  Abstract: This research aimed to investigate the attitude of broiler breeders toward the production of antibiotics-free chickens in Tehran province. The statistical population in this study included all broiler breeders (N=450) in Tehran province. Using stratified-random-sampling method 136 breeders were selected. The main tool for data gathering was a questionnaire contained 44 questions and items. Results showed that 52.9% of the respondents had “positive” or “relatively positive” viewpoints about the production of antibiotic-free chicken. The results also indicated that there were a significant (p < 0.05) positive relationship between the attitude of  production of antibiotic-free chicken with the education level, job satisfaction, second job as well as having technical supervisor. Moreover, a significant (p < 0.01) positive relationship was observed between the participation in training courses related to the production of antibiotic-free chicken and the viewpoint of studied broiler producers. On the other hand, no significant correlation was observed between the “viewpoint of chicken producers” and the variables such as: “age”, “job background”, “frequency of progeny”, “production/non-production of antibiotic-free chicken”, “consumption/non-consumption of antibiotic-free chicken” and “knowledge on breeding the antibiotic-free chicken”.    Manuscript profile
