Evaluating the Competitiveness of Medicinal Plants With Antibiotics to Control Salmonella Enterica Serovar Typhimurium in Broiler Chickens

Background: Salmonellosis is one of the important diseases in poultry industry, which also causes public health concerns. Objectives: We studied effects enrofloxacin and herbal medicines on growth performance, blood parameters, meat oxidation, cecal microbial population broilers challenged with Salmonella enterica serovar Typhimurium (ST). Methods: A total 240 one-day-old (male) Ross 308 broiler chicks were randomly divided into 6 groups: negative positive control, enrofloxacin, three (A, B, C) containing different proportions cinnamon, thyme, licorice, marjoram extracts compounds organic acids. The dosage A, C 1, 2 mL/L drinking water, respectively, prescribed from days 16 to 21. On day 10, all groups except control 1 mL suspension 1×107 CFU/mL ST. Performance traits measured intervals 1-10, 11-24, 25-42, 1-42 days. Blood Results: Among groups, medicine showed lowest levels infection (P<0.05). Medicine B had a better effect performance amount malondialdehyde meat. Medicines caused cholesterol triglyceride concentration serum Conclusion: above-mentioned can be used as beneficial additives nutrition improve reduce gastrointestinal tract, cholesterol, triglycerides, oxidation.
