Effects of Origanum Syriacum Essential Oil on Blood Parameters of Broilers Reared at High Ambient Heat
Tekce, EGül, M
The biochemical and hematological blood values of broilers fed under heat stress and that were administered Origanum syriacum (OS) essential oil were investigated in this study. In total, 400 male broilers (Ross-308; age, 1 day) were used for the period of 42-days of the study. The experiment included ten groups (n = 50/group; each group divided into five sub-groups): normal heat, 22°C: basal feed (BF)-positive control group (PC), BF + 100 ppm OS; BF + 300 ppm OS; BF + 600 ppm OS). Heat stress, 36°C: BF-positive control group (PC), BF + 100 ppm SOS; BF + 300 ppm OS; and BF + 600 ppm OS). Biochemical and hematological parameters were measured in blood collected into EDTA tubes. Total bilirubin, cholesterol, low-density cholesterol, Na+, Ca2+, and Mg2+ increased, whereas alanine aminotransferase, aspartate aminotransferase, creatine kinase (CK), CK-MB, urea, uric acid, Cl-, and K+ decreased (p 0.05); however, no changes were detected in the other hematological values.(AU)
