Light plays a crucial function in the bird embryo's growth and development, and its absence may lead to failure-hatching or embryo deformity. Thus, the investigation aimed to determine the significance of light colors on chickens' growth and embryonic development. This investigation was performed at the College of Agricultural Sciences, University of Sulaymaniyah, Iraq, to examine how light colors impact embryonic development, Hatchability, and hatched chick quality. Four treatments were used: Dark without light (control) (D), red light (RL), blue light (BL), and green light (GL), with three replications (25 egg/replicate). In total, 300 eggs (ROSS 308) were fertilized, and 75 eggs were laid in each incubator (each treatment in the incubator separately; the incubators were similar in all circumstances). The outcomes showed a considerable increase (P<0.01) in the embryonic development of the embryo length (mm) at the first stage of incubation, age of three days, as well as a considerable increase in the vascular area (mm) development and the No of somites pairs if all the experimental treatments exceeded the D. The treatment of the whole experiment in the ratio of the weight of the embryo on D as well as a meaningful improvement (P<0.01) in the albumin and yolk weight for the treatments. There was a considerable expansion in the hatchability (P<0.01) and the quality for all the investigation treatments in comparison to the D. In conclusion, using light during the embryonic period will affect embryo development, embryonic traits, hatchability, and chick quality

Abstract
Adding aromatic oils (Miarom) in drinking water of broiler breeder was evaluated experimentally of its effect on hatchability percentage, immunity, Lipid profile, and biochemical traits at different laying times (10:00 AM and 02:00 PM). A total of 3600 eggs of broiler breeder (Ross-308) at age 60 weeks, ...

Adding aromatic oils (Miarom) in drinking water of broiler breeder was evaluated experimentally of its effect on hatchability percentage, immunity, Lipid profile, and biochemical traits at different laying times (10:00 AM and 02:00 PM). A total of 3600 eggs of broiler breeder (Ross-308) at age 60 weeks, were collected and divided into 5 treatments of different times of egg collection and laying times as follows: (T1: General Control, T2: Control 10:00 AM, T3: Control 02:00 PM, T4: Miarom 10:00 AM and T5: Miarom 02:00 PM). Results indicated the used Miarom from Miavit company - Germany (this extract contains: 200 grams essential oils mixture such as eucalyptus oil, anise oil, thyme oil, and peppermint oil) per litter it added in drinking water 1ml/10L for 7 days. The results of this study showed (p≤0.01) increased in hatching traits percentage, chick’s antibody titer against Newcastle Disease (ND) and Infectious Bronchitis Virus (IBV) by ELISA, high-density lipoprotein HDL, total protein and glutathione GSH-Px antioxidant enzyme. Also, significantly (p≤0.01) reduced infertile eggs, triglycerides TG, total cholesterol TCH, low-density lipoprotein LDL, corticosterone hormone, and malondialdehyde antioxidant enzyme. In conclusion, results showed that aromatic oils supplementation in broiler breeders leads to improve hatchability and immune status at different laying times, noticed that both Miarom treatments had a positive effect on studied parameters and T4 10:00 AM laying time was most effective in all parameters of the study.

Abstract
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 ...

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.

The present trial was conducted to investigate the effect of using bay leaf powder and its oil on male semen characteristics, female reproductive traits, plasma hormonal alteration and hatchability of local quails. The results were summarized the uses of different levels of bay leaf (Laurel nobilis L.) and its oil as feed additives in quail diets were significantly (P≤0.05) higher in body weight, testis relative weight, gonadosomatic index, size area of cloaca gland, ejaculate volume, sperm concentration, mass motility, individual motility, live & normal morphology sperm, semen quality factor, seminal plasma testosterone and LH hormones in quail males. Also in females: egg production (H.D %), egg weight, egg mass, eggshell strength, normal eggs for hatching, fertility, hatching of fertile and total eggs, weight of hatched chicks, blood plasma of estrogen, LH and FSH hormones concentrations, also improved in FCR and H/L ratio. While, the results seemed significantly (P≤0.05) lower in dead sperm. Females in: cracked eggs, total dead embryos. Whereas there were non-significant differences among all treatment in males: mortality, left-right testicular weight ratio, testicular shape index, FSH hormone, also females in: feed Intake. From the results of bay leaf oil additives had positively effect on body performance, males and females' reproductive parameters, improved blood hormones and hatchability more effective than bay leaf powder
