The objective of this study to investigate the clinical signs of Newcastle Disease (ND) in infected broiler farms of Iran Northwest and to determine serological status of this flocks and healthy flocks. Also the mortality was compared in healthy and infected flocks. From 22 broiler flocks blood samples were collected and examined with HI test. Mortality rate was documented in each flock. For Data analyzing Independent samples T test statistical method was used for compare infected and healthy flocks and statistical software was PASW SPSS 18th edition. Results of HI test showed that mean of antibody titers in healthy flocks was 5.36±0.20 and in infected flocks was 8.63±0.28. The data was demonstrated that there were significant differences between groups. The mortality rate in infected flocks was 33.20±4.11 and in healthy flocks was 12.99±1.12 percent (p<0.05). Because of economical losses causes by growth decrease, increase of feed consumption due to ND disease, it is necessary to applying exact vaccination programs in broiler flocks and observe of biosecurity to decrease mortality rate and losses due to decrease of growth.
