Abstract

An experiment was conducted to assess the influences of different growth promoters on performance, carcass characteristic
and intestinal microflora of broiler. Day-old broiler chicks from Arian strain (384) were used in the completely randomized
experimental design during 7-42 days of age. Eight rations were formulated as a follow 1: control (without growth
promoters); 2-control + formic acid (0.25%); 3-control+ viginamycin (250 g/ton); 4-Contro + saccharomycis cerevisiae
(0.1%); 5-Control+ viginamycin (250 g/ton)+ formic acid (0.25%); 6- Control+ viginamycin (250g/ton)+ formic acid
(0.25%); 7- Control+ viginamycin (250 g/ton)+ saccharomycis cerevisiae ( 0.1%); 8- Control+ viginamycin (250 g/ton)+
saccharomycis cerevisiae ( 0.1%).. The treatments with 3 repetition and 16 birds per parcel were used. The formulated rations
were fed to 384 day-old Arian. Each treatments consisted 3 replicate with 16 birds per parcel. Obtained results indicated that
formic acid had no significant effects on all measured parameters, nevertheless supplementation of diet with antibiotic
