controlled coccidiosis by providing anticoccidial drugs in poultry feed, this approach
is becoming less desirable in light of growing public concern about food safety.
Presently, vaccination consist of infecting young poultry with a known dose of live
coccidian parasites. This vaccination will immunize poultry against the disease, The probiotic

The objectives of this study are: to compare the effect of additive and nonadditive of probiotic feed
supplement (Enteroccus faecium) in the: diet contains anticoccidia on performance of broiler, diet without
anticoccidia or vaccine (control) on performance of broiler, diet contains coccidia vaccine on performance
of broiler.
Key words:
