Abstract
The aim of this study was to identify the effect of exposing broiler breeders eggs to magnetic field before hatching on hatchability and productive performance of progeny. In this research, 300 fertile eggs produced by breeders of Ross 308 were used. they were divided into four Treatments (Seventy-five eggs for each) The Eggs were treated as follows: T1 Control not exposed to magnetic field, T2 eggs exposed to magnetic field 1800 Gauss for 30 minutes, T3 eggs exposed to magnetic field 1800 Gauss for 60 minutes, T4 eggs exposed to magnetic field 1800 Gauss for 90 minutes. After hatching chicks reared under normal condition in semi opened house until 42 days of age. Statistical data analysis revealed that exposure of the eggs to the magnetic field for 30 minutes induces a substantial increase (p ≤ 0.05) in the percentage of hatchability, live body weight, total weight gain, dressing percentage, output index, W.B.C., R.B.C., P.C.V., hemoglobin and blood glucose, also, a decline in mortality of fetuses and variation in feed conversion between treatments.
