Th e aim of this study was to evaluate the eff ect of adding diff erent dosages of live yeast (Saccharomyces cerevisiae) in diet on
growth performance, carcass characteristics, intestinal morphology, and gut microfl ora of broilers. Th e study was conducted on 270 oneday old chickens (Ross 308) during a 42-day period. Broilers were randomly allocated to one of three dietary treatments that diff ered in
the content of added yeast: no additional yeast; with 0.25 g/kg; and with 0.65 g/kg of added yeast. Each experimental group contained 90
animals. Th e results from our study showed that diet supplemented with 0.25 g/kg of yeast resulted in better growth performance and
carcass quality (P<0.05), improved intestinal morphology (P<0.001), higher development of beneficial microfl ora (Lactobacillus spp.)
(P<0.01), and reduction of pathogenic bacteria (Escherichia coli) in guts of broilers than in the group fed only with the basic diet (P<0.05).
On the other hand, the group with the hig...hest inclusion of yeast in diet (0.65 g/kg) achieved similar results for the examined parameters
as did the group with no added yeast. Th erefore, the adequate dose of S. cerevisiae in diet was 0.25 g/kg of yeast, while higher dose of live
yeast in broiler diet (0.65 g/kg) did not achieve better results.
