SUN-LB084 The Effect Of Stimulating The Neural Response On Some Endocrine Hormones In Chicks

The neural response in the chick is beginning during the development of nerves and the 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 stimuli to chicks inside the egg. The chick will gain comfort and safety for the hen's feeling beside it. From here, the study focused on the stimuli that help to release the hormones of welfare in organismsThis study was carried out in University of Anbar, use the sound as a stimulant to stimulate the hormones of welfare by using 240 fertilized egg (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 (100-200 Hz) sound density of 65 dB. the results showing: significantly (P≤0.01) improvement in neural response (motility of nerves ) and improvement in physiological response ( brain development, weight brain, and increasing growth hormone and prolactin hormone) Unless otherwise noted, all abstracts presented at ENDO are embargoed until the date and time of presentation.
