An experiment was conducted to evaluate the effect of different levels of threonine on microbial carcass with use of 450 numbers of broiler chicks of the Ross 308.The chicks randomly are allocated to five experimental treatments and six replications (15 chicks in each replicates) in a completely randomized design. The experimental diets are including different levels of threonine with five levels of 90, 100, 110, 120 and 130 percent of the recommended Ross 308. The findings of the study shows the effect of experimental diets on microbial carcass in female and male broiler are (p< 0.05) significant. In carcass broiler chicks (different treatment) salmonella are not observed (P> 0/05). In dilution (-1) most level microbial carcass in treatment 90 ٪Threonine became observation, where with treatment 110 ٪threonine are significant (p< 0.05). Dilution (-2) least level microbial carcass in treatment 110 ٪became observation than another treatments are significant (p< 0.05).Too in total content microbial carcass least level relevant on treatment 110 ٪threonine was than another treatments are significant (p< 0.05). Results showed that the increase of threonine up to %10 leads to improvement of broiler chicks.
