Impact of dietary Anise seeds powder and oil (Pimpinella anisum) as natural additive on Immune response and some blood parameters of broilers chickens

This experiment, which was carried out in the Sako poultry project in Erbil, Iraq, from January 9 to December 10, 2021, sought to ascertain the effects of using anise seed and oils as natural additives in broiler feed on the immune feed response and several blood parameters of broilers. We randomly allocated 180 broiler chicks into four groups. T1: control; T2: a standard diet with 2 g of anise powder per kg of food; T3: a standard diet with 1 ml of anise oil per kg of diet; T4: a regular diet with 1 g of anise powder and 0.5 ml of anise oil; and Results demonstrate that adding anise seed powder and oil as a natural additive to ration boosts broiler immunity and WBC count while having no effect on broiler RBC, PCV, or Hb.
