Feeding Parents and in ovo Injection Hatching Eggs with Omega-3 Fatty Acid and Sunflower Oil and its Effect on the Physiological Traits of Japanese Quail

Abstract

It was conducted at the poultry field for the period from 12/20/2021 to 2/14/2022. 540 eggs were distributed to nine experimental and injection treatments (60 eggs per treatment). The experimental treatments for the experiment included the following: T1: negative control (without adding oil). T2: positive control (adding sunflower oil) at a rate of 0.01% to the diet. T3: added 0.01 Omega-3 to the parents diet. T4: The parents were fed omega-3 and the resulting eggs were in ovo injected with omega-3. T5: The parents were fed omega-3 and the resulting eggs were in ovo injected with sunflower oil. T6: The parents were fed with sunflower oil and the resulting eggs were in ovo injected with sunflower oil. T7: The parents were fed with sunflower oil and in ovo injected with Omega-3. T8: The parents were fed free-fed and the resulting eggs in ovo injected with omega-3. T9: The parents were free-fed and the resulting eggs were in ovo injected with sunflower oil. The results of the experiment indicated a significant increase on the number of blood cells (WBC) in the blood of both males and females, with a significant decrease in the concentration of hemoglobin (HGB) compared to the negative and positive control treatments. Feeding Japanese quail parents with in ovo injection of Omega-3 hatching eggs led to a significant increase in the concentration of total protein, albumin and globulin in the blood serum of Japanese quail males. While a significant increase in the concentration of total protein was observed with a significant decrease on the concentration of glucose and cholesterol in the blood serum of Japanese quail females compared to the control treatment.
