Liquid smoke has not been used as antimicrobial agents in poultry feed. Therefore, the purpose of this research was to evaluate the effect of liquid smoke from coconut shell on the ileal characteristics and microflora population in broiler chicken. The method was in vivo experiment by using Completely Randomized Design. One-hundred-and-forty-day old chicken of strain Cobb allocated into 4 treatments and 5 replications. The treatments consisted of T0= basal feed added with antibiotic. T1=basal feed + 0.5% liquid smoke, T2=basal feed + 1% liquid smoke, and T3=basal feed + 1.5% liquid smoke. The measured variable was: ileal length and weight, pH and viscosity of ileal content, population of microflora consisted of Lactobacillus, Escherichia coli, dan Salmonella sp. Data were analyzed with ANOVA and if significant result was obtained then continued with Duncan’s multiple range test. The results showed that there were no significant different (P>0.05) effect of treatment on intestinal characteristic values, but it significantly affected (P<0.01) all microflora population. Conclusion of this research was addition of smoke liquid up to 1.5% does not cause a negative effect on intestinal characteristics, but improve non-pathogenic microflora population in broiler chicken. It might suggest that liquid smoke could be consider to replace the use of antibiotic in broiler feed.
