This study was conducted at the Badi Hatchery and poultry house / department of animal production / College of Agriculture engineering science/ University of Duhok. The aim of study was to investigate the effect of different administration methods of vitamin AD3E to hatching eggs on hatchability and post hatch productive performance and some physiological parameter of broiler. A total of one thousand and two hundred fifty (1250) hatched eggs were distributed into five groups each groups 250 eggs. The experimental treatments were as the follow: T1 (Control), T2 (sham control)(injected with 0.1 ml normal saline), T3 (injected with 0.1 ml of vitamin AD3E dissolved in 5 ml of vitamin in 1 ml of water) T4 (Spraying vitamin AD3E 1 ml /L water), T5 (Dipping vitamin AD3E 1 ml /L water). During the rearing period, each treatment divided into 2 group of replications, (5 replication) for each group that is from one treatment exactly. First 5 five replications (R1-R5) for each treatment given different doses of vitamin at different rearing age via drinking water and other 5 five replications (R6-R10) were drink normal water throughout the rearing period which is at least 5 weeks. Weekly Live body weight, body weight gain, feed consumption, feed conversion ratio, mortality percentage, Production index were recorded, (Total protein, glucose and cholesterol), blood serum titer for testing the immunity of chicken against diseases Newcastle (ND) and Gumboro, infectious bronchitis (IB). The overall data shows the following results: In hatching stage there were significant affect in chick weight and chick to egg ratio and in rearing stage live body weight, body weight gain, feed conversion ratio, production index, serum glucose, Newcastle Gambaro and infectious bronchitis disease.

Many researchers were administrated that possible increasing hatchability, vitality with enhance growing with early nutrition of chicken embryos through exogenous antioxidant and nutrient solution by in ovo technology (31). A number of nutrients have an important physiological, nutritional and immunological functions related to the bird’s embryogenesis and growth rates. In ovo injection of these nutrients may help overcome any constraints imposed by inadequate egg nutrition (34). Moreover, in ovo injection is one of the unique ways of entering the nutrients of the fetus during the incubation period is through the injection process (27) injections are egg-like nutrients such as Carbohydrates, proteins, amino acids, vitamins and vaccines can promote embryo growth, improve energy production and promote early intestinal development by increasing the development of intestinal function and improving the of immunity (19).Vitamin E is a biological antioxidant that could contribute to improved growth, physiological, and immunological performance in broiler chickens because of its ability to neutralize free radicals and reduce lipid peroxidation in both the plasma and skeletal muscle (20;35). Oxidative stress has been regarded as one of the major factors negatively affecting the performance of birds in the poultry industry (40). Vitamin A considers one of the necessary vitamins during normal embryo development stages and plays an important role in maintaining the differentiation and cellular specialization in the organism. (32).Vitamin D3 is one of the fat soluble vitamin, which is important for the mussel growth the embryo, where the target organs include the intestine, kidney, bone, ovary, testis and pituitary gland (15). Vitamin D3 increases the proliferation and differentiation of muscle cells through its role in DNA synthesis and support the growth of the muscles of the emptying fetus and an increase in its length and maturity (10). Spraying of hatching eggs is one of the methods for administration of nutrients for the eggs, (28) found that spraying Japanese quails eggs with different level of glucose had effect on the hatching traits. The hatchability percentages of Muscovy duck eggs were improved by dipping eggs into ascorbic acid solution when compared to the control on the 0, 14 th and 30 th days of incubation (21). MATERIALS AND METHODS The experiment was conducted at the ( Badi) hatchery that located near to the Badi village at Duhok governorate, all the rearing and sampling work of this study were at the poultry farm of Animal Production Department, College of Agriculture, University of Duhok, Kurdistan region, Iraq. A total of one thousand two hundred and fifty 1250 forming the broiler breeders flock their origin was from Portugal (Rose 308: broiler breeders age, 32 weeks, first cycle of percentage, average eggs weight 57 to 58 g . The trial was started on January 7, 2019 for the period 10 weeks. This investigation was approved by the animal production department scientific committee of college of agriculture, University of Duhok. Eggs incubation and flock rearing A total of one thousand two hundred and fifty 1250 eggs distributed into 5 groupsof 250 eggs and set in a force draft incubator at temperature were Eggs incubated at 37.5°Cand 54–55 % relative humidity environment, ventilated by a big fan and water tube cooling system. First group (T1) acted as a control (uninjected) and second group(T2) injected with distilled water or normal saline (0.1ml /egg), forth group (T3) was injected by the vitamin AD3E (0.1 ml / eggs ) and after dissolved 5 ml vitamin to 1 litter of sterile water on 18 th day of incubation by using a 27 gauge 0.40mm × 25 mm needle this needle was teeth disposable endodontic and periodontal irrigation tips from the company (Dia Dent) and with Socorex ® syringe that is very good for injection due to not make embryo be injured and coming blood if touch body of Iraqi Journal of Agricultural Sciences –2021:52(2):322-335 Hassan & Tayeb 324 chicks inside eggs . At7 th day of incubation (T4) was acted as a spraying with AD3E solution (1ml/ 1liter)and fifth group (T5) was acted as a dipping with AD3E solution (1m/1litter).All unhatched eggs were broken to insure proper hatching result; after that the hatched chicks were transported separately to the farm, using special individuals transport cages for each treatment group. On the day of hatch the chicken were weighting and hatching percentage and mortality was recorded. Serum biochemical and immunity Blood samples were collected (5 ml) at the day 35 of the study by venipuncture of the neck vein, then, the blood samples will keep on ice and transfer to the laboratory blood tubes were kept in the refrigerator for 48 hours and then placed in centrifuge to 1500 revolution for 10 min to separate the serum . The serums was separate and stored at -20 °C till the measurements of the (Glucose and Cholesterol and Total protein) by auto analyzer (COBAS INTEGRA 400 plus). And immune parameters Antibiotics titration against Newcastle disease (ND), IBD and infectious bronchitis (IB) diseases were performed using ELISA by specific kits of OVATEC ® Plus, SERELISA ® Rabies (Synbiotic,USA),and BIA-CK ® 121 Biochek , Netherland.
