  This experiment was conducted in order to investigate the effect of black pepper, garlic and turmeric powders on performance and antibody titer against Newcastle virus of broiler chickens using 448 Cobb 500 one day broiler chickens including male and female with 8 treatments in a factorial arrangement (2×2×2). Experimental treatments consisted of T1 (as control), T2 (black pepper powder), T3 (turmeric powder), T4 (garlic powder), T5 (black pepper and turmeric powders), T6 (black pepper and garlic powders), T7 (turmeric and garlic powders), T8 (black pepper, garlic and turmeric powders). Each treatment had 4 replicates and 14 chickens per replicat. In this experiment, two blood samples were collected from each replicate at 28 day-old birds. One week later the same pieces of chickens were bled when they were 35 days old and the sample was sent to the laboratory in order to measure antibody titer against Newcastle virus. As the mean of Newcastle antibody titer before and after vaccination was compared, a significant difference between treatments was appeared when they feed additives separately . However no significant difference was revealed between treatments when the additives were added simultaneously . At the end of trial, two broiler̛s were slaughtered and spleen of chickens from each treatment were weighed. So, the results showed that there was a meaningful difference among treatments in spleen's relative weight when feeding additives individually. But in the case of feeding with all three additives simultaneously , there was a significant difference between treatment 8 and control group . Evaluation of the results for feeding intake during whole period indicated a meaningful difference between treatment 5 and treatment 7. No significant difference was observed between treatments for weight gain and conversion ratio during whole period of the experiment. So, the use of additives simultaneously can positively affect on both the relative weight of spleen and feed intake, but for Newcastle titer, the additives can improve Newcastle titer only before vaccination. Also consuming black pepper powder and turmeric powder separately after and before vaccination, influenced positively on Newcastle titer, but garlic powder had no effect in this case.
