BACKGROUND: Salmonella Enteritidis in poultry is one of the main causes of illness that can be controlled effectively by some plant compounds, antibiotics and probiotics. OBJECTIVES: This study compares the effect of rosemary, thyme, propolis, antibiotic and probiotic on the immune system and blood parameters of broilers challenged with Salmonella Enteritidis. Methods: Four hundred and twenty 1-day- old male broiler chicks Cobb strain were divided into seven groups: including rosemary ethanol extract, ethanol extract of propolis, ethanol extract of thyme, and probiotics, virginiamycin (10%) and positive and negative controls, and were reared for 6 weeks. At the end of experiment chickens were sampled and slaughtered. RESULTS: The results showed that plant extracts with probiotics can improve the immune system, reduce serum lipids, reduce harmful bacteria such as Salmonella and E.coli and increase the beneficial bacteria such as lactic acid bacteria. CONCLUSIONS: This study showed that the herbal extracts and probiotics can be used as an alternative to antibiotics in broiler diets.
