Effects On Production Performance and Ileal Microflora of Broiler Chicks by Adding Various Levels of Coriander Seed (Coriandrum sativum L.) Powder to Ration

  The aim of the current study was to assess the impacts of adding various levels of coriander (Coriandrum sativum L.) on broiler production efficiency and ileal microflora. Five treatments, consisting of 90 ROSS (308) broiler chicks each, were created from a total of 450 broiler chicks that were one day old. Each therapy was applied three times (30 chicks per replicate).The experiment included five treatments: a control diet without coriander, a control diet supplemented with four levels of coriander powder (0.2%, 0.4%, 0.6%, and 0.8%). After 21 days, the value of final weight, weight gain, feed intake, and feed conversion ratio were increased significantly in the birds received diet that contained coriander compared with control. However, this trend was not significant in the day 35 and day 42 of experiment. These findings suggested that synthetic antibiotics might be replaced in poultry diets by natural feed additives and growth enhancers like coriander powder.
