Productive and Physiological Performance of Laying Hens Under Different Levels of Okra Powder

Abstract

Abstract The aim of this study was to investigate the effects of adding okra powder, C and E vitamins to diets on the productivity, physiological, and some antioxidants indicators of laying hens. A total 300 laying hens used in this experimental distributed into five treatments, three replicate each (n=15 hens each replicate) and reared under conventional conditions. T1: control (commercially based laying hens diet); T2: (Control+250 mgVit. C/kg feed); T3 (control diet+200 mg Vite. E/kg feed); T4: (control+2 g Okra/kg feed); and T5: (control+4 g Okra/kg). The result show : There were significant differences in laying performance (HD%) in T2 compared to the other treatments in the period (38-41). Egg weight and egg mass were affected by feeding of okra powder, vitamin C and E compared to the control treatment. Serum triglycerides concentration was significantly lower in T4 compared to the other treatments. On the other hand, the MDA concentration significantly decreased and increased GSH concentration in T2, T3 and T4 compared to the T1 and T5. Estrogen hormone concentration was significantly higher in T3, T4, and T5 compared to the other treatments
