A 320 males Domyati ducklings, 20-day-old were utilized, weighed and partitioned into four empirical groups (five replicates each) to assess the dietary Yucca Schidigera(YS) addition (0.0, 0.15,0.30 and 0.45 g/kg diet) effects on growth characteristics, some blood parameters and economic efficiency during summer season within a complete randomize design. Results cleared the dietary YS addition produced heavier (p < 0.001) body weight (BW) for ducklings at 80 d-old. Moreover, both BW gain and feed efficiency were ameliorated (P< 0.001) by adding all YS levels, however feed consumption was escalated (P< 0.001) by adding 0.15 g/kg diet and diminished (P< 0.001) by 0.30 g YS/kg than the control group during the entire period (20-80 d-old). Adding all YS levels to duckling's diet produced a significant (P≤0.01) hike in blood Hb, RBCs and WBCs count as well as lymphocytes (L) cells (%), furthermore, they minimized the heterophils (H) cells (%) and H/L ratio than the control group. Serum triglycerides was attenuated (P< 0.001) consequent to dietary YS addition than the control, while both total cholesterol and LDL-cholesterol were lowered (P< 0.026) by adding 0.15 g YS/kg only. Antioxidant enzymes activity were (P< 0.001) promoted owing to dietary YS addition compared with the control, while MDA was lowered (P>0.05). Abdominal fat (%) was significantly attenuated by dietary YS, but eviscerated carcass and total edible parts (%) were (P< 0.001) better by all YS levels addition than the control. Net return and economic efficiency were improved (P< 0.001) for ducklings fed 0.45 g YS/kg diet than the control at 80 d-old. So, the results signalized that inclusion YS addition with 0.45 g/kg could be maximize and ameliorate the productive performance and carcass traits as well as economic efficiency of males Domyati ducklings throughout growth phase under Egyptian summer conditions.
