Organic Acids (BacterActive) spraying and dipping on hatching eggs were evaluated experimentally for their effect on embryonic mortality, hatchability, chick quality, immunity, and eggshell bacterial count. A total of 6300 hatching eggs of broiler breeder (Ross-308) at age 58 weeks, were collected and divided to 7 treatments as follows: (T1: General Control, T2: Dipping Water, T3: Spray Water, T4: Dipping and spraying water, T5: Dipping organic acid, T6:spray Organic Acid, T7:dipping-spray organic acid ) Results indicated that using Organic acid (BacterActive) a synergetic blend of formic – propionic - lactic acids applied in a spraying manner with a concentration of 1ml/l significantly (p≤0.01) increased hatching traits, chick quality, and chicks’ antibody titer against Newcastle Disease (ND) and Infectious Bronchitis (IB) also organic acid application significantly reduced embryonic mortality and eggshell total bacterial count in all treatments. while T6 showed the best result among all treatments that used organic acid and T5 showed the lowest value. among control group T3 had the best overall result while T1 shows least favorable result of all treatments. A special note to take in consideration is that dipping eggs in water T2 had least impact on embryonic death. In conclusion results showed that organic acids application via spraying, dipping, and dipping-spraying in broiler breeders leads to significant improvement of hatchability, chick quality and immune status while decreasing embryonic mortality and eggshell total bacterial count.
