Effects of Vitamin E (α-Tocopherol acetate) on Serum Lipid Profile, Ca and P Levels of Broilers Exposed to Heat Stress

The present study presents effect the diet of broilers exposed to heat stress, which the diet was added vitamin E on serum glucose, total protein, triglyseride, total cholesterol, high density lipoproteins (HDL), low density lipoproteins (LDL), very low density lipoproteins (VLDL), hydrocarbon (HC), triacylglycerol (TAG), diacylglycerol (DAG), non-ester fatty acid (NEFA), polar lipids (PL) with calcium (Ca) and phosphorus (P) minerals. Three groups were established, including Control group applied basal ration at +24 °C environmental temperature, Stress group applied basal ration, + 34 °C environmental temperature, and Stress+Vitamin E group applied basal ration by adding vitamin E (150 mg α-tocopherol acetate/kg) at + 34 °C environmental temperature. Blood samples were taken from the animals forty second day and analysed. It was observed that heat stress statistically resulted in an increase in NEFA to ratio, cholesterol, LDL and total protein. Glucose, Ca and P levels also statistically decreased with increase in heat stress, while they increased with applied vitamin E. However, vitamin E did not affect on the value of P. Consequently, the vitamin E added to the ration statistically regulated negative effects of stress on the metabolic profile.
