Abstract: | This work investigated the outcomes of dietary administration of Echinacea purpurea (EP) powder to breeder ducks on productive and reproductive performance during summer season. Sudani ducks (320 birds) of 32-weeks-old (240 females and 80 males) were randomly allocated into four collections (body weight; 1850 ± 15.2 g for females and 2960.0 ± 40.5 g for males). The primary collection consumed the basal diet without supplementation and was deliberated as control. The other three collections were fed the basal diet supplemented with 2.5, 5.00 and 7.5 g EP/kg diet, correspondingly. Egg number and mass, laying rate, feed consumption and feed conversion ratio (FCR) were significantly changed by dietary EP levels. Drakes fed EP-supplemented diets had higher ejaculate volume, sperms concentration and live sperms (%) as well as lower dead sperms (%) than the control group. Eggs laid by ducks fed diet supplemented with 2.5 g/kg had the greatest fertility and hatchability percentages, followed by those fed 5.0 g EP/kg. Ducks fed different EP diets had higher values of haemoglobin, RBCs, WBCs and lymphocytes, lower values of heterophils percentage and lower H/L ratio than the control. All serum constituents were significantly changed by dietary EP supplementation, except of total protein and Alanine Aminotransferase (ALT) enzyme. Conclusively, dietary EP supplementation at 2.5 g/kg had beneficial effects on productive and reproductive performance as well as lipid profile and antioxidant status and economically valued in breeder ducks under summer conditions. |
