The study determined the effect of the addition of 10,20 and 30 gm/kg of sunflower seeds (kernel) to diets for broiler chickens during 1–35 days of age on the blood serum chemistry. One hundred twenty one-day-old broiler chickens were assigned to eight groups (treatments) with two replicates (15 birds per cage). The experiment lasted 5weeks. Broiler chickens receiving diets supplemented with sunflower seeds (kernel). blood biochemical responses of broiler chicks to dietary supplementation with sunflower seeds (kernel) significantly increased HDL, phospholipids and decreased cholesterol, LDL of blood serum in broiler chicks. Adding sunflower seeds to broiler diet lead to improvement the productive parameter (body weight gain, live body weight ,feed intake and feed conversion ratio).
