The experiment included 300 one day-old chickens, which were divided into 5 groups: control (1C), experimental with pollen supplement in amount of 15 g. kg-1 (2nd group) and 45 g. kg-1 (3rd group). Broiler chickens of 4th and 5th groups were fed with propolis ethanol extract supplement in amount of 400 mg.kg-1, 800 mg.kg-1, respectively. After fattening, broilers were processed by stunning, bleeding, scalding, and picking. Susceptibilities to antimicrobial agents were tested using the disk diffusion method with according to the CLSI requirements, using the following antimicrobial disks: vancomycin (VAN) 30 μg/disk, gentamicin (GEN) 120 μg/disk, erythromycin (ERY) 15 μg/disk, teicoplanine (TEI) 30 μg/disk, ampicillin (AMP) 10 μg/disk (Oxoid). The isolates were classified as susceptible, intermediate resistant or resistant.

For microbial examination (30 samples) were whole crops, ileum and caecum aseptically removed from five carcasses per group (10 from control group).
