Abstract :The neural response in the chick is beginning during the development of nerves and formation of the brain. At this stage, the chick begins to discriminate and recognize the external stimuli, as sound, light, and heat...etc. In nature, the hen incubates eggs and released the sound for hearing to chicks inside the egg. The chick will gain comfort and safety for the hen`s feeling beside it. But in the artificial hatchery, there isn`t this technical. So,  the hatcheries were provided with different sounds as external stimuli and studied the neural response and physiological response. This study was carried out in University of Anbar, College of Agriculture, Animal Production Dept. by using 240 fertilized egg insert ignore into journalissuearticles values(Ross 308);, distributed to four treatments,T1= first treatment control treatment without hearing any sound, T2= second treatment hearing the hen call , T3= treatment third hearing  chicks hatched call and T4= treatment fourth hearing chick with hen call, each treatment divided into three replicates and each repeater 20 eggs, hearing the sound from the age of 5 days form incubation and until the day of hatching, the sound was given for a period of 15 minutes per hour in 24 hours, with usually insert ignore into journalissuearticles values(100-200 Hz); sound density of 65 dB. the results showing: significantly insert ignore into journalissuearticles values(P≤0.01); improvement in neural response insert ignore into journalissuearticles values(motility of nerves ); and improvement in physiological response insert ignore into journalissuearticles values(brain development, weight brain, and increasing growth hormone and prolactin hormone);
