摘要

A total of 12, 36-week-old of Muscovy drakes were divided randomly into three equal groups (4 individuals each) and subjected to supplementation of VE-Se in combine form in drinking water. The first group was served as control group (C), while the second and third groups (T1 and T2) were supplemented with 1.0g/l and 1.5g/l of VE-Se in drinking water, respectively. The study was performed at poultry research station which belongs to department of poultry production, faculty of agricultural, Ain Shams University and lasted 30-dayes period during summer season. Semen quality traits in terms of ejaculate volume (ml), spermatozoa concentration (×109), sperm motility (), dead and live (), PH value and abnormal sperms () were determined. Sperm reserves in ducts, seminiferous tubules diameter (STD) and relative spermatogenic activity were also studied. The obtained results indicated that addition of vitamin E-Se improved ejaculate volume, sperm concentration and motility score, while reduced the percentage of abnormalities and dead sperms. Results showed that semen ejaculate volume was significantly increased (P0.05) with increasing the level of VE-Se supplementation in drinking water. Spermatozoa concentration, progressive motility (), and packed sperm volume were increased significantly with VE-Se treatment. The percentages of dead and abnormal spermatozoa were significantly decreased (P0.01) in VE-Se treated compared with the control drakes. Concerning with the effect of two levels (T1 and T2) of VE-Se supplementation in drinking water of Muscovy drakes on the morphometric traits of testis, the obtained results showed that highly significant effects of antioxidant (VE-Se) supplementation on the morphometric of seminiferous tubules (p 0.05) and the higher values of sperm reserves and spermatogenic activity percentage in both T1 (4.4/ml×109 and 82.8) and T2 (4.5/ml×109 and 83.0) compared with control group (3.2/ml×109 and 61.3). We conclude that VE-Se supplementation could lead to greater economic benefits through increased reproductive efficiency within the ducks production industry.
