The study was conducted in college of agriculture and forestr y fields department of animal production during the period 1/9/2021 to 1/12/2021, ejaculated were collected on 6 awassi rams with weight 45.63±1.32 kg and aged 1.5-2 year, dilution ratio was 1/16.

semen was collected from rams once a tow week through the period of theexperimental using electro-ejaculator for semen .the experiment was conducted to study the effect of magnetization of diluted semen (non-magnetic, magnetic of one hour, magnetic two hours and continuous of magnetic strongly 1800 gauss) and preservation periods (24, 48, 72 and 96 hours) on semen characteristics (mass motility, individual motility, ph of semen, percentages of dead, live and abnormal sperm).

the results indicated that the process of magnetizing the diluted semen led to a significant effect (a ≤ 0.05) in increased the percentage of individual motility sperm, live sperm and reducing the percentage of dead sperm.

the period of cryopreservation (5 ° c) had a significant effect (a ≤ 0.05) in decreasing the characteristics of the studied diluted semen and in increasing the percentage of dead and deformed sperm.

we conclude from the above that the magnetization of semen for an hour or two with a intensity of 1800 gaus has a positive effect on the characteristics of the diluted semen, and that the advance of the storage period (5°c) has a negative effect on the characteristics of the diluted semen.
