Effect of in Ova Injection with Nano Selenium and Vitamin E on Hatch and Some Blood Biochemical Traits of Broiler Chicks Exposed to Fasting Condition

This investigation in the hatchery operated by Al-Anwar Poultry Group in Babylon governorate utilized 750 fertilized eggs from January 15 to February 6, 2019. The eggs were partitioned into 5 groups, as follows: T1, serving as a negative control treatment without injection, and T2, serving as a positive control therapy injected with distilled water. Each group included 150 fertilized eggs. Treatments T5, T4, and T3 involved administering a nutritional solution comprising Nano- selenium coupled with vitamin E at dosages of 15-30-45 ppm, respectively, via injection. Subsequently, the chicks were isolated from the injected egg treatments, and each treatment was further divided into three repetitions. The chicks were then cultivated experimentally for 48 hours without any food and were just provided with water. The subsequent outcomes were achieved: Treatment T3 showed a statistically significant difference (P ≤0.01) in the relative hatchability percentage. The treatment T2 (P ≤0.01) markedly outperformed the other treatments in terms of embryonic mortality percentage. There was also a significant excelled(P ≤0.05) for the treatment T1 in the concentration of blood cholesterol and during times 0-12-24-48 hours after hatching, a significant excelled (P ≤0.05) for the treatments T2, T1 in the concentration of triglycerides during the times 0-48 hours after hatching, and the treatment T2 excelled during the times 12-24 hours, a significant excelled (P ≤0.05) for the treatment T2 in the concentration of glucose Blood when hatching, and T3 and T1 treatments excelled12 hours, Treatment T2 at time 24 hours, and highly significant (P ≤0.01) for T2 and T1 at 48 hours after hatching, significant difference (P ≤0.05) for T5 in the concentration of GpX, was significant. Treatment T1 surpassed the established concentration of Malonaldehyde within the first 48 hours after hatching.
