The present study was conducted to evaluate the adding of the commercial product (AROMAX®) (Eucalyptus oil, Mint oil, L-Menthol, Thyme oil) essential oils as a protective product against respiratory diseases and respiratory problems due to low management level in the broiler during the period from December – Novemer 2016. Also, to determine its effect on some parameters such as: local and humoral immunity, body performance and levels of liver enzymes. A total of 210 one-day- old broilers Ross 308 mixed sex were divided into seven equal groups (30 chicks each group). The results of the final body weight showed that the differences were not significant among groups. The weight gain showed that G2 (576.60 gm) was significantly higher (P<0.05) as compared with other groups. Also the results of lesion score of air sac recorded the G7 was significantly differed (P<0.05) as compared with other groups. The results of local immunity (IgA) indicated that the groups G2, G3, G4 showed significant differences at (P<0.05) compared with other groups in all periods. The result of liver enzymes (ALT and AST) showed that the means in the G3, G4 ( ALT- 4.20, 4.22) (AST- 214.4 212.6) were significantly different (P<0.05) compared with other groups. In conclusion: The AROMAX® product reduced the respiratory signs resulted from the low management, and improved the local and humoral immune response in broiler.
