An experiment was conducted in the fields of the poultry unit - Livestock Division - Nineveh Research Department, to find out the effect of using low-intensity magnetic flux (110 Gaos) in two periods of incubate quail eggs, on the growth and production performance of the resulting birds, the results showed a significant increase (P ≤0.05) for the magnetic flux treatment on control treatment for hatchability% and fertility%, the percentage of dead embryos decreased significantly (P ≤0.05) for the second exposure period treatment than the control treatment, the two magnetic exposure treatments were significantly superior (P ≤ 0.05) to control treatments in the body weight at one and four weeks age (g), weight gain (g) and food conversion ratio (g/g). The magnetic exposure treatment also achieved a significant decrease (P ≤0.05) for the number of days to reach sexual maturity (or the days to obtain 5% egg production) and for food consumed / kg. The two magnetic treatments were also significantly superior in food conversion ratio (kg feed / kg egg) for the eight-week period of egg production.
