Objectives: This experiment was performed to investigate the effects of dietary incorporation of extruded flaxseed on egg characteristics, hatchability, and growth performance of English white quails. Materials & Methods: A total number of 288 English white quails at the age of 13 weeks were randomly allocated to 4 treatments with 4 replicates of 24 birds each for 9 weeks for after 4 weeks adaptation. Experimental diets containing 0, 2, 4 or 6 percent extruded flaxseed were offered ad libitum throughout the trial. Different egg criteria were recorded along with growth performance as weekly. Moreover, hatchability of eggs during incubation was determined. Results & Conclusion: The results revealed that including of extruded flaxseed in laying quail significantly increased (p<0.05) egg, yolk, and shell weight, yolk index, shell thickness, egg specific gravity, egg width, height egg. Overall hatchability was significantly (p<0.05) different among various treatments and diet with 4 % extruded flaxseed had the most hatchability. The results of this experiment clearly demonstrated that extruded flaxseed in quails’ diet improved most criteria of egg quality, hatchability and growth performance. Therefore, extruded flaxseed can be useful in quail ration as an approach to improve the productive and reproductive variables of English white quails.
