The results cleared that, at 18 th day the egg weight ranged from 60.50 in the group treated with 5 % M. Water extract to 62.16 gm in control group. While, the egg losses observed in group 4 that, treated with 2 % M. water extract that was 20.56 % at 21 st day. The higher hatchability % of total eggs showed in control group that was 69.70 %. While, the hatchability % of fertile eggs showed a higher percentage in group 5 that treated with 5 % M. Water extract that was 99.02 %. The higher percentage of dead embryo observed in control group that was 9.10 % and the lower level observed in the group 2 that treated with 2 % M. Alchole exteract that was 5.46 %. The total aerobic bacteria counts at 18 th day of incubation showed a lower level in group 5 that treated with 5 % M. water extract that was 7.88. while, the activity of chicks and in abnormal chicks in- creased in group that treated with 5% M. Water extract that was 8.96 % and 2 % respectively. Overall, the higher concentration of Alchole extract of M. olifera , increased the weight of hatching eggs with a reduction in total egg losses,% of the eggs. While, the higher con- centration of the water extract of M. olifera improved the hatchabil- ity % a reduction in total aerobic counts on the egg shell and im- proved chick quality and activity. Keywords: Moringa oleifera, extraction, hatching eggs Introduction Eggs and hen meat account for 35.56% of the global human animal protein require- ment [1]. Given the advances in consumption of animal merchandise in developing countries, consumption of chicken products is anticipated to increase by 3.9%, with beef and pork taking 2nd and 2nd place, respectively.9% and 2.4% by using 2020 [2]. To meet this demand, a large manufacturing of day-old chicks is required. The goal of the hatchery is to attain a high brood yield of very desirable quality day-old chicks in order to maximize profitability [3]. broilers are an necessary source of protein and proper source of earnings in countries with food shortages because, in addition to the
