The aim of this research is to Study the effect of adding 1 gm, 3 gm and 5 gm of plantagolanceolata powder per kg of basic diet food on bodyweight, Feed intake, Blood urea, Creatinine and Antibody titer against Newcastle disease of broilers. Two hundred (200) unsexed broilers of Rose (308) strain were used in this experiment and the experiment was performed for the day 1 of chicken life until five weeks (35 day). The broilers were divided in to four group and each group contain 50 broilers, the first group (T1) were fed on a basic diet, the second group (T2) they were fed on basic diet plus 1 gm from plantagolanceolata powder per kg of feed, the third group (T3) they were fed on basic diet plus 3 gm from plantagolanceolata powder per kg of feed and the fourth group (T4) they were fed on basic diet plus 5 gm from plantagolanceolata powder per kg of feed. Environmental temperature in the first week of life was 32ºC and decreased 2ºC a week till to 25ºC till the end of the experiment. As for the light. It was provided one hour darkness and 23 hour light .At day 35th of age the blood sample from wing vein were collected in a test tube without anticoagulant. The serum was separated by centrifugation for 5 minutes at 3000 rpm and stored in a deep freeze (-20) until analysis. Through the current study and after the end of the experiment there is a significant (P<0.05) increase in weight gain in T3 group that received 3 gm of plantagolanceolata which also showed a significant (P<0.05) decrease in feed intake when compared to the other groups. While blood urea show a significant (P<0.05) increase in T3 when compared to the other group. On the other hand Creatinine level show no significant deference between groups, while T4 show a significant (P<0.05) decrease in the Antibody titer against Newcastle disease
