摘要：

1. This study evaluated the duodenal wall integrity, antioxidant status as well as some immunological parameters of broiler chickens supplemented with 0.5g Thymus vulgaris essential oil (EO)/kg diet and 0.4mg Se/kg DM (dry matter) derived from sodium selenite.2. A total of 192 one-d-old randomly divided chickens of both sexes (Ross 308 hybrid broilers) were divided into 4 treatment groups of 48 birds each.3. The first group was fed on a nutritionally balanced basal diet (BD). The other three groups received BD supplemented with 0.5g/kg thyme oil, or 0.4mg Se/kg DM, or both feed additives together.4. The results for the evaluated feed additives were (1) thyme oil - decreased malondialdehyde (MDA) concentration in duodenal mucosa and kidney, increased immunoglobulin A (IgA) concentration in duodenal mucosa, stimulated phagocytic activity in blood, improved intestinal barrier integrity (2) selenium - increased glutathione peroxidase (GPx) activity in blood and liver as well as thioredoxin reductase (TrxR) activity in duodenal mucosa, liver and in the kidney, (3) EO with selenium - increased thioredoxin reductase (TrxR) activity in duodenal mucosa.5. These results demonstrated that thyme oil alone showed more effective potential to improve intestinal barrier integrity and antioxidant status as well as evoking an immune response in chickens, than if diets were supplemented with both thyme oil and selenium.
