Abstract: 

In this study 600 Cobb 500 broiler chickens were divided in six similar groups (A, B, C, D, E&F) with 100 chickens in each group (with four replicates of 25 chickens in each group). 100 g/ton growth promoter antibiotic in experimental group (B), 100 g/ton Prebiotic in experimental group (C), 800 g/ton Acid fires in experimental group (D), 1 kg/ton MOS in experimental group (E) and 4 kg/ton Yeast cell wall in experimental group (F) were added to the basic diets however the control group (A) chickens were fed only with the basic diet. Every week 100 chickens from each group were selected randomly and productive parameters such as weight gain, FCR, EEF, mortality, feed intake (FI) were calculated. On days 9, 17 and 25 of growth (1 day before and 7, 14 days after first Newcastle B1 vaccination), from each groups, each time 20 chickens were chosen randomly and serum antibody titres of these chickens were measured against Newcastle vaccine by HI test. The results obtained from statistical analysis indicated that using natural growth promoting substances not only increases humoral immunity but it also leads to improvement of productive parameters (p<0.05).
