| Abstract | ||
| This study was conducted at the Poultry Farm of the Faculty of Agriculture, University of Kufa, during the period from 16 March to 19 April-2015, for 5 weeks. A total of 240 chicks of Ross308 hybrid broiler were used and, distributed randomly to four treatments (60 chicks.treatment-1) 3 replicate each treatment with 20 chicks.rep-1. The chicks were fed on two diets, starter diet for the first 21 days of age and finisher diet for the rest 22-35 days of age. The treatments were as follows: (T0) control: without any addition, (T1): Addition of 250 mg Marjoram oil.kg-1feed diet, (T2): Addition of 500 mg Marjoram oil.kg-1 feed diet, (T3) Addition of 750 mg Marjoram oil.kg-1 feed diet, to investigate the effect of addition of different levels of Marjoram oil on productive and immunity responses of broiler. The results revealed that no significant differences between control and experimental treatments (with addition of Marjoram oil) on live body weight, body weight gain and feed conversion ratio, while T3 showed superiority significant effect in feed consumption, Red blood cells, white blood cells, PCV and height level of antibodies against Newcastle disease as compared with control. It can be concluded that the addition of marjoram oil to the broiler diet showed a positive effect in blood characteristics, levels of antibodies against Newcastle disease and feed consumption. | ||
