The effect of omega-3 on phagocytic activity and IgG level was studied on laboratory rats, Twelve white Ratstheirages  ranged between (2.5-3.5) months, and weight between (160-220) grams were divided into three groups, four rats each. The first group were used as a control while the second was given 0.1ml of omgea-3/day and two doses of 0.1 ml was given to the rats in group three. The result showed that the mean phagocytic activity was 19% after 20 days in therats of group two after twenty days of giving the oil, 12.5% for rats in group three and it was 12% , 14% after 30 days of treatment in the rats of group two and three respectively……. The phagocytic activity increased to 26% after 50 days of treatment in group two. The highest level of IgG appeared after 20 days of treatment with one dose of the oil(2469.8)mg/dl, the level of IgG decreased with the increase in the period of treatment after treatment with two doses. A significant correlation appeared in the phagocytic activity of the three groups,no significant difference for IgG.
