DOI : 10.9775/kvfd.2019.22272 The purpose of this study is to investigate the effect of oregano oil (Origanum vulgare) at on fattening performance and blood oxidantantioxidant balance such as glutathione (GSH), superoxide dismutase (SOD) and glutathione peroxidase (GPx) catalase (CAT) enzyme activities, malondialdehyde, ceruloplasmin, nitric oxide, albumin, total protein and globulin in post-weaned Tuj breed lambs. The lambs were average 155 days old, and were divided into 3 groups regardless of gender, and in total 18 lambs were used. In the study the control group (C) was fed with basal ration; while the experimental groups were orally fed with oregano oil supplementation as a commercial product in daily doses of 1 mL/lamb/day (T1) and 2 mL/lamb/day (T2), respectively, in addition to the basal ration, via sterile injections. The experiment was maintained for a total of 52 days of which 10 days were adaptation period. In the study, it has been seen in post-weaned Tuj breed lambs that using different doses of oregano oil had no effect on live weight gain, daily live weight gain, daily feed consumption, and feed conversion ratio (P>0.05). In the study, it was determined that the addition of oregano oil to the ration made no significant difference on fattening performance and MDA, GSH, CAT, ceruloplasmin, nitric oxide, albumin, total protein and globulin values of blood oxidant-antioxidant parameters. SOD and GPx values were significantly affected by the addition of oregano oil to the lamb rations at the point of examining the effect on blood oxidant-antioxidant balance (P<0.05). As a result, it has been determined that oregano oil did not affect the performance parameters, it significantly affected the oxidant-antioxidant balance in lambs.
