamin C @ 250 mg/ kg diet + Chromium picolinate @ 2.5 mg/kg diet + Magnesium sulphate @ 2.5 g/kg diet (E). The total protein, albumin and ALP were observed significantly higher all heat stress alleviating agents (CrPic, VitC and MgSO₄) groups at 21 and 42 day of age as compared to control. However, the serum glucose and cholesterol were observed significantly lower in bird fed alone or in combination heat stress alleviating agent groups at 21 and 42 day of age as compared to control. In conclusion, Chromium picolinate, Vit.C and MgSO₄ alone or in combination can be use in diet of broiler birds during summer.
