The effect of the electric shock on embryonic development and neurophysiological traits in the chick’s embryo

Abstract

The objective of this study was to investigate the impact of stimulating the embryo during the dormancy in the incubation period. 450 eggs (Ross 308) were allocated in four treatments each three replicates. The treatments were as follow: T1 control (without shock), T2 Shocked (40) Millivolts (mV), T3 Shocked (50) (mV), T4 Shocked (75) (mV). A different voltage device was used to shock the egg, after marking the eggs with a line of iron filings to ensure electrical conductivity, eggs were shocked at different times three times a day. The results show a significant increase (p<0.01) in embryonic development for embryo weight, chick body weight, Hatchability, and embryo Index (EI) for T2, T3, and especially T4. A significant increase (p<0.01) in neurophysiological traits of neurons, brain weight, and Brain Index (BI) for T2, T3, and especially T4. In concluding the use of electric shock in the embryonic period will developing of the embryo and neurophysiological traits.
