Özet
Sesame seed (SS) and sesame oil (SO) are rich sources of unsaturated fatty acids, lignans, and natural antioxidants that have been reported to improve poultry performance and health. However, their relative biological efficacy under identical experimental conditions has not been directly compared. This study evaluated the comparative effects of dietary sesame seed (20 g/kg) and sesame oil (1.5 mL/kg) supplementation on production performance, egg quality, serum biochemical profile, antioxidant status, intestinal microflora, and intestinal morphology in Rhode Island Red laying hens. A total of 180 laying hens were randomly assigned to three dietary treatments: a control diet, control supplemented with sesame seed (20 g/kg), and control supplemented with sesame oil (1.5 mL/kg). Neither sesame seed nor sesame oil affected feed intake or egg quality (P > 0.05). Both dietary supplements significantly increased egg production, hen-day production, and feed conversion efficiency while improving serum lipid profile by reducing low-density lipoprotein and total cholesterol and increasing high-density lipoprotein (P < 0.05). Antioxidant capacity was enhanced through increased superoxide dismutase, glutathione peroxidase, and total antioxidant status, whereas malondialdehyde remained unchanged (P > 0.05). Both treatments reduced fecal Escherichia coli and Salmonella populations and improved intestinal morphology by increasing villus height and villus height-to-crypt depth ratio while reducing crypt depth (P < 0.05). Across most measured parameters, sesame oil produced significantly greater improvements than sesame seed. Both sesame seed and sesame oil improved productive performance, metabolic health, antioxidant status, gut health, and intestinal morphology without compromising egg quality. Sesame oil consistently exhibited superior biological efficacy, indicating that it is a more effective sesame-derived functional feed additive for enhancing the productivity and physiological health of laying hens.
