This experiment was carried out at the faculty of agriculture and veterinary medicine, department of animal production in Thamar University, Yemen. As known, the use of antibiotics as growth promoters is banned in many countries due to the residual side effects and growing resistance to antibiotics of disease caused by bacteria by animals and human. So, feed additives of plant origin such as essential oils or extracts of aromatic plants have received considerable attention as alternatives to the traditional antibacterial feed additives. Thereby it was conducted to examine the effects of black cumin seeds (Nigella sativa) on growth performance (average body weight, weight gain, feed intake, feed conversion), carcass traits and some blood parameters (glucose, cholesterol, total protein, albumen) in broiler chickens. A total of 144 seven-days-old Hubbard strains were divided into four treatment groups with three replicate pens per treatment group (12 birds each). The dietary treatments were a control diet without black cumin seeds (T1) or with 1.5% (T2), 2.5% (T3) or 3.5% (T4) of grounded black cumin seed (BCS) in the diet. The study lasted for 35 days.
