This study conducted to evaluate the effect of prebiotics (Fermacto) and isoleucine and their combination on performance and some blood parameters of broiler chickens during finisher period. At the first of experiment 300 one-day-old mixed Ross broiler chicks reared in same condition according to Ross manual guide up to 21 days old. Chicks at 21 day old were randomly allocated to 20 groups of 15 birds in a completely randomized design with 4 treatments and 5 replications. Control group were fed with the basal diet of corn-soya and wheat. In the experimental group, 0.1% of prebiotics and 0.04% isoleucine were added. Weight gain and feed intake of birds were measured and at the end of the experiment one bird from each pen were sampled and weighed and then killed. The results showed that prebiotics and isoleucine significantly (P<0.05) improved feed conversion and weight gain and serum cholesterol but it did not have any significant effect on traits such as feed, the serum amount of urea, uric acid, triglycerides, low density lipoprotein(LDL), high-density lipoprotein(HDL), very low-density lipoprotein(VLDL), LDL/HDL and serum total protein.
